Now that Florida is facing its annual cold season, it’s time to think about frost protection. Even here in Zone 10a, the temperatures can drop overnight, even to freezing and below. For Southern gardeners whose passion is tropical gardening, temperatures below just 50°F can be devasting. So, what ARE the best greenhouse kits for Southern gardens and our unique needs?
Between blistering sunlight in summer, torrential downpours, and sudden sharp frosty nights, gardening in Florida — or anywhere along the Gulf Coast — can be quite a challenge. The best greenhouse kits for Southern gardens will provide protection from frosts, hot sun, and torrential downpours.
Currently, we’re enjoying a freak winter downpour. Since it’s following a long drought, I’m not going to complain. But so far, my fall tomato plants have already been fried, drowned, and tipped with cold damage. Granted, I have a love-hate relationship with tomatoes.
A few years ago, my husband promised to build me a greenhouse. He even described his elaborate plans to reuse some PVC pipe. That was in 2020, after we had already spent four months rushing outside during the rare bitter cold snap, teeth chattering, covering tomato plants with every spare sheet or blanket we could find.
Then, we “enjoyed” the freak three-night freeze of 2022, and I knew it was time to invest in a real greenhouse, even if I didn’t have much of a budget.
What was the best greenhouse I could find without breaking the bank?
While I have three growing seasons here, it seems that my fall garden plants just get started producing in the winter when we suddenly get a cold snap.
It’s the same with the spring — they just get established and start to bloom when a blistering hot day puts an end to progress.
I knew that I really COULD grow fool all year round if I had the right infrastructure. It’s entirely possible to grow all year long, if you have one of the best greenhouse kits for extending the season.
For example, it’s still too hot and humid in September to grow large tomato varieties, and they don’t really get going until October. That leaves them vulnerable in late December and January.
And while most people use their greenhouse in the winter, I decided that I could also use a greenhouse kit in the summer by adding a shade cloth to keep out the worst of the afternoon sun.
I lucked into the best buy I could make when I discovered the King Bird greenhouse that included a sprinkler kit for cooling off during the hot summer.
Wouldn’t it be great to have a shade house in place to save time (and sunburn)?
Most
gardeners in the South just take the summer off. But the best greenhouse kit
could be quickly modified with some shade cloth.

When I purchased my King Bird, I also purchased two of these pop-up greenhouses for emergency use. They were on sale at the time, and I couldn’t resist the price.
These are especially useful for covering in-ground climbing plants like cordoned tomatoes or cucumbers. I purchased them for hanging houseplants and in the hope that they would be easy to put up by myself when I sold plants at local farmer’s markets.
It turned out they were a bit too heavy for the purpose, but one has made a most excellent shade house. The structure is easily sturdy enough to hold many hanging plants for display. And it’s shady enough for Monstera and pothos on poles, too.

Using a Greenhouse in Florida and Other Hot Climate Zones
A Jump on Spring
I normally start my spring seeds in December. But quite frankly, I don’t have enough room for everything if we get a cold night. Last year, I moved dozens of seedlings inside when the temperatures plummeted. I lost a few trays because I foolishly stacked them and they crushed each other.
But a
greenhouse means I’ll have plenty of room to keep my starts toasty and safe all
winter long. I may even get some spring tomatoes this year.
Variety
is the Spice of Life
Speaking of tomatoes, because I live in an area of the country that suffers from terrible heat and humidity, I have trouble growing big tomato varieties. They just suffer under the sun long before they produce.
So, I’ve
been focusing on early maturing varieties and cherry tomatoes – which means I
don’t get to enjoy the wide variety of heirloom vegetables I want to grow.
Choosing the Best Greenhouse for Winter
Too often, I’ll jump into buying something for my garden on a whim. Just ask me about all those soaker hoses I bought last month.
But in this case, I’m doing my research and due diligence before making a big purchase that will take up a lot of yard space.
Here are some things to think about before choosing a greenhouse.
Code Violations
In some neighborhoods or towns, you may need to get a permit. Usually, this will be for a permanent structure, perhaps with an electrical line or water access. You probably won’t need one for a small portable greenhouse or hoop house.
But do check with your local planning commission about what type of structures require a permit.
And don’t forget to check with your HOA or neighborhood association to make sure it doesn’t violate their requirements.
Allocating
Space
Do
you have enough room on your property for a greenhouse? Sometimes, you’ll find
that the best place to put it for maximum efficiency is smack-dab in the middle
of your back yard.
You’ll want it in the sunshine for the winter, but remember that placement under a tree canopy can help protect plants from a hard freeze, too.
Make
the most of any southern exposure available to help keep your greenhouse warm. Also,
placing your greenhouse near a light-painted wall with southern exposure can be
the warmest spot in the yard. Buildings can reflect sunlight onto nearby plants
as well as absorb heat during the day and release it over the night.
Place your greenhouse so it gets at least six hours of sunshine during the day. And remember, it’s also a good time to trim trees and bushes during their dormant periods.
Accessibility
You’ll also want to place your greenhouse where it’s easy to access from your home. Especially if it gets cold, you’re more likely to keep an eye on things if you don’t have to freeze to do so.
You may also want access to the outdoor hose bibb or GFCI outlet. Adding a portable electric heater turns even a cheap model into one of the best greenhouse kits for growing vegetables in the winter.
Knowing
where you’re going to place it will help you narrow down all the possible
choices to one that will work best in your garden.
Features
to Look for in the Best Greenhouse Kit
Greenhouse kits come in a wide range of price points and durability options. You can find inexpensive models that hold a few shelves of seedlings for very little money. You can also find models the size of a small family bungalow, with sturdy metal frames.
So,
think of what features you might need to get started.
How
Big?
Last
year, I only set up a few seed trays to get my spring garden started. So, I
really only needed an economy model.
If you’re just getting a jump on spring starters for early vegetables, a smaller indoor/outdoor model will probably be one of the best greenhouse kits for you.
However, if you’re growing a significant number of plants and rely on them to feed your family, you may want to look at a more sizeable model. You’ll find hoop houses provide plenty of room for low cost.
If you need to overwinter delicate full-grown plants, you may want to look for height in a greenhouse as well as square footage. Check out models that offer shelving systems and hanging hooks.
And if you want to make a statement in your landscape design, take a look at some of the best greenhouse kits from makers like Grandio and Palram. While they do require some DIY skills to assemble, they’re much less expensive than hiring a contractor to build one.
Construction
Materials
Portable greenhouses use plastic sheeting to protect your plants from the elements. The thickness can vary, but most provide adequate protection from winter chills in Zones 8 to 11.
More durable greenhouse kits use polycarbonate sheets, which are clear plastic, but sturdy like acrylic sheeting.
Poly-Sheeting
Greenhouses
Most portable and economy greenhouse kits include polyethylene plastic sheeting and a frame made of aluminum, steel, or PVC piping.
The polyethylene
plastic sheeting in kits usually runs between 2 to 6 mils thick. Although it
may not last more than two or three years, you can also patch or even replace it
should it be required.
Polycarbonate Greenhouses
The
best greenhouse kits feature polycarbonate plastic panels in an aluminum frame.
While they’re more expensive, they’re suitable for permanent installation.
However, they’re also harder to assemble. Especially if you’re planning on adding electricity and water to your greenhouse.
But
if you have the DIY skills, they can really make a statement in your
landscaping. Many are quite charming and attractive.
Commercial
Greenhouse Kits
At one point in my budding horticultural career, I considered starting a hobbyist nursery. Then I discovered that you needed an inspection to sell plants to other gardeners. The good news was that I didn’t need one to sell produce.
A commercial size hoop house is just the thing if you have the room or are thinking of expanding into an urban farm.
Remember to check with your local extension office about any laws or regulations in place for your state. But who knows, you may have discovered the side gig that opens up a whole new career.
Greenhouse DIY
If you’re looking for a build your own greenhouse kit, you’ll find plenty of plans available online. All it takes is a few DIY skills and access to your local home improvement center.
And depending on your needs and ambition, you can build something as simple a hoop house or something as intricate and challenging as a solar-heated grow hut.
Walden Labs offers free plans online. I’ve been saving soda bottles for their Recycled Model for about a year now.
And if you’re looking for a fun craft, this small greenhouse DIY uses CD cases to create a cloche for a treasured favorite.
Gimme
Shelter
I’m still not sure which one I’m going to opt for, but something tells me that I’m picking out my own Christmas present this year.
Either
way, the best greenhouse kits are the ones you can afford and the ones you can
use.
It may seem odd to get a greenhouse when you live in Florida and only get a few cold nights a year. But it will be nice knowing that I won’t have to stumble around in the dark, covering up whatever I can manage to see with whatever I can manage to find.

Whether you’re a novice or an experienced gardener, mastering the skill of seed germination is a fundamental skill. It’s the first step to a bountiful and abundant harvest. So, let’s dive into the seed starting basics of germination and provide you with valuable insights on how to successfully kickstart your garden from the very beginning.
How Seeds Germinate
Seed germination is a remarkable process by which a dormant seed transforms into a tiny, delicate seedling. Understanding the science behind this empowers you to become a more proficient seed starter. You’ll be able to give your plants the best possible start. Let’s take a look at nature at work.
The Anatomy of a Seed
Seeds are remarkable storehouses of life. They consist of three key parts:
embryo
endosperm
seed coat
The embryo is the embryonic plant inside the seed, containing the first leaves (cotyledons), the stem (hypocotyl), and the root (radicle).
The endosperm, a nutrient-rich tissue, provides nourishment to the developing embryo.
Finally, the seed coat acts as a protective shell, shielding the delicate contents from external threats.
Image from page 372 of “Plant life and plant uses; an elementary textbook, a foundation for the study of agriculture, domestic science or college botany” (1913)
The Trigger: Absorption of Water
The germination process begins with the absorption of water through the seed coat. As the seed absorbs water, it rehydrates. The dormant embryo awakens from its slumber.
This rehydration process also activates enzymes that break down stored nutrients within the endosperm, transforming them into simple sugars and other essential substances for the seedling’s early growth.
Activation of Growth Hormones
Water absorption triggers the production of growth hormones called gibberellins, which play a pivotal role in stimulating the embryo to initiate growth.
Gibberellins activate enzymes responsible for cell division and elongation, propelling the embryo’s root (radicle) to emerge from the seed coat in search of moisture and nutrients.
Emergence of the Root
As the root (radicle) elongates, it breaks through the seed coat and emerges into the surrounding soil.
The radicle becomes the primary root of the seedling, anchoring it in the growing medium and absorbing water and essential nutrients.
Unfurling the Cotyledons
Simultaneously, the stem (hypocotyl) elongates, pushing the cotyledons (seed leaves) above the soil surface.
Cotyledons vary in number and shape depending on the plant species and can be either one or two. These early leaves are instrumental in photosynthesis and provide the young seedling with initial sustenance until true leaves develop.
Photosynthesis Commences
With the cotyledons exposed to light, the process of photosynthesis begins.
Through photosynthesis, the seedling synthesizes glucose, a vital energy source, from carbon dioxide and water using sunlight.
This metabolic activity fuels the seedling’s growth, allowing it to develop into a robust and self-sustaining plant.
The intricate processes of water absorption, hormone activation, and the emergence of roots and cotyledons collectively orchestrate a marvelous transformation.
What Seeds Need to Germinate
Seed germination is a critical stage in a plant’s life cycle, and providing the right conditions is essential for successful germination.
While individual plant species have specific germination requirements, some general factors influence seed germination across most plants.
Understanding these factors will help you create an optimal environment for seedlings to emerge and thrive.
Moisture
Water is a primary trigger for seed germination. During imbibition, the seed absorbs water, leading to the activation of enzymes that initiate metabolic processes and growth.
Sufficient moisture is vital during germination to ensure the seed swells, softens the seed coat, and facilitates the emergence of the radicle.
Warmth
Temperature plays a crucial role in germination. Each plant species has an optimal temperature range for germination.
Seeds typically require warmth to activate enzymes and metabolism. Low temperatures can slow or inhibit germination, while high temperatures can cause damage or desiccation.
Seeds respire during germination, converting stored energy into usable forms. Adequate oxygen supply is essential for these metabolic processes.
Soil structure and porosity influence the availability of oxygen to seeds in the growing medium.
Light
Light requirements for germination vary among plant species. Some seeds require light to trigger germination, while others germinate best in darkness.
Photoreceptor proteins in seeds sense light levels and influence germination responses.
Factors that Affect Seed Starting and Germination
Seed Coat Permeability
The seed coat serves as a protective layer, and its permeability affects germination.
Some seeds have hard or impermeable seed coats, requiring scarification (mechanical or chemical abrasion) to enhance water absorption and germination.
Seed Dormancy
Scarification involves breaking or weakening the seed coat, promoting germination. Stratification refers to subjecting seeds to cold treatment, mimicking winter conditions.
Both techniques are used to overcome seed dormancy and synchronize germination with favorable conditions.
Germination Inhibitors and Hormones
Some seeds contain chemicals that inhibit germination until specific conditions are met.
Others require exposure to hormones like gibberellins or cytokinins to initiate germination.
Germination Time
Different seeds have varied germination periods. Some seeds germinate quickly, while others may require several weeks or even months.
Understanding the expected germination time helps manage expectations and avoid premature intervention.
Seeds that Need Light to Germinate
Some seeds need sunlight exposure to germination. Sunlight acts as a signal to the seed that it is close to the surface of the soil and has good conditions to begin growing.
Light-sensitive seeds won’t germinate if planted too deep in the soil.

Seeds that Need Cold Stratification to Germinate
Many seeds from temperate climates have built-in dormancy mechanisms that prevent immediate germination.
This can be a problem when gardening in warmer climates in Zones 8-12. We rarely get enough cold or long enough during the winter to stimulate these kinds of plant seeds.
In this case, cold stratification, a process of subjecting seeds to cold and moist conditions before seed starting, mimics winter conditions. This breaks seed dormancy, allowing them to germinate.
This treatment triggers biochemical changes within the seeds, preparing them for germination once conditions become favorable.

How to Nick and Soak Seeds to Improve Germination
Seeds with tough outer coverings often require some help stepping out of their shells. You can nick the casing and soak them to speed up germination when seed starting these types.
Step 1: Gather Materials
Gather the seeds you wish to nick and soak. Ensure they are seeds that require scarification (nicking) or soaking for enhanced germination.
Step 2: Prepare the Nicking Tools
Use a pair of sharp scissors, a nail file, or sandpaper to nick the seed coat. Sterilize the tools with rubbing alcohol before use to prevent the spread of pathogens.
Step 3: Nicking the Seeds
Hold the seed firmly but gently with your fingers or tweezers to avoid damaging the embryo.
Locate the seed’s opposite end from the hilum (scar) where it was attached to the parent plant.
Make a small, shallow cut or nick on the opposite end of the seed coat using the prepared tools.
The goal is to break through the hard outer layer without damaging the delicate inner part of the seed.
Step 4: Soaking the Seeds
After nicking the seeds, place them in a container suitable for soaking. Glass or plastic containers work well.
Fill the container with warm water, about 100 degrees F or so. It should feel slightly warmer than your skin temperature. Cover the seeds completely. Don’t use water that’s too cold or too hot, as extreme temperatures may harm the seeds.
Let the seeds soak for the specified duration, which varies depending on the type of seeds. Some seeds may require only a few hours, while others may need overnight soaking.
Step 5: Monitor the Soaking Process
Keep a close eye on the seeds while soaking to prevent over-soaking. Different seeds have different soaking times, and excessive soaking can lead to seed damage or rot.
Step 6: Drain and Plant
Once the soaking time is up, remove any seeds that are floating in the water. They will likely not germinate
Drain the water from the container. Place the nicked and soaked seeds on a damp paper towel to remove excess moisture.
Plant the seeds immediately after nicking and soaking, following the recommended planting depth and spacing for each seed type.
Remember that not all seeds require nicking and soaking for successful germination. Generally, those with hard shells can be soaked prior to planting
However, make sure you research the specific germination requirements of each seed type before proceeding.
How to Cold Stratify Seeds
Seeds from plants native to cold climates or those with natural dormancy mechanisms may require cold stratification before planting.
Find a sealable plastic bag or airtight container. To this, add a small amount of moistened coconut coir, perlite, or vermiculite to the container.
Then, place the seeds on top of the damp medium.
Seal the container and label it with the seed type and the date of stratification.
Place the sealed container in the refrigerator, where it should remain at a consistent temperature between 32 to 45 degrees Fahrenheit.
The duration of cold treatment varies depending on the seed type, so you’ll need to do some research on your specific seeds. Some require a few weeks while others require several months.
Check the container periodically to ensure the medium remains consistently moist. Add a few drops of filtered water if the medium seems too dry.
After the required cold stratification period, remove the seeds from the refrigerator and allow them to warm up gradually at room temperature for a few days.
You can then sow your cold-stratified seeds following the recommended planting depth and spacing for each seed type.
Cold stratification is a valuable technique for enhancing the germination of certain seeds. It mimics natural winter conditions and prepares seeds to sprout when the warmer temperatures of spring arrive.
Planting Depth and Its Impact on Successful Growing
Planting depth is a critical factor in seed germination and seedling establishment, as it directly influences various physiological processes in plants.
Understanding the scientific aspects of why planting depth matters can help gardeners make informed decisions to achieve optimal growth in their gardens.
Here’s a scientific perspective on the importance of planting depth and its impact on successful growing:
1. Soil Temperature and Moisture
Planting depth affects the soil temperature experienced by the seed. Seeds planted closer to the surface experience higher soil temperatures, promoting faster germination.
Deeper planting can result in cooler soil conditions, which may delay germination.
Additionally, proper planting depth allows seeds to access adequate soil moisture levels, which are essential for initiating metabolic activities and cellular processes during germination.
2. Seed Respiration and Oxygen Availability
During germination, seeds undergo respiration, a process that provides energy for growth.
Adequate oxygen availability is crucial for efficient respiration.
Shallow planting ensures better oxygen diffusion to the embryo, promoting healthier seedling development.
Deeper planting may reduce oxygen diffusion, leading to suboptimal respiration and potentially weak seedlings.
3. Photomorphogenesis and Light Perception
Photomorphogenesis is the process by which light influences plant growth and development. Some seeds exhibit photoblastic behavior, responding to light for germination.
Seeds that require light for germination (positive photoblastic) should be surface-sown to ensure they receive sufficient light.
On the other hand, seeds with negative photoblastic behavior, which require darkness for germination, should be planted at the appropriate depth to shield them from light.
4. Hypogeal and Epigeal Seedlings
Hypogeal and epigeal seedlings are terms used to describe two distinct types of seed germination and the initial stages of seedling development.
These terms highlight the differences in how seeds sprout and the subsequent growth patterns of emerging seedlings.
Understanding these concepts is crucial for successful gardening and plant propagation.
Hypogeal Seedlings
Hypogeal germination is characterized by the emergence of seedlings where the cotyledons, or embryonic seed leaves, remain below the soil surface.
In this type of germination, the cotyledons do not emerge above the ground but stay within the protective shell of the seed coat.
Instead, the epicotyl (the embryonic shoot) elongates and pushes the cotyledons and growing point above the soil.
Key Features of Hypogeal Germination
Cotyledons remain below ground.
Epicotyl elongates and emerges above the soil.
Cotyledons remain enclosed in the seed coat.
Typically observed in plants like beans, peas, and sunflowers.
Examples of Hypogeal Seedlings
Beans (Phaseolus vulgaris): Beans are a classic example of hypogeal germination. When a bean seed germinates, the cotyledons remain underground while the shoot (epicotyl) elongates and emerges above the soil. The cotyledons stay enclosed within the seed coat until the shoot reaches the surface.
Peas (Pisum sativum): Peas also exhibit hypogeal germination. As the pea seed germinates, the shoot pushes upward, bringing the growing point and cotyledons above the soil. However, the cotyledons themselves remain below ground, protected by the seed coat until the shoot emerges.
Sunflowers (Helianthus annuus): Sunflowers demonstrate hypogeal germination. The shoot of the germinating sunflower seed elongates and emerges above the soil, while the cotyledons remain within the seed coat below ground.
Epigeal Seedlings
Epigeal germination, on the other hand, involves the emergence of seedlings where the cotyledons are lifted above the soil surface.
As the embryonic shoot elongates, it pushes the cotyledons and growing point upward, breaking through the soil.
Once exposed to light, the cotyledons expand and begin to perform photosynthesis.
Key Features of Epigeal Germination
Cotyledons emerge above ground.
Cotyledons expand and perform photosynthesis.
Hypocotyl (stem below cotyledons) remains short.
Common in plants like lettuce, cucumber, and sunflower.
Examples of Epigeal Seedlings
Lettuce (Lactuca sativa): Lettuce is an example of epigeal germination. In lettuce seeds, the cotyledons emerge above the soil surface as the shoot elongates. Once exposed to light, the cotyledons expand and start performing photosynthesis.
Cucumber (Cucumis sativus): Cucumber seeds undergo epigeal germination. The cotyledons of cucumber seedlings emerge above ground, and as they unfurl, they begin capturing light energy for photosynthesis.
Melons (Cucumis melo): Melons, such as watermelon and cantaloupe, also exhibit epigeal germination. The cotyledons break through the soil surface and become exposed to light, where they start their photosynthetic activity.
For hypogeal seedlings, it’s crucial to plant seeds at the right depth to ensure that the epicotyl can push through the soil.
For epigeal seedlings, proper exposure to light is essential for the development of healthy cotyledons.
Understanding these examples of hypogeal and epigeal germination provides insight into how different plants handle the initial stages of growth. This knowledge can guide gardeners in providing the appropriate care and conditions for various types of seedlings.
5. Root Elongation and Establishment
The depth at which seeds are planted affects root growth and establishment.
Shallow planting encourages early root elongation near the soil surface, allowing seedlings to access surface nutrients effectively.
Deeper planting promotes downward root growth and establishment in search of deeper water and nutrient resources.
6. Seed Coat Integrity and Imbibition
Planting depth can impact seed coat integrity and imbibition (absorption of water by seeds).
Shallow planting minimizes the risk of seed coat damage during germination, enabling optimal water uptake by the seed.
7. Seedling Competition and Spacing
Proper planting depth helps maintain adequate spacing between seedlings. Appropriate spacing reduces competition for resources such as light, water, and nutrients, ensuring healthier individual plant growth.
8. How to Determine How Deep to Plant Seeds
Planting seeds at the appropriate depth is crucial for successful germination and seedling establishment.
The ideal planting depth varies depending on the size of the seed and its germination requirements.
Here are a few ways to determine the proper planting depth for different seeds:
Research the Seed: It often helps to read the seed packet, but additional research is a good idea.
Consider Seed Size: As a general rule, smaller seeds are typically planted at shallower depths, while larger seeds can be sown deeper.
Small seeds, like lettuce or petunias, may require only a light covering of soil or none at all.
Larger seeds, such as beans or squash, may need to be planted at a deeper depth.
Observe the Seed Shape: Some seeds have distinct shapes that influence planting depth. For example, flat seeds, like sunflower seeds, should be sown horizontally at a depth equal to their width.
Rounded seeds, like peas, are often sown at a depth two to three times their diameter.
Follow Recommendations: Pay attention to any specific recommendations provided for the seed variety you’re planting.
Some seeds, particularly those that require light for germination, should not be buried and should be surface-sown instead.
Soil Type Considerations: In heavy or clayey soils, it’s essential not to plant seeds too deep, as this can hinder seedling emergence.
In loose or sandy soils, consider planting slightly deeper to ensure adequate moisture retention.
Watering Considerations: Keep in mind that seeds planted too deep may struggle to reach the surface, and their access to moisture may be limited.
Planting at the correct depth ensures that seedlings can emerge and access essential water and nutrients after germination.
When to Start Seeds
Understanding the ideal timing for seed starting is crucial for successful gardening. Properly aligning seed sowing with the distinct growth preferences of warm-season and cool-season crops is essential to achieve robust and thriving plants.
What Are Warm Season Crops?
Warm-season crops flourish in the warmth of the spring through fall growing season. These crops, including tomatoes, peppers, cucumbers, and squash, exhibit specific characteristics that make them well-suited for the elevated temperatures of these seasons.
Characteristics of Warm Season Crops
Warm season crops require temperatures between 70-85°F (21-29°C) for optimal germination and growth. They thrive when exposed to abundant sunlight and have a longer growing cycle.
Requirements of Warm Season Crops
These crops need well-draining soil, ample sunlight (8-10 hours daily), and regular moisture. They are sensitive to frost, requiring careful timing for both indoor and direct sowing.
Seed Starting Times for Warm Season Crops
Indoors: Around 6-8 weeks before the anticipated planting months, aligning with the end of winter or early spring.
In Zones 9-12, we frequently start warm-season crops indoors in late December through January for planting out after the last frost date in February or March.
We also start seeds indoors or undercover in the late summer for planting out during the milder months of September and October after the heat of summer has worn down.
Outdoors: When the danger of frost has passed and temperatures consistently stay within the preferred range.
Examples of Warm Season Crops
Tomatoes
Peppers
Cucumbers
Squash (zucchini, butternut, etc.)
Eggplant
Okra
Watermelon
Cantaloupe
Pumpkin
Sweet potatoes
Corn
Beans (pole beans, lima beans, etc.)
Peanuts
Sunflowers
What Are Cool Season Crops?
Cool-season crops thrive in the moderate temperatures of fall and early spring.
These crops, including lettuce, spinach, carrots, and peas, possess unique attributes that enable them to flourish during the cooler months.
Characteristics of Cool Season Crops
Cool season crops tolerate temperatures within the range of 40-70°F (4-21°C) and often have a shorter growth cycle. They can endure light frosts and have rapid growth.
Requirements of Cool Season Crops
These crops thrive with well-drained soil, moderate sunlight (6-8 hours daily), and regular moisture. They can withstand cooler temperatures and even benefit from them.
Sowing Times for Cool Season Crops
Indoors: Begin around 6-10 weeks before the desired planting months, aligning with the end of summer or early fall.
In Zones 8-12, we can start many of these indoors or undercover during the late summer or early fall. Because of our mild winters, we can generally plant cool-season crops throughout the fall and winter, ending only in spring around late March.
Outdoors: Plan for direct sowing during the milder months of fall through early spring, avoiding extreme heat.
Examples of Cool Season Crops
Lettuce
Spinach
Kale
Broccoli
Cauliflower
Brussels sprouts
Cabbage
Carrots
Radishes
Peas
Swiss chard
Beets
Turnips
Onions
Garlic
What are Long-Season Crops?
Long-season crops encompass plant varieties that require an extended period to reach maturity and produce a harvest.
These crops demand a substantial growing season to develop fully, making them a strategic choice for gardeners in Zones 8-12 who have the luxury of extended warm weather.
Characteristics of Long-Season Crops
Long-season crops are marked by their slower growth rate and longer time to maturity. They often necessitate consistent warmth and a lengthy frost-free period to thrive.
Requirements of Long-Season Crops
These crops typically require well-draining soil, abundant sunlight, and regular moisture. The extended growing period allows them to develop deep root systems and produce bountiful yields.
Sowing Times for Long-Season Crops
Indoors: Start sowing seeds around 8-10 weeks before the projected planting months, aligning with the onset of the growing season.
You may need to pot these up after 6 to 8 weeks to provide adequate growing space.
Outdoors: Plan for direct sowing when the danger of frost has passed, and temperatures remain consistently warm.
Examples of Long-Season Crops
Tomatoes
Eggplant
Peppers
Melons (muskmelon, cantaloupe)
Winter squash (acorn, butternut)
Pumpkins
Sweet potatoes
Corn
Beans (pole beans)
Okra
What are Short-Season Crops?
Short-season crops are characterized by their ability to mature and yield within a shorter timeframe.
This often makes them quite suitable for the challenging subtropical conditions of Zones 8-12. Their fast growth rate allows you to get a harvest before it gets too hot or the pest pressure becomes overwhelming.
Characteristics of Short-Season Crops
Short-season crops have a quicker growth cycle, allowing them to complete their lifecycle before extreme weather conditions set in. They are often adaptable and can be grown as a reliable source of fresh produce.
Requirements of Short-Season Crops
These crops necessitate well-drained soil, moderate sunlight, and regular moisture. Their accelerated growth allows them to efficiently utilize available resources.
Seed Starting Times for Short-Season Crops
Indoors: Commence seed sowing approximately 4-6 weeks before the targeted planting months.
Because of their fast growth rate, it’s a good idea to sow seeds in succession. Planting another cell pack of seeds every two or three weeks allows you to plug in your small starters as space opens up in the garden.
You can use them for underplanting or filling in empty spaces. Or you can simply replace exhausted annuals in the garden.
Outdoors: Direct sow seeds when outdoor temperatures provide favorable conditions for germination and growth.
Again, succession seed starting is your friend. For many of these crops, you can direct sow in any empty spots in the garden for a quick harvest.
Examples of Short-Season Crops
Lettuce (leaf and butterhead varieties)
Spinach
Radishes
Carrots (early varieties)
Beets

Planning for Big Harvests and Garden Abundance.
Understanding the distinct characteristics and growth requirements of warm season, cool season, long-season, and short-season crops equips gardeners with invaluable insights for effective garden planning.
This knowledge empowers gardeners to make informed decisions on when to start your seeds, optimizing their gardening efforts for successful yields and a thriving garden ecosystem.
By applying this understanding, gardeners can:
Optimize Seed Starting Times
Gardeners can confidently initiate seed starting activities at the appropriate times, aligning with the unique temperature preferences of each crop.
This ensures that seedlings develop robustly and are ready for transplanting when outdoor conditions are favorable.
Maximize Space Utilization
Armed with knowledge of crop growth duration, gardeners can strategically allocate garden space to accommodate the varying needs of long-season and short-season crops. This efficient space utilization enhances overall garden productivity.
Extend Growing Seasons
Gardeners can take advantage of the subtropical climate in Zones 8-12 by two growing seasons by selecting a combination of warm season and cool season crops.
This enables continuous harvests throughout the year, capitalizing on both spring and fall gardening opportunities.
Plan Crop Successions
Understanding the distinct timelines for different crop types empowers gardeners to plan successive plantings. As one crop nears maturity, gardeners can prepare to replace it with a different crop, ensuring a constant supply of fresh produce.
Mitigate Climate Challenges
Knowledge of the climate-appropriate crops allows gardeners to navigate challenges posed by subtropical conditions. By choosing short-season crops during periods of extreme heat, gardeners can ensure a successful harvest without being adversely affected by temperature fluctuations.
Enhance Biodiversity
Gardeners can foster biodiversity by incorporating a mix of warm season and cool season crops, as well as long-season and short-season varieties. This diversity attracts beneficial insects, improves soil health, and promotes a balanced garden ecosystem.
Promote Soil Health
By strategically rotating warm season and cool season crops, gardeners can prevent soil depletion and maintain optimal soil health. Different crop types have varied nutrient demands, reducing the risk of nutrient imbalances.
Seed Starting Basics: How to Start Every Type of Seed
Starting seeds in seed tray cells, soil blocks, or individual pots is a practical and efficient way to kickstart your garden.
By starting them in a controlled environment, you can ensure that only healthy plant starts end up in your garden.
If you have little space to work with, seed starting in small containers is the most efficient way to use your limited garden space.
Starting Small Seeds
Small seeds, such as those of herbs and flowers, require special care during germination due to their delicate nature.
Follow these step-by-step instructions to ensure successful germination and healthy growth of small seeds in seed tray cells:
Step 1: Select the Right Seed Tray
Choose a seed tray with small individual cells. These cells provide ample space for each seed to germinate without crowding.
Step 2: Fill Seed Tray with Growing Medium
Fill the seed tray cells with a high-quality, sterile seed-starting mix. The mix should be light, well-draining, and rich in nutrients to support early seedling growth.
Step 3: Moisten the Growing Medium
Gently water the seed-starting mix until it is uniformly moist. Avoid overwatering, as excessive moisture can lead to seed rot.
Step 4: Sow the Small Seeds
Carefully sow one to two small seeds per cell, following the recommended planting depth for each seed type. Use a toothpick or tweezers to handle small seeds delicately.
If using old seeds or multi-sowing, you can drop two or three or four seeds per compartment.
Step 5: Cover the Seeds (Optional)
Some small seeds require darkness for germination, while others benefit from exposure to light.
Refer to seed packets or reliable gardening references to determine whether covering the seeds with a thin layer of vermiculite or seed-starting mix is necessary.
Step 6: Label the Seed Tray
Use plant labels to identify the seeds sown in each cell. Proper labeling ensures easy identification as seeds germinate and grow.
Step 7: Provide Bottom Heat (Optional)
To encourage germination, consider placing the seed tray on a heating mat or a warm surface. Bottom heat can improve germination rates for some small seeds.
This may be unnecessary in Zones 9-12, although you may want to start seeds indoors during the winter months to ensure consistent temperatures provided by your home heating system.
Step 8: Provide Adequate Moisture
Place the seed tray in a shallow tray filled with water to allow for bottom watering. Ensure that the seed-starting mix remains consistently moist, but not waterlogged.
Step 9: Cover the Seed Tray (Optional)
Cover the seed tray with a clear plastic dome or plastic wrap to create a mini greenhouse effect. This helps retain moisture and humidity for optimal germination.
Step 10: Place the Seed Tray in a Warm Location
Position the seed tray in a warm location with consistent temperatures suitable for germination.
A bright windowsill or indirect light on a covered porch can provide enough light for those that require light to germinate.
Step 11: Monitor Germination and Remove Cover
Keep a close eye on the seed tray for signs of germination. Once the seeds start sprouting, remove the cover to prevent mold growth and provide better air circulation.
For most plants, you’ll need to ensure that the new sprouts receive some light. Even seeds that require darkness to germinate will require sunlight once they’ve broken the surface.
Step 12: Thin Seedlings (If Needed)
If more than one seed germinates in a cell, gently thin the seedlings to leave only the healthiest one to grow.
You won’t want to do this if you’re multi-sowing, however.
Seed Starting for Large Seeds
Starting large seeds in soil blocks or pots provides ample space and nutrients for robust seedling development.
Large seeds, such as those of melons, cucumbers, and beans, benefit from a more substantial growing medium during germination. They grow so quickly that they’ll outgrow a smaller container before they’re ready to plant out.
Some plants benefit from up to three months of supervised cultivation before planting out, including tomatoes, peppers, and eggplant.
These long-season annuals are best planted once they’re well developed. To avoid stressing them with constant transplanting into larger containers, start with large soil blocks or small pots for germination.
Step 1: Choose the Right Containers
Select suitable containers for starting large seeds. Opt for individual pots or soil blocks with sufficient space to accommodate the size of the seeds and allow for root growth.
Step 2: Prepare the Growing Medium
Use a well-draining, nutrient-rich potting mix suitable for seed starting. Fill the containers with the growing medium, leaving about 1/2 inch (1.25 cm) space from the rim for easy watering.
Step 3: Water the Growing Medium
Moisten the potting mix thoroughly to ensure even moisture distribution. Avoid overwatering, as large seeds may rot in excessively wet conditions.
Step 4: Sow Seeds
Plant one large seed per pot or soil block. You can plant two per block when using old seeds.
Place the seed on top of the growing medium at the recommended planting depth for each specific seed type.
Step 5: Cover the Seeds
Cover the seeds with the recommended depth of soil mix.
Step 6: Label the Containers
Label each container or tray of soil blocks with the name of the plant variety to avoid confusion as the seedlings grow.
It’s also useful to add the date to your tags. This allows you to plan for succession crops based on the time to germinate.
Step 7: Provide Bottom Heat (Optional)
If starting in an unheated room during winter, using a heating mat or placing the containers on a warm surface encourages germination.
Step 8: Maintain Adequate Moisture
Keep the potting mix consistently moist by bottom watering the containers. Avoid overhead watering, which may dislodge the large seeds or create uneven moisture levels.
Step 9: Monitor Germination and Adjust Light
Keep a close eye on the containers for signs of germination. Once seedlings emerge, provide adequate light to ensure healthy growth.
Adjust the position of the containers to prevent leggy seedlings.
Step 10: Transplant Seedlings (If Needed)
As the seedlings grow, they’ll develop true leaves and become crowded in their pots. If the conditions in the garden aren’t optimal yet, consider transplanting them to larger containers or individual pots for further growth.
Step 11: Harden Off Seedlings
Before transplanting the seedlings outdoors, gradually expose them to outdoor conditions over several days. This process, called hardening off, prepares the seedlings for the change in environment.
How to Direct Sow Small Seeds in the Garden
Direct sowing small seeds in the garden allows for a natural and straightforward approach to gardening.
Whether you’re growing vegetables, herbs, or delicate flowers, direct sowing is the easiest method for many plant species.
I personally prefer seed starting in blocks or cells first, but if you’re establishing a wildflower meadow or looking to create large swathes of bedding annuals, direct sowing really is the most straightforward method.
Direct Sowing Small Seeds
Follow these step-by-step instructions to ensure successful germination and growth when direct seed starting small seeds in the garden:
Step 1: Choose the Right Location
Select a garden location that receives the appropriate amount of sunlight for the specific plant species you’re sowing. Consider factors like soil drainage and exposure to wind when choosing the site.
Step 2: Prepare the Soil
Clear the area of any weeds, rocks, or debris. Loosen the soil to a depth of about 2-3 inches (5-8 cm) using a garden fork or trowel. Rake the soil surface to create a smooth, level bed for sowing.
Adding a layer of compost or mixing some composted manure into the first inch or two of soil will help provide a good environment for your seeds to grow.
Alternatively, many wildflower seeds prefer poor soil condition, so don’t provide any garden amendments for these hardy troopers.
Step 3: Sow the Small Seeds
Gently sprinkle the small seeds evenly over the prepared soil surface. Follow the recommended planting depth and spacing for each seed type.
For very tiny seeds, mix them with fine sand or vermiculite to help distribute them more evenly.
Step 4: Cover the Seeds
Depending on the seed type, consider covering the seeds with a thin layer of fine soil, vermiculite, or compost. Some small seeds benefit from being exposed to light for germination, so do not cover them if indicated.
Step 5: Water the Seeded Area
After sowing, water the area gently to settle the soil and ensure good seed-to-soil contact. Avoid heavy watering, as it may dislodge the small seeds or cause them to clump together.
Step 6: Monitor Moisture Levels
Keep the seeded area consistently moist until germination occurs. Use a fine mist or a gentle watering can to avoid disturbing the seeds.
Step 7: Thin Seedlings (If Needed)
Once seedlings emerge and grow their first true leaves, thin them out if they appear crowded. This step ensures each seedling has sufficient space to develop properly. Consult the instructions on your seed packet for plant spacing.
Step 8: Mulch the Area (Optional)
Once seeds have germinated, been thinned, and have developed several sets of true leaves, consider applying a thin layer of organic mulch around the seedlings. This will conserve moisture, suppress weeds, and help to maintain an even soil temperature.
How to Direct Sow Large Seeds in the Garden
Direct sowing large seeds in the garden is a simple and efficient way to grow a variety of plants.
Although I generally recommend seed starting in blocks or cell trays and then planting out, species with deep tap roots, hypersensitive roots, or those that grow extremely quickly can be direct sown.
Whether you’re planting beans, squash, or sunflowers, follow these step-by-step instructions to ensure successful direct sowing of large seeds in your garden:
Step 1: Choose the Right Location
Select a sunny location in your garden with well-draining soil. Ensure that the chosen spot provides ample space for the large plants to grow.
If seed starting for climbers or vines, it’s a good idea to install your trellis or support structure before sowing your seeds.
This 1) prevents any damage done to delicate seedlings by trying to install the support after it has started growing. And 2) Allows you to better eyeball plant spacing by using the trellis or support as a measure.
Step 2: Prepare the Soil
Clear the area of any weeds, rocks, or debris. Decide where you’ll be planting each seed and cover each location with several inches of compost
If your soil is highly compacted, you can loosen the soil to a depth of about 4-6 inches in each location. We generally recommend no-dig methods and try to avoid disturbing the structure and living organisms below the soil surface.
Step 3: Sow the Large Seeds
Poke a hole to the depth recommended for the seeds and sow them directly into the prepared space.
Step 4: Cover and Firm the Soil
After sowing, cover over with the loose compost you provided. Firm the soil or compost over the seeds gently with your hands.
Step 5: Water the Seeded Area
Water the seeded area thoroughly after planting to help settle the soil around the seeds. Adequate watering is essential for proper germination.
Step 6: Monitor Moisture Levels
Keep the seeded area consistently moist until germination occurs. Regularly check the soil moisture and water as needed, especially during dry spells.
Step 7: Thin Seedlings (If Needed)
Once the large seedlings emerge and grow their first true leaves, thin them out if they are too close together. Thinning allows each seedling to have enough space to develop and access sunlight and nutrients.
Step 8: Feed and Mulch Your Plants
Once plants are a few inches high and have developed several sets of true leaves, you can apply vegetable fertilizer and mulch around the seedlings.
Consider applying a slow-release organic vegetable fertilizer or organic compost to support the growth of your plants. These once-a-month or once-a-season amendments can really save you many hours of hard work in the garden.
Water fertilizer or compost in well after application and then proceed to mulching.
Mulch can help retain moisture and keep the soil cool enough to support the beneficial microbiological organisms that plants need for healthy growth.
Consider straw or hay for mulching vegetable beds.
Wood chips are an excellent mulch for perennial plants, but don’t break down quickly enough for annual plantings and may interfere with your plants in future seasons.
Common Problems in Seed Starting, Prevention, and Remedies
Starting seeds can be a rewarding endeavor, but it is not without its challenges. Gardeners may encounter various problems during the seed starting process, leading to germination failure or stunted seedling growth.
Here is a list of common problems that may occur when starting seeds, along with their symptoms and remedies:
1. Problem: Poor Germination
Symptoms: Low percentage of seeds germinating or seeds failing to sprout.
Remedies: Ensure seeds are fresh and not expired. If you decide to use old seed up, double up on the number you plant.
Make sure the temperature is right for your seed type. You can find a chart of optimal temperatures on our website here.
You may have over-covered seeds that require light to germinate. Sometimes, seed packets lie and I’ve seen many that say to plant seeds ½ deep that won’t germinate without sunlight. Do some additional research on your seeds to be sure.
Avoid overwatering. This can cause seeds to rot before they can sprout.
2. Problem: Damping Off
Symptoms: Seedlings appearing weak, wilting, and collapsing at the soil level due to fungal infection.
Remedies: Use sterile potting mix and clean containers.
Improve air circulation around seedlings to reduce humidity.
Avoid overwatering and allow the soil surface to dry between watering.
3. Problem: Leggy Seedlings
Symptoms: Seedlings with elongated and weak stems reaching for light, often resulting from insufficient light or crowded conditions.
Remedies: Provide adequate light to seedlings, either with grow lights or by placing them in a sunny location. Thin out seedlings to allow ample space for each to grow.
In some cases, particularly tomatoes and peppers, you can salvage leggy seedlings by replanting them deeply into a larger container.
4. Problem: Seedlings Turning Yellow
Symptoms: Seedlings showing yellowing of leaves, usually due to nutrient deficiencies or overwatering.
Remedies: Although most seeds contain enough nutrients to support the initial growth of the seedlings, you may run into a nutrient deficiency if the seedling is in the cell too long.
You can use some dilute balanced liquid fertilizer when bottom watering.
To prevent this from happening, pot up your seedlings into larger containers sooner than later.
Yellowing may also be caused by overwatering. Bottom water with a very diluted fertilizer and allow the cells or pots surface to dry out before watering again.
5. Problem: Seedlings Growing Slowly
Symptoms: Seedlings not showing significant growth over time, possibly due to poor soil quality or low temperatures.
Remedies: Ensure the growing environment is warm enough to support seedling growth. Add a heat mat or move trays to a warmer location.
6. Problem: Fungal or Bacterial Diseases
Symptoms: Seedlings displaying discoloration, wilting, or lesions caused by fungal or bacterial infections.
Remedies: Remove affected seedlings promptly and destroy them.
Improve air circulation and avoid overcrowding to reduce disease spread. Use sterilized containers and tools.
Often, seed trays can show signs of algae growth on the tops. This is usually caused by exposure to sunlight when damp and is relatively harmless. The green sheen on top of your seed trays is annoying and unsightly, but it’s usually no detriment to the plant.
7. Problem: Insect Pests
Symptoms: Seedlings showing signs of pest infestations, such as chewed leaves or visible insects.
Remedies: Monitor seedlings regularly for pests and take appropriate measures, such as handpicking or using organic insecticides, to manage infestations.
If starting seeds outside, you may even find rodents digging into your seed trays to collect species like sunflowers, melons, or squash seeds. Cover seed trays with sturdy covers at night. You can also move them to a protected spot (like indoors) until they have sprouted to prevent this problem.
8. Problem: Lack of Hardening Off
Symptoms: Seedlings showing shock when transplanted outdoors due to insufficient acclimatization.
Remedies: Gradually expose seedlings to outdoor conditions for a few hours each day over several days before transplanting, a process known as hardening off.
If possible, transplant your young seedling during a cloudy day, especially if there’s rain in the forecast. I find this helps them transition to outdoor garden life much better.
9. Problem: Overcrowding
Symptoms: Seedlings growing closely together, leading to competition for resources and weak growth.
Remedies: It’s tough, but it has to be done. Thin out seedlings to provide adequate space for each plant to grow and develop.
10. Problem: Insufficient Watering
Symptoms: Seedlings showing signs of wilting or dry soil due to inadequate watering.
Remedies: Water seedlings consistently and ensure the soil remains evenly moist without becoming waterlogged.
FAQ
When is the best time to start seeds?
For successful seed starting in gardening Zones 8-12, there are generally two good times to start seeds. The first is four to six weeks before the last frost date in the spring for planting out in February and March. The second is in late summer in July and for planting out in September and October. This will vary depending on whether you’re planting warm season or short season crops.
Why should you start seeds indoors?
Starting seeds indoors in Zones 8-12 offers several benefits. It extends the growing season, giving delicate crops like tomatoes and peppers a head start before planting out. It also provides a controlled environment for germination, out of excessive heat and heavy rainfall.
Where is the best place to start seeds indoors?
In Zones 8-12, where warm and humid conditions prevail, the best location to start seeds indoors is a well-ventilated area with consistent warmth and ample sunlight. Choose a spot that receives abundant natural light or use grow lights. Be cautious not to overheat the seedlings. Adequate airflow is essential to prevent fungal issues, so ensure good ventilation while keeping the humidity in check.
How many seeds per starter pot should you sow?
When seed starting, it’s essential to strike a balance between providing adequate space for each seedling’s growth and maximizing your planting efficiency. Generally, aim to sow 2-3 seeds per starter pot, ensuring a higher likelihood of successful germination. If using old seeds from earlier seasons, consider sowing 3 to 4 seeds. This approach accounts for potential variations in seed viability and helps ensure at least one healthy seedling per pot. Once seedlings develop their first true leaves, you can carefully thin out the weaker seedlings, leaving the strongest ones to continue growing.
How many lumens for seed starting should a grow light have?
When using grow lights for seed starting, it’s important to provide your seedlings with the optimal amount of light to promote healthy growth. For most vegetable and flower seedlings, aim for a grow light that provides around 1000 to 1500 lumens per square foot. This light intensity mimics the brightness of natural sunlight and encourages sturdy stem development and vibrant leaf growth.
When do you begin starting fall seeds in Zones 8-12?
In Zones 8-12, the timing for starting fall seeds varies based on the type of seed you’re growing. In general, you’ll sow warm-season crops in late summer to plant out in the fall. You’ll sow warm-season crops again from late December through January to plant out after your last frost date.
For cool season crops, you can start seeds indoors in late summer and plant out from October through March as the weather allows. Most cool season crops can be planted in Zones 8-12 throughout the winter.
How many hours of light do seeds need to germinate?
Seeds require varying amounts of light for germination, depending on the plant species and its specific light preferences. In general, many seeds benefit from around 12-16 hours of light per day during the germination process. Remember that some seeds require darkness to germinate and should be covered or placed in a dark environment during this phase.
What are the 4 requirements for seed germination?
The four primary requirements for seed germination are water, proper temperature, oxygen, and suitable soil or growing medium. These factors work in conjunction to trigger the biochemical processes necessary for a seed to break dormancy, swell, and initiate growth.
Which seeds need light to germinate?
Seeds that require light for germination include lettuce, spinach, arugula, kale, radish, cilantro, dill, nasturtium, calendula, zinnia, sweet alyssum, and pansy. Providing these seeds with exposure to light during germination is essential for their successful sprouting and subsequent growth.
What not to do when germinating seeds?
When seed starting, it’s important to avoid overwatering, as excessive moisture can lead to fungal growth and rot. Additionally, refrain from planting seeds too deeply, as they may struggle to reach the surface. Avoid using contaminated soil, as it can hinder germination. Finally, placing seeds in an area with insufficient light or incorrect temperature can delay or prevent germination.
How do you know when a seed is germinating?
You can identify germination by observing the emergence of the seedling from the growing medium. As the seed absorbs water and swells, the outer shell cracks, and a tiny shoot, called the radicle, emerges. This initial growth is followed by the emergence of the seedling’s first leaves, called cotyledons.
How do you know if seeds are too old?
Seeds that are too old may exhibit reduced germination rates or fail to germinate altogether. You can assess seed viability by performing a simple germination test. Place a specific number of seeds on a damp paper towel, seal it in a plastic bag, and keep it in a warm location for the recommended time period. Afterward, count the number of seeds that have sprouted. If a significant percentage fails to germinate, it indicates reduced viability.
Which is the best seed starting mix?
We recommend a blend of coconut coir, perlite, compost, and a slow-release fertilizer that contains beneficial mycorrhizal fungi and beneficial bacteria. You can purchase a commercial blend like ProMix, or make your own. Avoid heavy garden soil or potting mixes, as they can impede seedling development.
How do I make my own seed starting mix?
A basic recipe includes mixing together coconut coir and perlite in equal parts. To make a larger batch, use a bucket or large container and thoroughly blend the ingredients until well combined. Optionally, you can add a small amount of finely screened compost or vermicompost for added nutrients. we also recommend adding a slow-release fertilizer for seed starting in small pots or soil blocks where the plants will remain for many weeks before planting out. This DIY mix offers a cost-effective and customizable solution for starting seeds, ensuring a suitable medium for germination and early growth.
What is a good recipe for soil block mix?
Mix the following components thoroughly to create a peat-free soil block mix. Coconut coir serves as an environmentally friendly alternative to peat moss, providing adequate moisture retention and aeration. It also adds structure to the soil block mix to ensure they hold together. Compost adds nutrients to support seedling growth, while vermiculite and perlite contribute to proper drainage and texture. This peat-free mix offers a sustainable option for starting seeds in soil blocks, promoting healthy germination and early development.
Bougainvillea (pronounced boo-guhn-VIL-yuh) is a stunning and vibrant flowering plant that originates from the tropical and subtropical regions of South America. Named after the French navigator Louis Antoine de Bougainville, who discovered the plant in Brazil during the 18th century, bougainvillea is now widely cultivated for its breathtaking display of color.
Bougainvillea is a vigorous and woody vine that can either climb or sprawl depending on its surroundings. It features glossy green leaves that are ovate in shape and slightly textured. The foliage provides a lush and verdant backdrop to the magnificent flowers that steal the show.
What we often perceive as bougainvillea’s flowers are, in fact, modified leaves called bracts. The true flowers of the plant are small and inconspicuous, nestled within the center of the bracts. These bracts come in a wide range of vibrant colors, including shades of pink, purple, red, orange, yellow, and white, creating a dazzling visual spectacle.
The showy bracts serve an important purpose for bougainvillea. They help attract pollinators like bees and butterflies to the true flowers concealed within. Once pollinated, the true flowers give way to small, inconspicuous fruit that contains tiny seeds.
Bougainvillea is perennial in mild climates, providing years of vibrant beauty to your garden. With proper care and maintenance, it can reach an impressive height of 15 to 30 feet and spread out over a similar distance, creating a sprawling and eye-catching display of color.

Ideal Growing Conditions for Bougainvillea
Bougainvillea thrives in hot and humid subtropical climates, making it an ideal choice for gardeners in the southern regions of the United States. It flourishes in regions with warm summers and mild winters, where temperatures rarely drop below freezing.
It is most commonly grown in USDA Hardiness Zones 9 through 11, encompassing areas such as the Gulf Coast, Southern Florida, and parts of California and Arizona.
To ensure the successful growth and blooming of your bougainvillea, it’s crucial to provide it with the optimal growing conditions. Here are the key factors to consider:
Type of Climate Required
Temperature
Bougainvillea thrives in temperatures between 60°F (15°C) and 90°F (32°C), with temperatures around 70°F to 85°F (21°C to 29°C) being ideal for growth and blooming.
It is important to protect the plant from freezing temperatures, as they can damage or kill it. If you live in an area prone to frost, consider growing bougainvillea in containers that can be moved indoors during colder months.
Temperature Tolerance
When temperatures consistently drop below 50°F (10°C), bougainvillea’s growth may slow down or temporarily cease. However, it can resume growth when warmer conditions return.
Temperatures below 32°F can cause damage to bougainvillea. Prolonged exposure to freezing temperatures can result in wilting, leaf discoloration, leaf drop, and damage to the stems and branches. In severe cases, it can lead to plant death.
Bougainvillea can tolerate high temperatures, but extreme heat, especially above 100°F, can stress the plant. It may result in wilting, scorched leaves, reduced blooming, and overall decline. Providing shade or ensuring adequate hydration during hot spells can help mitigate the effects of excessive heat.

Humidity
Bougainvillea appreciates moderate to high humidity levels, which are typically found in subtropical regions.
If you live in a drier climate, you can increase humidity around the plant by misting it regularly or placing a tray filled with water near the plant to create a humid microclimate.
Sunlight Exposure
Bougainvillea thrives in full sunlight. It requires at least 6 to 8 hours of direct sunlight each day to produce an abundance of colorful bracts. Choose a location in your garden that receives ample sunlight and is not shaded by trees or buildings.
Ensure you plant bougainvillea in a location with maximum exposure to sunlight.
Soil Type
Bougainvillea prefers well-draining soil that is rich in organic matter. Sandy loam or loamy soil is ideal for bougainvillea cultivation. If your soil is heavy or clay-like, consider improving its drainage and fertility by adding compost or well-rotted manure.
Bougainvillea thrives in slightly acidic to neutral soil with a pH range of 6.0 to 7.0. Conduct a soil test to determine the pH of your garden soil. If the pH is outside the preferred range, adjust it by adding amendments.
For increasing acidity, use elemental sulfur, and for increasing alkalinity, add dolomite lime.
When and How to Plant Bougainvillea
The best time to plant bougainvillea in the ground is during the warm months of spring or early summer when the soil has warmed up and all danger of frost has passed. This allows the plant to establish its roots before the colder months arrive.
However, if you live in a region with mild winters, planting can also be done in fall.
Planting Bougainvillea Step-by-Step
When you’re ready to plant your bougainvillea, follow these steps:
Find a Good Location
Choose a location in your garden that receives full sunlight and has well-draining soil. Ensure there is enough space for the bougainvillea to grow and spread comfortably.
Prepare the Soil
Amend the soil by incorporating organic matter such as compost or well-rotted manure. This helps improve soil fertility, drainage, and water-holding capacity. Remove any weeds or debris from the planting area.
Dig the Planting Hole
Dig a hole that is twice as wide and deep as the bougainvillea’s root ball. This allows the roots to spread out easily. Ensure the hole is deep enough to accommodate the entire root system without bending or crowding.
Remove the Plant from its Container
Gently tap the sides of the container to loosen the root ball. Carefully slide the plant out, holding it by the base of the stems.
Planting the Bougainvillea
Place the root ball in the center of the planting hole, ensuring the top of the root ball is level with or slightly above the soil surface.
Backfill the hole with soil, firming it gently around the roots to eliminate air pockets.
Watering and Mulching
After planting, thoroughly water the bougainvillea to settle the soil and encourage root establishment.
Apply a layer of organic mulch, such as wood chips or straw, around the base of the plant, leaving a small gap around the stems to prevent rotting.
Care and Maintenance of Bougainvillea
Once you’ve planted your bougainvillea, you’ll want to make sure it thrives.
Watering Throughout the Year
During the active growing seasons of spring and summer, water bougainvillea deeply and thoroughly, allowing the soil to dry out slightly between waterings. Aim to provide regular, consistent moisture without waterlogging the roots.
Reduce watering frequency during the dormant period around late fall through the winter. Water sparingly, allowing the soil to dry out more between waterings.
However, ensure the plant doesn’t experience prolonged drought stress, especially as temperatures begin to rise in February.
Optimal Fertilizer Composition and Schedule:
Fertilize your bougainvillea according to its stage of development and the needs of the season.
Spring
Use a balanced fertilizer with equal NPK (nitrogen, phosphorus, potassium) ratios or a slightly higher nitrogen content.
Apply the fertilizer every 4 to 6 weeks during the active growing season.
Summer
Switch to a bloom-boosting fertilizer with a higher phosphorus content to promote abundant flowering. Apply every 6 to 8 weeks.
Fall and Winter
Reduce or suspend fertilization during the dormant period. Bougainvillea generally requires less fertilizer during this time.
Follow the instructions on the fertilizer package for specific application rates and guidelines. Then, adjust fertilization based on the plant’s response and the quality of your soil.
Protecting Bougainvillea from Cold
Even though we can grow tropical plants, we can still get the occasional cold snap in Florida and in states around the Gulf Coast.
Our normally mild winters can even mean that a cold snap is that much more devastating to plants that aren’t equipped to deal with them.
How you protect your bougainvillea will vary depending on how long the cold snap is predicted to last.
Watering
If you’ve lived in Florida for any length of time, you know how insane our weather can be. In the winter, for example, the temperature during the day could be 85°F and then sink to 38°F during the night, usually with the lowest temperature right before sunrise.
This happens several times a year in Central Florida, sometimes in December, but usually in January and February.
If the forecast is for a brief overnight cold snap, you should water your bougainvillea well during the warmth of the day prior.
The moist ground will store the warmth of the sun during the day, carrying through the night. So, make sure you water as early as possible to make the most of the sunlight.
If the cold period is predicted to last through daylight hours or last for several nights, excess moisture in the soil is a bad thing. So, in that case, do not water your bougainvillea during cold days or when it will be below 40°F for several nights in a row.
Whether your water or not, it’s a good idea to apply a thick layer of organic mulch around the base of the plant, extending it to cover the root zone. This helps insulate the soil and protect the roots from extreme cold.
Covering
Before the arrival of frost or freezing temperatures, cover the bougainvillea plant with a frost blanket or horticultural fabric. Secure the cover to the ground to create a protective barrier against cold winds.
I generally try to cover my plants well before sunset and the warmth of the day fade.
Container Plants
If you have bougainvillea in containers, move them to a sheltered location, such as a garage or greenhouse, during periods of freezing temperatures.
Pruning Bougainvillea for Optimal Growth and Shape
Pruning bougainvillea is essential for maintaining its shape, encouraging healthy growth, and promoting abundant flowering. Here’s a guide on how and when to prune your bougainvillea:
Timing of Pruning:
The best time to prune bougainvillea is during late winter or early spring, just before new growth begins. This timing allows the plant to recover and produce new shoots and blooms during the active growing season. However, minor pruning to remove dead or damaged branches can be done throughout the year. You may also need to prune it to keep it under control.
Tools Needed:
Pruning shears or sharp bypass hand pruners
Gardening gloves
Loppers or a pruning saw for thicker branches (if necessary)
Disinfectant solution (such as rubbing alcohol or bleach) to sterilize your pruning tools (before and after use) to prevent the spread of diseases.
The Pruning Process
Pruning bougainvillea while avoiding the thorns.
Follow these steps to prune your bougainvillea effectively:
Step 1: Assess the Plant:
Observe your bougainvillea and identify the branches that need to be pruned. Look for dead, damaged, or diseased branches, as well as any overly long or unruly growth that needs shaping.
Step 2: Prepare Your Tools:
Ensure your pruning tools are clean and sharp. Sterilize them with a disinfectant solution to prevent the spread of diseases from one plant to another.
Step 3: Prune Dead or Damaged Branches:
Start by removing any dead, damaged, or diseased branches. Make clean cuts just above a healthy bud or side branch, using sharp pruning shears. Cut at a slight angle to allow water to drain off the wound.
Step 4: Control the Plant’s Size and Shape:
To maintain the desired size and shape of your bougainvillea, selectively prune long or unruly branches. Identify branches that are extending beyond the desired boundaries or obstructing walkways, fences, or structures. Make pruning cuts just above a bud or side branch, leaving a stub of the branch to promote new growth.
Step 5: Thinning Out the Canopy (Optional)
If your bougainvillea is dense and overcrowded, you may consider thinning out the canopy to improve airflow and light penetration. Remove some of the interior branches to open up the plant and reduce the risk of pests or diseases.
Step 6: Clean Up and Disinfect:
After pruning, gather and remove the pruned branches and debris from the area. Dispose of them properly. Clean and disinfect your pruning tools with a sterilizing solution to prevent the spread of diseases.
Step 7: Post-Pruning Care:
After pruning, water your bougainvillea thoroughly to help it recover and encourage new growth. Apply a balanced fertilizer to provide the necessary nutrients for the plant’s recovery.
Remember, bougainvillea blooms on new growth, so avoid excessive pruning that removes too many potential blooming branches. Pruning should focus on maintaining the plant’s shape, removing dead or damaged branches, and promoting healthy growth.

Common Pests, Diseases, and Special Care for Bougainvillea
Bougainvillea, like any other plant, can be susceptible to certain pests, diseases, and specific care requirements. Here’s a breakdown of common pests, diseases, and special care for bougainvillea:
Common Bougainvillea Pests
Aphids
Aphids are small, soft-bodied insects that feed on plant sap, causing leaves to curl, yellow, or become distorted. To remedy aphid infestations, you can:
Spray a strong stream of water on the affected plant parts to dislodge the aphids.
Apply insecticidal soap or horticultural oil following the product instructions.
Introduce natural predators like ladybugs or lacewings to control aphid populations.
Caterpillars
Caterpillars, such as the bougainvillea looper or cabbage looper, can chew on leaves, causing significant damage. To remedy caterpillar infestations, you can:
Handpick and remove caterpillars from the plant.
Apply Bacillus thuringiensis (Bt), a biological insecticide that targets caterpillars.
Use insecticidal sprays labeled for caterpillar control, following the product instructions.
Whiteflies
Whiteflies are tiny, sap-sucking insects that cluster on the undersides of leaves, causing yellowing, leaf drop, and a sticky residue called honeydew. To remedy whitefly infestations, you can:
Use yellow sticky traps to capture adult whiteflies.
Spray the affected foliage with insecticidal soap or horticultural oil, ensuring thorough coverage.
Encourage natural predators like parasitic wasps or ladybugs to control whitefly populations.
Common Bougainvillea Diseases

if you’re a Florida gardener, not just any gardening YouTuber will give you the information you need. Florida is so weird, the Farmer’s Almanac print version actually has an entirely separate section devoted to our whacky planting schedule. Gardening in Zones 9-11 is difficult enough, but gardening on the Gulf Coast is just “special.” What you need is Florida gardening YouTube video channels.
Gardening channels on YouTube have really exploded over the last five years. Many of my favorite YouTubers have gone from tiny suburban gardens to purchasing big ol’ homesteads. And I’m guessing that the popularity of their channels has a lot to do with that.
But which Florida gardening YouTube channels are the best? Which of the many garden YouTubers really, TRULY understands the struggle of gardening in the Gulf Coast region?
Because the struggle is real.
While the rest of the country watches their sweet corn reaching for the clouds, we’re hiding inside behind hurricane shutters.
While temperate climate gardeners are dumping zucchini anonymously on doorsteps throughout their neighborhoods, we’re tossing the blackened, shriveled stumps of our failed summer squash into the compost heap.
Again.
Many of us have turned to YouTube for help and instruction.
If you’re new to gardening in Florida or new to YouTube garden videos, I’m happy to help you find the best Florida gardening YouTube channels. As much as I love classic shows like PBS’s Victory Garden and BBC’s Gardeners World, let’s face it: very little of the content on either show has anything to do with Zone 9-11 gardening.
So, Which Are the Best Florida Gardening YouTubers?
The best YouTubers all have their own special gifts and perspectives to add to the conversation. So, I’ll start with my top choices, and you can decide who your own favorites are.
Here is a list of my favorites that I’ve been watching over the last four or five years. While not all of them are specifically for Florida, much of their content is relevant to our interests. They’re on the Gulf Coast or garden in a subtropical climate.
7. Wild Floridian
I can’t believe it took me so long to find “Wild Floridian” on YouTube. After all, like me, the presenter is in Zone 10A, and I think she lives a few miles away. So, naturally, she’s a great source of super-local information for me and anyone else living in Central Florida along the coast.
Jacqueline focuses a lot on gardening for pollinators, so she has tons of videos about native Florida plants. And her extensive knowledge isn’t just academic. Her videos are a serious deep-dive demonstration of how to use them in your landscape.
She’s only been on YouTube since 2019, but it’s obvious that she knows a lot about gardening in this region. She’s my top choice when it comes to information on gardening in Florida for wildlife.
6. The Urban Harvest
Elise of Urban Harvest in the Tampa Bay area knows what she’s talking about. While her YouTube channel doesn’t offer a plethora of videos, she also offers more information on her website.
She also has a seed club that sends you seeds for plants that are timed right for our unusual growing cycles. She also offers classes on garden planning, composting, and other topics.
Elise is one of the few Florida gardening YouTubers that really understands how to work with our wonky seasons and unique (i.e. humid) conditions. She’s also extremely knowledgeable about those little-known alternative vegetables and herbs that grow easily here.
When I first reviewed The Urban Harvest on this blog, Elise only had a few dozen videos on YouTube. Now, she has over 100. Most are short and to the point, which I think is a positive attribute when I’m looking for information.
5. Scott Head / Black Gumbo
Sometimes, the best Florida gardening YouTube channels aren’t run by Floridians. In this case, Scott Head lives in Coastal Texas, along the Gulf, in Zone 9a. So, he has a good idea of what kind of climate and growing calendar we use in Florida.
You’ll find many seasonal videos covering all things edible in the garden, plus some great instructionals on how to cook those things. His blog goes back even further, should you prefer reading to viewing. Sometimes, you just need the deets and don’t have time for chit-chat or garden tours.
He offers an extensive library of information videos about Southern gardening, cooking, and even preserving food. Extra credit for backyard chicken videos.
Southerners are pretty laid back, and sometimes Scott can be a bit too laid back if you’re in a hurry to get answers. But honestly, it’s a nice change of pace from some of the more frantic garden YouTubers I’ve seen.
4. The Millenial Gardener
Another one of my favorite not-Florida gardening YouTube channels with useful info. This YouTuber (can’t find his name anywhere) lives and gardens in 8a on the coast of North Carolina, so definitely subtropical, and definitely a hot & steamy Southern climate.
You’ll certainly learn a lot on this channel. The Millenial Gardener offers tons of tips and hacks for dealing with the downside of gardening in the South. Hacks for heat, humidity, bugs, and disease. His presentation style is simple and scientific, with demonstrations and explanations of how and why they work.
I’ve tried a few of his trick over the last year or two, and every single one has been a winner.
3. Pete Kanaris / GreenDreamsTV
Pete’s nursery and landscaping service, GreenDreams, sits north of Tampa. Along with an extensive array of edible and permaculture-friendly plants, GreenDreams also offers design and installation services.
However, the best thing about Pete’s YouTube channel is that you’ll become inspired. Pete shares his experience of subtropical and tropical edible plants and explains their unique flavors and growing needs. You’re going to want half a dozen of whatever he’s talking about by the time the video is over.
Pete’s a professional plantsman with specialized knowledge of unique and unusual edible and beneficial plants for a Florida landscape. Probably the most knowledgeable Florida gardening YouTube channel you’ll find.
However, you won’t find much about growing the common zucchini on Pete’s channel, although occasionally, he’ll visit with a market gardener, Joe Kowaleski, who grows them. The two have teamed up to produce a vegetable garden masterclass, but it’s pretty expensive unless you’re going pro.
2. Mark Valencia / Self-Sufficient Me
Another great Florida gardening YouTube channel that isn’t filmed in Florida at all — not even close! Mark’s a stay-at-home dad from Australia. But even though he gardens on the other side of the planet, he also gardens in a subtropical climate. Many of the edible fruits and veg you’ll see him plant are the same ones that grow here in Florida.
And believe it or not, he’s got even more intimidating pests than we have!
Mark’s website also features a lot of great information if you’d prefer to read up. He also has an active user forum for sharing information with other gardeners.
Mark’s super knowledgeable about growing in a subtropical and tropical climate without being too academic or pedantic. Mark is as entertaining to watch as he is informative. His relaxed and somewhat hokey style is just what’s called for if you need low-stress gardening entertainment.
Keep in mind that, even though Mark’s climate is very similar to ours, it’s still on the other side of the planet. That means that if you want information for our current season, you need to search back on his channel about six months to find the relevant information.
1. David the Good (Goodman)
I’ve been reading David’s Survival Gardener blog for several years and have even purchased many of his Florida-specific gardening books. But it took the pandemic for me to discover that he also has a YouTube channel. (Granted, it took the pandemic to get me back to YouTube after Vevo took over music videos.)
David’s irreverent humor is obvious in his written work, and it carries over into his videos. His specialty is “survival gardening,” which we can assume means information for preppers when the SHTF. And although he does provide a lot of good prepper info, it’s also excellent information for those of us who simply want to be more sustainable. Sustainable is better for the earth, and it’s cheaper, too. What’s not to love?
Because of his many years of experience, wry style, and deep dives into growing on the cheap (and natural), David gets my vote as the single best Florida gardening YouTube channel to watch. Even though he now lives in Alabama.
David is fun to watch. He provides plenty of actionable information for any type of vegetable gardener, but his wit is much appreciated. His gardening experiments are especially helpful. He always seems to have plenty of land to play with new methods and new crops.
Who Are Your Favorites?
Those are my top picks for the best Florida gardening YouTube channels to watch. More specifically, they’re my top five picks for Florida gardeners, since not all of the Tubers involved are in Florida.
If you have a favorite Florida-specific gardening channel on YouTube, please let me know. I’m always interested to see what else is available on the platform.
If you’ve been paying attention to the weather forecast, it’s likely that the last thing on your mind is what to plant in July in Florida. The heat indexes have easily been in the triple digits, and the rainfall reports are way down.
The good news is that if you’re just as addicted to gardening as I am, there are a few things you can do to feed that urge, even in all this heat.
That’s right, Florida gardeners — it’s July! It’s not time to get back into the garden quite yet, but it IS time to start collecting supplies and sowing seeds indoors and under cover.
It’s time to get ready for the fall garden. Start stocking up on your favorite seeds and get cracking. It’s go time.
It’s Time to Get Seeding!
We had a ridiculously cold winter and a frighteningly dry spring. It’s even been a dry summer.
While you may have given up on your tomatoes months ago, you can certainly try again now.
While you can grow nearly anything between September and December in Florida (at least Central and South Florida), the time to start long-season crops is right now.
Tomato Time
Start tomato seeds in mid-July through Mid August in order to plant out into the garden or containers in September.
You’ll want to be sure that the temperatures have dropped low enough that tomatoes can flower and form fruit, so keep an eye on the weather.
The best way to be ready to have well-developed plants to add to the garden as early as feasible is to start them indoors in July.
You can grow your seedlings under cover and pot them up as they grow for up to three months if necessary. In containers, you can better control their exposure to scalding sun and downpouring rains.
We’ll be selling a new line of vegetable starters suited for Florida gardens in our nursery. If you’re not nearby, we invite you to check out our seeds for sale. We’ve curated the best varieties for the hot & humid Southeastern states, Gulf Coast region, and blistering hot Southwest garden.
And all of our tomato seeds come with a free pack of companion French Marigolds, because we know the tragedy that is root knot nematodes.
Peppers
Everyone loves peppers because they’re easy to grow, come in a wide variety of colors, and have different flavor profiles for a range worldwide cusines.
But boy, can they be lazy.
Peppers can take forever to take off. I don’t know how many times I’ve stared pointedly at cell trays of peppers wondering whether to even bother misting them after two weeks.
Because they do take some time to get going, start them now so you’ll have time to plant them out as early as possible.
They don’t like the cold at all, so if we get another chilly December, it will be nice to get some sweet bells before then.
Check out our California Wonder pepper seeds to plant in July in soil blocks or cells.
Protecting Your Seedlings
Sowing under cover in Florida isn’t an issue of protecting delicate seedlings from the cold. Here, it’s a matter of preventing them from getting washed out by heavy rainstorms.
Starting seeds out of the elements can help keep them from burning up when the heat index is in the triple digits and even your hot peppers are getting scalded.
Whether you start them on a patio, lanai, or indoors, make sure they get plenty of light once the seeds germinate.
Since the long-season peppers and tomatoes like to germinate in warm temperatures, keep your seed starting trays somewhere where they’ll stay at a minimum of 75°F.
They’ll also need some airflow, which not only reduces the chance of dampening off but also stimulates the growth of strong, sturdy stems.
What Else to Plant in July in Florida?
Along with starting your Fall crops by seed, there are also a few heat-loving veggies you can direct sow. Summer is great for planting Okra and Southern Peas. If you’re not a big fan of black-eyed peas or cowpeas, you can also sow them as cover crops to improve your soil for fall planting out.
If you’ve already sown or purchased starts of tropical vegetables or Mediterranean herbs, you can add them to your garden. You’ll find exotic veggies like Okinawa spinach or Longevity spinach at many Florida nurseries. We sell Okinawa spinach starts too.
Make sure your Mediterranean herbs have plenty of drainage, as they can get root rot from our persistent (and seemingly unending) rainfall.
And don’t forget to plant flowers! Many annual flowers you can add to the garden will attract pollinators and beneficial insects that help nurture and protect your crops. Some will grow and bloom in just 60 to 75 days. Quick-growing annual flowers add beauty and diversity to your garden, and many provide critical root exudates for your soil.
Start your broccoli and tomato plants in late July in Central and South Florida.
Here’s what you can start sowing in July in Florida, as well as other Gulf Coast states in the U.S>
South Florida (Zones 10 to 11)
If you’re in South Florida, and some parts of coastal Central Florida, the weather is steaming, even dangerous.
However, it changes fast, so it’s a good idea to be ready with healthy vegetable plants starts so you’re ready to plant out in September.
Scarlet Sage loves the heat and will draw in bees and hummingbirds to your garden.
Pace Yourself When Gardening in Florida in July
Don’t try to start everything at once. Remember, it’s still very hot out there, and it looks like it will stay dry. So, no regular summer storms to cool things off a bit. There’s still a risk of heat exhaustion and skin damage from UV rays.
The wonderful thing about gardening in Florida is our mild autumn and the length of our growing season. Start with vegetables that take the longest time to mature, such as tomatoes and peppers. In Central and South Florida, you can usually plant these out as late as October and overwinter them by covering them on cold nights.
I’m never happy to see the days get shorter, but I’m always excited for the Fall gardening season. To make the most of it, you can get many of your vegetables and flowers started in July.
Perpetual spinach chard is a rare leafy vegetable that thrives in subtropical climates. With its rich heritage and impressive adaptability, this hardy plant is a must-have for gardeners residing in warmer zones 9 through 11.
Perpetual spinach chard, scientifically known as Beta vulgaris subsp. cicla var. cicla ‘Perpetual Spinach’, belongs to the beet family. It is believed to have originated in the Mediterranean region, where it was cultivated for centuries. This versatile vegetable has a long history of culinary use, with its origins dating back to ancient Greek and Roman times.
Perpetual Spinach Chard Plant Details
Perpetual spinach chard features large, tender leaves that are glossy and dark green, similar to true spinach but with a slightly thicker texture. The leaves grow on sturdy, succulent stalks.
The plant has a biennial growth habit, although it is often cultivated as an annual in cooler climates. It typically reaches maturity within 55 to 60 days from sowing. When fully grown, this leafy vegetable forms a compact rosette of lush foliage, reaching a height of about 12 to 18 inches and spreading approximately 12 inches in width. Its compact size makes it an excellent choice for container gardening as well.
Where and When to Grow Perpetual Spinach
For gardeners residing in the U.S. perpetual spinach chard thrives in subtropical regions with warmer climates. Specifically, it performs exceptionally well in USDA Hardiness Zones 9 through 11. The milder winters and longer growing seasons found in these areas create the perfect conditions for this robust leafy green.
Optimal Growing Conditions for Perpetual Spinach Chard
For the best results and the most abundant harvest, keep the following factors in mind.
Temperature
Perpetual spinach chard thrives in moderate temperatures, preferring a range between 60°F and 80°F. However, it is very heat tolerant and will tolerate cold snaps down to 32°F. Growth will slow during extreme heat and cold.
Humidity
The plant prefers moderate humidity levels. While it can tolerate higher humidity, it is important to provide good air circulation to prevent fungal diseases.
Sunlight
Perpetual spinach chard requires full sun to partial shade, with a minimum of 4 to 6 hours of direct sunlight each day. In hotter regions, providing some afternoon shade can help prevent wilting or scorching of the leaves. It’s suitable for shady patches of the garden in subtropical zones.
Soil Type
It thrives in well-drained, fertile soil rich in organic matter. It prefers a slightly acidic to neutral pH level between 6.0 and 7.0. Amending the soil with compost or well-rotted manure before planting will help provide the necessary nutrients and improve soil structure.
Planting Times
Since perpetual chard acts as a perennial edible plant in subtropical zones, you can plant it nearly any time of year. However, avoid planting out during the hottest or coldest times.
For spring planting, start indoors up to 8 weeks before the last frost date and plant out once that date has passed.
In the summer or fall, start seeds indoors, and plant out once the plant has fully developed (about 8 weeks). For best cold resilience, sow and establish at least one month before the first frost date.
Starting Perpetual Spinach Chard Seeds
We recommend starting perpetual chard seeds in cell trays or soil blocks. This allows you to plant out a healthy, well-developed young plant that is more resistant to pests and disease.
Fill cell trays or soil blocks with a high-quality seed-starting mix, moistening it slightly before planting.
Sow the seeds about ¼ to ½ inch deep.
Place the trays or blocks in a warm location with temperatures around 70°F to 75°F.
Maintain consistent moisture by misting the soil surface or using a bottom-watering technique.
Germination typically occurs within 7 to 14 days.
Once the seedlings have developed their second set of true leaves, you can transplant them into the garden. However, we recommend planting out once the plant is 6” and has developed several sets of true leaves. This ensures it will better survive transplant shock or environmental pressures.
Transplanting Perpetual Spinach Chard
Once you have healthy young seedlings, you’ll want to transplant them into your garden or into a larger container.
Into Garden Beds:
Choose a well-prepared garden bed with loose, amended soil.
Dig holes that are slightly larger than the root ball of the seedling.
Gently remove the seedlings from the module cell or soil block tray, taking care not to damage the roots.
Place the seedlings into the holes and backfill with soil, firming it gently around the base of the plants.
Space the plants 8 to 12 inches (20 to 30 cm) apart to allow sufficient room for growth.
Water the newly transplanted seedlings thoroughly to help them establish.
Into Containers:
Select containers that are at least 6 to 8 inches deep to accommodate the root system.
Fill the containers with a well-draining potting mix, leaving about an inch of space below the rim.
Gently remove the seedlings from the cell trays or soil block trays, being careful not to disturb the roots.
Place the seedlings in the center of each container and fill in the remaining space with potting mix.
Water the containers thoroughly until excess water drains from the bottom.
Temp Tolerance for Perpetual Spinach
Perpetual chard may require some extra care when the weather is extreme.
Protect from Excessive Heat
High temperatures above 95°F can cause the leaves to wilt, scorch, and lose flavor. Providing shade or mulching can help protect the plants during extreme heat.
Protection from Cold
To protect perpetual chard from a deep cold snap, apply a layer of mulch around the base of the plants to insulate the roots and conserve moisture. Cover the plants with row covers or frost blankets during freezing temperatures.
Watering Schedule
During the winter and spring, water the plants deeply once or twice a week, ensuring the soil remains consistently moist but not waterlogged.
During the summer and fall, water as needed to provide moisture if it doesn’t rain adequately.
Fertilizer Composition and Schedule
Prior to planting, incorporate compost or well-rotted manure into the soil for nutrient enrichment.
During the growing season, apply a balanced organic fertilizer or a slow-release granular fertilizer according to the package instructions every 4 to 6 weeks.
Avoid excessive nitrogen fertilization, as it can promote leafy growth at the expense of root development. Opt for a balanced fertilizer instead.
Common Pests
Perpetual spinach chard may be subject to a few pests.
Aphids: Use a strong blast of water or insecticidal soap to control aphid infestations.
Slugs and Snails: We recommend Sluggo baits, which are very effective, very affordable, and certified OMRI for organic use.
Leaf Miners: Remove infested leaves and destroy them to reduce leaf miner populations.
Caterpillars: Handpick caterpillars or use organic insecticides labeled for vegetable use. We recommend products containing a naturally occurring bacteria called Bacillus thuringiensis (or bt for short), such as Thuricide.
Similar products that contain Spinosad are also organic and are affective against a wider range of pest insects, including aphids. Monterey’s Spinosad is an excellent choice.
Common Diseases
Downy Mildew: Ensure good air circulation, avoid overhead watering, and apply appropriate fungicides if necessary.
Leaf Spot: Remove affected leaves and practice good sanitation to prevent the spread of the disease.
For significant infections, we recommend applying an organic copper spray after removing the affected foliage.
Powdery Mildew: Improve air circulation, avoid overhead watering, and apply fungicides labeled for powdery mildew control. Apply a mixture of 8 Tbs of household hydrogen peroxide (3%) mixed with one gallon of water with a sprayer every three days for a week or two for an inexpensive organic fungicide against powdery mildew.
Regularly monitor your plants for any signs of pests or diseases and take prompt action to prevent damage or spread.
Special Needs and Care for Perpetual Spinach Chard
Thinning: When sowing directly, think seedlings when they reach a height of about 2 to 3 inches to ensure proper spacing between plants. Remove the weaker seedlings, leaving the healthiest and strongest ones to grow. These plants grow best when spaced at around 12”.
Mulching: Apply a layer of organic mulch around the base of the plants to help conserve moisture, suppress weed growth, and regulate soil temperature.
Companion Plants for Perpetual Spinach
Perpetual spinach chard can benefit from companion planting, which involves growing compatible plants in close proximity to enhance growth, deter pests, and promote overall garden health. Here are some suitable companion plants for perpetual chard:
Herbs
Plant aromatic herbs like basil, dill, parsley, and cilantro near perpetual spinach chard to repel pests and attract beneficial insects.
Nasturtiums
Nasturtiums serve as sacrificial plants, attracting pests like aphids away from perpetual chard.
Harvesting Perpetual Spinach
Regularly harvest outer leaves when they reach a size of about 6 to 8 inches long. This will encourage continuous growth and prevent the plants from bolting.
If the plants start to bolt (produce flower stalks), it is best to remove them to maintain quality. Alternatively, you can allow them to flower for your bee population and to collect seeds once matured.
Perpetual chard can be harvested as soon as the outer leaves reach a desirable size. Here’s how to harvest:
Select the outer leaves, starting with the largest ones, leaving the smaller inner leaves to continue growing.
Use a sharp knife or scissors to cut the leaves off at the base, or you can gently twist and pull them from the stem.
Harvest regularly to encourage new leaf growth and a continuous harvest throughout the growing season.
Cooking with Perpetual Spinach
Perpetual spinach chard is a versatile leafy green that can be enjoyed in various culinary creations. Here are some cooking and meal ideas:
Fresh Salads
Use young and tender leaves as a nutritious base for salads. Mix with other greens, add your favorite toppings, and dress with a light vinaigrette.
Sautéed or Stir-Fried
Heat olive oil or butter in a pan, add chopped leaves, and sauté with garlic, onions, or other vegetables for a flavorful side dish. Stir-frying with soy sauce and sesame oil also creates a delicious Asian-inspired dish.
Quiches and Frittatas
Add cooked and chopped leaves to quiches, frittatas, or egg muffins for a nutrient-packed and flavorful meal.
Soups and Stews
Incorporate into soups, stews, or hearty winter dishes for added nutrition and a vibrant green color.
Wraps and Sandwiches
Use large perpetual spinach chard leaves as a substitute for tortillas or bread in wraps and sandwiches for a healthy and low-carb option.

Choosing a Location
Select a site that receives full sun to partial shade, ensuring at least 6 hours of direct sunlight per day.
Consider the plant’s mature size and provide enough space for it to grow without overcrowding nearby plants or structures.
Ensure the planting location has well-draining soil to prevent waterlogging.
Step-by-Step Instructions for Planting a Duranta erecta Plant:
Dig a hole: Dig a hole that is twice the width and slightly deeper than the root ball of the Duranta erecta plant.
Prepare the soil
If the soil is heavy clay or lacks organic matter, mix in compost or well-rotted manure to improve drainage and fertility.
Remove the plant from its container
Gently tap or squeeze the container to loosen the root ball, then carefully slide the plant out.
Position the plant
Place the plant in the center of the hole, ensuring that the top of the root ball is level with or slightly above the soil surface.
Backfill the hole
Fill the hole with the amended soil, gently firming it around the root ball to eliminate air pockets.
Water thoroughly
Give the newly planted Duranta erecta a deep watering to settle the soil and establish good root-to-soil contact.
Aftercare
Provide regular watering, keeping the soil consistently moist but not waterlogged, especially during the first few months after planting.
Apply a layer of organic mulch around the base of the plant, keeping it a few inches away from the stem. Mulch helps conserve soil moisture and suppress weeds.
Watering Schedule
Duranta can be a thirsty plant, so consider the weather and temperature when deciding how frequently to water your plant.
Spring: Water thoroughly and regularly as new growth emerges.
Summer: Increase watering during hot and dry periods to ensure adequate soil moisture.
Fall: Maintain regular watering as the plant prepares for winter.
Winter: Reduce watering, allowing the soil to dry out slightly between waterings.
Optimal Duranta Fertilizer Composition and Schedule
To make the most of your fertilizer dollars, make sure you feed your Golden Dewdrop appropriately throughout the year.
Leafing Out (Spring)
Use a balanced slow-release fertilizer, such as a 10-10-10 or 14-14-14. Apply according to the package instructions, typically in early spring when new growth begins. Follow recommended rates based on the size and age of the plant.
Blossom (Summer)
Switch to a fertilizer higher in phosphorus, such as a 10-20-10 or 15-30-15. Apply as directed on the package during the active blooming period to support flower production and quality.
Pre-Winter/Over Winter
Avoid fertilizing during late fall and winter when the plant enters a period of dormancy. Instead, focus on providing adequate moisture and protecting the plant from cold temperatures.
Placing a thick layer of compost or other organic matter under the mulch to break down over winter will provide better growing conditions in spring.
Note: It is crucial to follow the specific instructions provided by the fertilizer manufacturer and adjust the amounts based on the plant’s needs and growing conditions.
There are a few pests that might make a meal of your Golden Dewdrop. Remember that you don’t have to remove them if you choose not to. Many of these pests provide food for wildlife, so you may want to refrain from treatment unless they threaten the life of your plant.
Aphids
These small, soft-bodied insects cluster on new growth, sucking sap from the plant. Use a strong jet of water to dislodge them and let ladybugs feast on the rest.
It’s also a good idea to look for ants if you see an aphid infestation. Ants will protect aphids from predators in order to farm them for their “dew.”. An ant trap with boric acid will reduce the number of ants and aphids in an environmentally friendly way.
Whiteflies
These tiny, white insects congregate on the undersides of leaves, causing yellowing and stunted growth. Remedy: Use insecticidal soap, neem oil, or introduce natural predators like ladybugs or lacewings.
Caterpillars
Various caterpillar species, such as the caterpillars of the Gulf Fritillary butterfly, can feed on the leaves. We recommend handpicking them, but only if they seem to be a real threat to your Duranta erecta plant.
Note that Oleander moth caterpillars may also infest your Duranta plant and become devastating. Unfortunately, it is easy to confuse them with Gulf Fritillary caterpillars.
Spider Mites
These tiny pests cause yellow stippling on leaves and produce fine webbing. Spray the foliage with a strong jet of water to dislodge them or apply insecticidal soap or horticultural oil. Spider mites usually appear only on dry and desiccated plants, so spray the plant frequently and water more regularly.
Golden Dewdrop Common Diseases
Leaf Spot: Fungal leaf spot diseases can cause dark spots or patches on the leaves. Prune infected branches to improve air circulation around the plant. Fungicidal sprays may be necessary for severe infections. Copper sprays are generally considered safe and affordable and most are listed for organic gardening.
Powdery Mildew
This fungal disease forms a white, powdery coating on the leaves, stems, and flowers. Prune to Improve air circulation, avoid overhead watering, and apply fungicidal sprays as needed.
A solution of 8-12 tablespoons of household hydrogen peroxide (3%) in 1 gallon of water sprayed every three days for a week will reduce powdery mildew with diligent application.
Root Rot
Overwatering or poorly drained soil can lead to root rot, causing yellowing leaves, wilting, and eventual plant decline. Remedy: Ensure proper drainage and adjust watering practices. If unable to remediate the soil quality, you may need to move the plant to a location with better drainage.
Duranta Eerecta Propagation
Although it may take several tries and some time to propagate Duranta from cuttings, it’s well worth your effort.
Select a stem cutting: Choose a healthy, non-flowering stem measuring about 4 to 6 inches (10 to 15 cm) in length.
Prepare the cutting: Use clean, sharp pruning shears to make a clean cut just below a leaf node.
Remove lower leaves: Remove the lower leaves, leaving a few leaves at the top of the cutting.
Apply rooting hormone (optional): Dip the cut end of the cutting into a rooting hormone powder or gel to enhance root formation.
Plant the cutting: Insert the cut end of the stem into a well-draining potting mix or a mix of peat moss and perlite, ensuring at least one node is below the soil surface. I use a 50/50 mix of coco coir and perlite that provides both moisture retention and excellent drainage.
Provide optimal conditions: Place the potted cutting in a warm, bright location with indirect sunlight. Maintain a consistently moist but not waterlogged soil.
Rooting process: Keep the soil moist and provide high humidity by covering the cutting with a plastic bag or using a propagation tray with a clear lid. Roots should develop in a few weeks to a few months.
Transplanting: Once the roots have developed, carefully transplant the rooted cutting into a larger pot or desired planting location.

Tropical Hibiscus has to be the Hail Mary throw for any Florida gardener. These beautiful flowering shrubs are so easy to grow in our climate that cultivating a variety is a no-brainer. Tropical hibiscus care is simple and straightforward, and the amount of bloom you get for your buck (and effort) is simply incredible.
There seem to be an endless number of tropical hibiscus varieties, including some extravagantly flamboyant hybrids. Unfortunately, there are also a lot of scams floating around. If you seed tropical hibiscus for sale promising impossible-in-nature colors, it may be a complete scam.
If you live in the Southeastern U.S., specifically around the hot and humid Gulf Coast, you may have seen tropical hibiscus for sale and been tempted to purchase plants. Perhaps you thought they were fussy. They’re so pretty, they must be a pain to care for, right? Turns out, they’re not. They’re dead easy, and these showy exotics turn even the most mundane suburban spread into a tropical paradise.
Tropical Origins
Tropical hibiscus, or Hibiscus rosa-sinensis, is believed to have originated in China, particularly in the southern regions. It’s also native to India, Malaysia, Indonesia, Thailand, and the Philippines, along with the Pacific Islands, like Fiji, Samoa, Tonga, and Hawai’i.
Over the years, these beautiful plants have spread to other tropical climates in Africa, Australia, Central and South America, and the Caribbean. In these tropical regions, the hibiscus thrives in rainforests and coastal areas.
In Hawai’i, tropical hibiscus is part of native culture, making up the iconic lei garlands worn on special occasions. These blooms are worn in the hair, are used in floral displays, and signify beauty. Tropical hibiscus is also used medicinally and as offerings in spiritual ceremonies.
The tropical hibiscus embodies the spirit of “aloha’ – love, compassion, and hospitality.
How can you fail to fall in love with that?
I always like to joke that I don’t live in the Southern U.S., I live in the North Caribbean, so tropical hibiscus is one of the first ornamentals I added to our landscape.
Tropical hibiscus is a woody shrub that can reach a height of 6 to 10 feet tall, with a spread of 4 to 6 feet. The foliage is glossy and dark green, creating an attractive backdrop for its stunning flowers.

Dig the planting hole
Dig a hole that is slightly wider and deeper than the root ball of the hibiscus shrub. The hole should be large enough to accommodate the roots comfortably.
Remove the hibiscus from its container
Gently tap or squeeze the sides of the container to loosen the root ball. Carefully slide the hibiscus out of the container, taking care not to damage the roots.
Place the hibiscus in the hole
Position the hibiscus in the center of the hole, ensuring that it sits at the same depth as it was in the container. The top of the root ball should be level with the soil surface.
Add Amendments
For the best start, add an organic fertilizer in the planting hole that contains mycorrhizal fungi to improve nutrient uptake and root health. Compost is also another great soil amendment that adds richness to mediocre soils.
Backfill the hole
Fill the hole with the excavated soil, gently firming it around the roots as you go. Ensure there are no air pockets around the roots.
Water thoroughly
After planting, water the hibiscus thoroughly to settle the soil and hydrate the plant. Provide enough water to moisten the entire root ball as well as the soil around it.
Mulch around the plant
Apply a layer of organic mulch, such as wood chips, around the base of the hibiscus. This will help conserve moisture, suppress weeds, and regulate soil temperature.
First year care
Regularly water the hibiscus, keeping the soil evenly moist but not waterlogged. Water deeply whenever the top inch of soil feels dry.

Provide tropical hibiscus with a balanced fertilizer, such as a slow-release granular formula with an N-P-K ratio of 10-10-10 or 14-14-14. Feed every four to six weeks during the growing season, reducing or stopping fertilization during winter dormancy.
Horticulturists often recommend specific macronutrients and micronutrients for the optimal production of tropical hibiscus. Here are the essential nutrients that are typically recommended.
Macronutrients
Nitrogen (N) is essential for promoting leafy growth and overall plant vigor. It is particularly important during the active growth stages of tropical hibiscus.
Phosphorus (P) plays a crucial role in root development, flowering, and fruit production. It helps promote strong root systems and enhances flower and fruit formation.
Potassium (K) is vital for overall plant health, disease resistance, and flower quality. It aids in the regulation of water movement within the plant and supports the development of strong stems and roots.
Micronutrients
Iron (Fe) is necessary for chlorophyll synthesis and plays a key role in photosynthesis. It is important for maintaining healthy foliage and preventing yellowing of leaves (chlorosis).
Magnesium (Mg) is an essential component of chlorophyll and is critical for photosynthesis. It supports energy production and enzyme activation within the plant.
Zinc (Zn) is involved in various enzymatic processes and plays a role in hormone regulation, protein synthesis, and carbohydrate metabolism. It is essential for overall plant growth and development.
Manganese (Mn) is necessary for chlorophyll production and is involved in enzyme activation. It contributes to photosynthesis, nitrogen metabolism, and carbohydrate synthesis.
Copper (Cu) is required for various enzymatic reactions and is involved in plant respiration, photosynthesis, and lignin synthesis. It aids in overall plant growth and development.
It’s important to note that the specific nutrient requirements may vary depending on factors such as soil composition, growing conditions, and plant health. Conducting a soil test and consulting with your ag extension service can provide more precise nutrient recommendations tailored to your specific growing environment and goals.
Specialized Tropical Hibiscus Fertilizer
Fertilizers formulated specifically for tropical hibiscus, often labeled as “Hibiscus Fertilizer” or “Tropical Plant Fertilizer,” are available in the market and are formulated to meet the specific nutrient needs of these plants.
Fertilizing tropical hibiscus with acid-loving plant fertilizers can be beneficial if the soil pH is alkaline or if you are aiming to lower the pH slightly. Acid-loving fertilizers typically contain higher amounts of sulfur, which helps lower soil pH.
These fertilizers may also include additional nutrients that are beneficial for acid-loving plants, such as iron and manganese.
If you notice signs of nutrient deficiency or if your soil pH is consistently high, using an acid-loving plant fertilizer can help provide the necessary nutrients while also slightly adjusting the soil pH.
However, it’s important to note that tropical hibiscus can also thrive in slightly alkaline soils as long as the necessary nutrients are available.
Before applying any fertilizer, it’s recommended to conduct a soil test to determine the pH and nutrient levels of your soil.
Pruning Your Tropical Hibiscus
While tropical hibiscus is a low-care plant, it does require some pruning to make it look its best. You’ll want to prune in late winter or early spring before new growth emerges. You may also want to prune during the growing season to prevent it from becoming overgrown and leggy.
Pruning During the Growing Season.
You can prune your hibiscus back any time during the growing season as required to maintain its shape.

Size control
If necessary, trim back the overall size of the plant to maintain a desirable shape or control its height. Cut back the branches to the desired length, just above a set of healthy leaves.
Pruning cuts
Make clean, angled cuts above leaf nodes or buds, ensuring the remaining branches face outward to encourage outward growth.
Clean-up
Remove all the pruned branches and debris from the area around the plant. This helps prevent the spread of pests and diseases.
Aftercare
After pruning, provide regular care to support new growth. Water the plant appropriately, ensure it receives adequate sunlight, and follow up with a spring feeding once new growth emerges.
Tropical Hibiscus Propagation
There are a few different methods you can use for tropical hibiscus propagation: stem cuttings, air layering, or seed propagation. Stem cuttings are the most common and easiest method.
Prepare the Cuttings
Select a healthy and mature branch of the tropical hibiscus plant. Using clean and sharp pruning shears, cut a 4-6 inch section of the stem just below a leaf node (where leaves emerge). Remove any leaves from the lower half of the cutting.
Hormone Application (Optional)
To enhance root development during tropical hibiscus propagation, you can apply a rooting hormone to the base of the cutting according to the manufacturer’s instructions. This step is optional but can increase the success rate.
Planting the Cutting
Prepare a small pot with a well-draining potting mix. Make a hole in the soil using a pencil or your finger and insert the cutting about 1-2 inches deep into the soil. Firmly press the soil around the cutting to secure it.
Provide Ideal Conditions
Place the pot in a warm and bright location with indirect sunlight. Maintain a consistent temperature between 70-80°F (21-27°C). Keep the soil moist but not waterlogged. You can cover the pot with a plastic bag or place it in a propagation tray to create a humid environment.
Root Development
Over the next several weeks, the cutting will develop roots. Check the soil moisture regularly and mist the leaves if necessary to maintain humidity. Avoid direct sunlight, as it can scorch the cutting.
Transplanting
Once the cutting has developed a healthy root system, usually after 6-8 weeks, you can transplant it into a larger pot or into the garden if the conditions are suitable. Ensure the soil is well-draining and provide adequate watering and care as the plant establishes itself.
Note: Tropical hibiscus propagation from seed is also possible but requires more time and effort. It’s an approach for expert gardeners. It involves harvesting and germinating the seeds, followed by nurturing the seedlings until they are ready for transplanting.
Winter Care for Tropical Hibiscus
Protecting tropical hibiscus during the winter is crucial in regions where temperatures drop below their cold tolerance. Here are some steps to help safeguard your plants:

Pruning
Before the first frost, consider pruning your tropical hibiscus to a manageable size. Remove any dead or diseased branches and aim for a compact shape.
Mulching
Apply a layer of organic mulch around the base of the plant, such as straw or wood chips. This helps insulate the roots and retain moisture.
Covering
Use frost blankets, burlap, or old bedsheets to cover the entire plant during extremely cold nights. Secure the cover loosely to allow for airflow and prevent moisture buildup.
Remove the cover as soon as possible after sunrise. If temperatures are expected to drop for several nights in a row, you can leave the covers on.
Container plants
If your hibiscus is in a container, move it to a protected area like a garage or basement. Ensure the plant receives adequate light and water sparingly to prevent root rot.
Watering
During winter, reduce watering frequency to avoid waterlogged soil. Only water when the top inch of soil feels dry to the touch.
If the cold snap will be brief, water the day before the overnight temperatures drop. Water early enough to allow the day’s sunlight to heat the root zone. This will help keep the soil around the plant warmer overnight.
However, this technique is not suitable for longer cold spells. If you are expecting several nights of cold weather, don’t water until the weather warms enough to remove the coverings.
Temperature monitoring
Keep an eye on weather forecasts and be prepared to provide additional protection if unexpected cold snaps occur.
By implementing these measures, you can help protect your tropical hibiscus from winter damage and promote its health for the following growing season.
Tropical Hibiscus Pests and Diseases
Keep an eye out for common pests like aphids, spider mites, and whiteflies. Treat any infestations promptly using appropriate organic or chemical controls. Monitor for signs of diseases like leaf spot or powdery mildew and take necessary steps to address them.
Common Pests
Common pests affecting tropical hibiscus include aphids, whiteflies, spider mites, and mealybugs. Regularly inspect the plant for signs of infestation.
Here’s some guidance on identifying common insect pests that can infest tropical hibiscus:
Aphids
Look for clusters of small, soft-bodied insects on the undersides of leaves, flower buds, or stems.
Aphids can be green, black, brown, or other colors, depending on the species.
They often leave behind a sticky residue called honeydew, which can attract ants and promote the growth of sooty mold.
Whiteflies
Whiteflies are tiny, white or pale yellow insects that resemble small moths. They can be found on the undersides of leaves, typically in large numbers. When disturbed, whiteflies will fly up in a cloud of tiny insects.
Spider Mites
Spider mites are very small and may appear as tiny dots on the leaves. Look for fine webbing on the undersides of leaves, especially in cases of severe infestation. Spider mites can cause stippling or yellowing of the foliage.
Mealybugs
Mealybugs are soft-bodied insects covered in a white, cottony, waxy substance. They tend to congregate in protected areas, such as leaf axils, leaf undersides, and stem joints. Look for cottony masses and sticky residue on the plant surface.
Oleander caterpillars
Oleander caterpillars are vibrant and distinctive in appearance. They have a black body with bright orange or red stripes running along their length. The caterpillars have a slightly hairy or spiky texture.
When inspecting your hibiscus for pests, be sure to examine the undersides of leaves, as many pests prefer to hide in those areas. Additionally, closely monitor the overall health of your plant for signs of wilting, yellowing leaves, or stunted growth, as these can be indicators of a pest infestation.
Pest Remedy
Control pests by spraying the plant with an appropriate insecticide, focusing on the undersides of leaves where pests often congregate. Follow the product instructions and repeat applications as necessary.
Common Diseases
Tropical hibiscus can be susceptible to diseases such as leaf spot, root rot, and powdery mildew. Ensure proper watering practices, good air circulation, and avoid overhead watering to minimize disease incidence.
Leaf Spot
Leaf spot is a common fungal disease that affects tropical hibiscus. Look for circular or irregularly shaped spots on the leaves, usually with defined margins. The spots can vary in color, ranging from brown, black, or yellow to dark purple.
As the disease progresses, the spots may enlarge and merge, leading to the yellowing and defoliation of affected leaves.
Root Rot
Root rot is a fungal disease caused by overwatering, poor drainage, or soilborne pathogens. Observe the plant for signs of wilting or yellowing leaves that don’t respond to watering.
Gently remove the plant from the pot or dig around the root zone to inspect the roots. Healthy roots should appear white or off-white, while rotting roots may appear brown, mushy, or have a foul odor.
Severely affected plants may exhibit stunted growth and eventually die.
Powdery Mildew
Powdery mildew is a fungal disease characterized by a white or grayish powdery growth on the foliage. Look for a fine, talcum-like coating on the upper surfaces of leaves, stems, and even flowers.
Affected leaves may become distorted, curl, or drop prematurely. In severe cases, the powdery growth can cover a significant portion of the plant, inhibiting photosynthesis and weakening its overall health.
When identifying these diseases, careful observation of the plant’s symptoms and characteristics is essential. If you suspect any of these diseases, it is recommended to take appropriate measures for prevention, treatment, and control to minimize their impact on your tropical hibiscus.
Disease Remedy
To combat diseases, remove and dispose of affected plant material, improve air circulation, and apply appropriate fungicides as recommended by a local garden center or professional.

Do tropical hibiscus come back every year?
No, tropical hibiscus will not grow back after a cold winter in temperate climates. However, in frost-free regions or with proper protection, it may survive and continue to grow year-round.
What is the cause if my tropical hibiscus lost all leaves?
There can be several possible causes for a tropical hibiscus plant losing all its leaves. It could be due to environmental stressors such as cold temperatures, frost damage, or excessive exposure to direct sunlight. Overwatering or underwatering can also lead to leaf drop.
Can you grow tropical hibiscus from seed?
Yes, you can grow a tropical hibiscus from seed. However, it’s important to note that tropical hibiscus seeds can be a bit challenging to germinate and require specific conditions for successful growth.
What is the difference between tropical hibiscus vs hardy hibiscus?
Tropical hibiscus thrives in warm, tropical or subtropical climates and cannot tolerate freezing temperatures, while hardy hibiscus is adapted to colder regions and can withstand freezing temperatures.
Is tropical hibiscus tea safe to drink? Is tropical hibiscus what they use to make tea?

Do hibiscus grow better in pots or ground?
Hibiscus can thrive both in pots and in the ground, but each option has its considerations. When grown in pots, hibiscus plants offer the advantage of portability, allowing you to move them indoors during colder months or place them in optimal locations for sunlight. Potted hibiscus may require more frequent watering and fertilization due to limited soil volume.
How hot is too hot for hibiscus?
The optimal temperature range for hibiscus is typically between 60°F (15°C) and 90°F (32°C). When temperatures consistently exceed 90°F (32°C), hibiscus may experience reduced growth, wilting, leaf drop, and flower damage. High heat combined with intense sunlight can also lead to sunburn on the leaves.
How do you keep hibiscus blooming?
Ensure your tropical hibiscus receives consistent moisture. Feed your tropical hibiscus plant with a water-soluble bloom booster for acid-loving plants. Then work in some slow-release fertilizer formulated for flowering plants around the root zone and apply a layer of organic mulch to help retain moisture. Deadheading regularly will encourage the development of new buds.
