Growing Cabbage from Seed

Growing cabbage from seed in your own garden is a great way to save money and stock up on one of homesteaders’ favorite storage crops.

Cabbage is a nutritious cool-season vegetable prized for its dense, leafy heads and exceptional storage qualities. Home gardeners grow cabbage for its impressive yields and versatility in the kitchen. The vegetable works well in coleslaw, sauerkraut, stir-fries, soups, and roasted dishes.

Cabbage offers substantial amounts of vitamin C, vitamin K, fiber, and antioxidants. In the garden, cabbage serves as a productive cool-season crop that stores well for months after harvest.

This member of the brassica family, Brassicaceae, is scientifically known as Brassica oleracea var. capitata. Native to the Mediterranean and Western Europe, cabbage has been cultivated for thousands of years.

The crop thrives in USDA hardiness zones 1 through 10 when planted during appropriate seasons. It performs best during cool spring and fall weather.

Popular varieties include Early Jersey Wakefield, Copenhagen Market, Danish Ballhead, Red Acre, Savoy King, and Golden Acre.

Cabbage grows as an annual, completing its lifecycle in one growing season. The plant performs best when daytime temperatures range between 60 and 70 degrees Fahrenheit. Cabbage requires full sun, consistent moisture, and fertile soil rich in organic matter.

The crop tolerates frosts and develops sweeter flavor when exposed to light freezes. Hot weather above 80 degrees Fahrenheit causes poor head formation, splitting, and bolting.

What to Know About Growing Cabbage

Cabbage grows 12 to 18 inches tall and spreads 18 to 24 inches wide at maturity. The plant develops a compact, rounded growth habit with a short central stem. Large, thick leaves with prominent veining form a tight head in the center.

The outer leaves are blue-green or purple-red depending on variety, with a waxy coating. Foliage wraps around itself in overlapping layers to create the dense head.

The edible portion is the entire head composed of tightly packed leaves. The head forms at the center of the plant on a short stem. Heads can be round, flat, or pointed depending on variety. The outer wrapper leaves protect the inner head.

Both the dense inner head and outer leaves are edible, though outer leaves are typically tougher. The head appears as a compact ball of overlapping leaves sitting low to the ground.

Key Requirements for Growing Cabbage

Cabbage requires specific conditions to produce solid, well-formed heads. Understanding the plant’s basic requirements helps ensure successful cultivation and good harvests.

• Lifespan: Annual
• Growing season: Cool season, spring and fall
• Mature height: 12-18 inches
• Mature spread: 18-24 inches
• Light: Full sun, 6-8 hours daily
• Water: 1-1.5 inches per week
• Soil: Rich, well-draining, pH 6.0-7.5
• Feeding: Heavy feeder, needs regular nitrogen

Timing Your Cabbage Planting for Success

Cabbage seeds can be started indoors for transplanting or sown directly into the garden. Timing varies across climate zones based on frost dates and temperature patterns. Proper timing ensures plants mature during cool weather for best head development.

Zones 3-5

Start cabbage seeds indoors 6 to 8 weeks before the last expected spring frost for spring crops. Direct sow seeds outdoors 2 to 4 weeks before the last frost date.

For fall crops, start seeds indoors in mid June or direct sow in early to mid July, timing harvest for 2 to 3 weeks before the first fall frost.

Zones 6-8

Start cabbage seeds indoors in late January through February for spring crops. Direct sow seeds outdoors in late February through March.

For fall crops, start seeds indoors in late June through July or direct sow in late July through early August. In zone 8, gardeners can also plant in late summer for winter harvest.

Zones 9-12

Start cabbage seeds indoors in late summer for fall planting. Direct sow seeds outdoors from September through February, treating cabbage as a fall, winter, and early spring crop. In these warm zones, avoid planting during hot summer months. Focus plantings from October through January for best results.

Preparing the Garden Bed for Growing Cabbage

Proper site selection and soil preparation are essential for growing cabbage successfully. The plant requires specific conditions to develop solid, well-formed heads.

Choosing a Location

Select a garden bed with full sun exposure and good air circulation. Choose an area where brassicas have not grown in the past 2 to 3 years to reduce disease and pest pressure.

Avoid low-lying spots where cold air settles or water pools. Good drainage is essential for healthy root development and prevents root diseases.

Light Requirements

Cabbage requires full sun for optimal growth and head development. Provide at least 6 to 8 hours of direct sunlight daily. Insufficient light results in loose heads and slow growth. In very hot climates, light afternoon shade may help during warm spells.

Moisture

Cabbage needs consistently moist soil throughout the growing season. Choose a location where you can water regularly and deeply. The site should drain well enough to prevent waterlogging while retaining adequate moisture. Uneven watering causes head splitting and poor quality.

Space Requirements

Allow adequate space for cabbage plants to reach full size. Plan for 18 to 24 inches between plants in all directions. Proper spacing ensures good air circulation and reduces disease problems. Crowded plants compete for nutrients and produce smaller heads.

Soil Type

Cabbage thrives in rich, well-draining soil with high organic matter content. Work 3 to 4 inches of compost or aged manure into the top 8 to 10 inches of soil before planting.

The ideal soil pH ranges from 6.0 to 7.5. Test soil and adjust pH if needed. Cabbage is a heavy feeder and benefits from nutrient-rich soil.

Direct Sowing Cabbage Seeds in the Garden

Cabbage can be direct sown in the garden once soil warms and conditions are right. Direct sowing works well for fall crops and in zones with long cool seasons.

• Depth: Plant seeds half an inch deep in rows spaced 24 to 30 inches apart
• Spacing: Sow seeds 2 to 3 inches apart, thin to 18 to 24 inches once seedlings develop 2 to 3 true leaves
• Moisture: Water immediately after planting and keep soil consistently moist until seedlings emerge
• Temperature: Soil temperature 60 to 75 degrees Fahrenheit, optimal at 70 degrees Fahrenheit
• Light: Seeds do not need light to germinate
• Germination time: 5 to 10 days

Starting Cabbage Seeds Indoors for Transplanting

Cabbage starts successfully indoors and benefits from the controlled environment. Indoor starting provides stronger transplants and earlier harvests.

• Seed starting mix: Use lightweight commercial seed starting mix or combine equal parts peat moss or coco coir, vermiculite, and perlite
• Containers: Choose containers with drainage holes, cell trays with 2 to 3 inch cells or soil blocks work well
• Depth: Plant seeds half an inch deep, one or two seeds per cell
• Moisture: Water gently after planting, keep mix consistently moist but not waterlogged, bottom watering prevents disturbing seeds
• Temperature: Maintain 60 to 75 degrees Fahrenheit for germination, use heat mat if needed
• Light: Seeds do not require light to germinate, move seedlings to bright light immediately after emergence, provide 14 to 16 hours daily
• Germination time: 5 to 10 days
• Thinning: Thin to one seedling per cell once first true leaves develop

When to Plant Out Cabbage for Best Results

Cabbage seedlings are ready to transplant when they have 4 to 6 true leaves and stand 4 to 6 inches tall. This typically occurs 4 to 6 weeks after germination. Transplant in early spring 2 to 4 weeks before the last frost date or in mid to late summer for fall crops. Choose a cloudy day or transplant in the evening to reduce stress.

Hardening Off Cabbage Plants

Begin hardening off cabbage seedlings 7 to 10 days before transplanting to prepare them for outdoor conditions.

• Day 1-2: Place seedlings outdoors in a sheltered, shaded location for 1 to 2 hours
• Day 3-4: Gradually increase outdoor exposure by 1 to 2 hours each day, move into partial sun
• Day 5-7: Continue increasing time outdoors daily until plants remain outside all day and night
• Temperature: Keep plants indoors if temperatures drop below 35 degrees Fahrenheit
• Watering: Reduce watering slightly during hardening off but do not let plants wilt
• Protection: Bring seedlings indoors if harsh weather threatens, resume hardening once conditions improve

Planting Out Cabbage in the Garden

Dig holes slightly deeper than the root ball of each seedling and prepare the planting area.

• Depth: Place seedlings so the base of the stem sits at the same depth it grew in the container
• Spacing: Space holes 18 to 24 inches apart in rows set 24 to 30 inches apart
• Planting: Remove seedlings carefully from containers, gently loosen circling roots, fill around roots with soil and firm gently
• Mulching: Apply 2 to 3 inch layer of organic mulch around plants, keep mulch pulled back 2 to 3 inches from stems
• Timing Your Cabbage Planting for SuccessWater thoroughly immediately after planting to moisten soil 6 to 8 inches deep, water daily for the first week if rainfall is insufficient, then water deeply when top inch of soil feels dry

Caring for Growing Cabbage Plants

Regular maintenance ensures healthy plants and solid head development. Cabbage requires consistent care throughout the growing season.

Watering

Water cabbage consistently to maintain evenly moist soil. Provide 1 to 1.5 inches of water per week through rainfall or irrigation. Water deeply to encourage strong root development.

Check soil moisture by inserting your finger 2 inches into the soil. Water when the top inch feels dry. Inconsistent watering causes head splitting, cracking, or bitter flavor. Water at the base of plants rather than overhead to reduce disease risk.

Feeding

Feed cabbage regularly as a heavy feeder requiring substantial nutrients. Side-dress plants with compost or balanced fertilizer 3 weeks after transplanting. Apply nitrogen-rich fertilizer again when plants are 12 inches tall and once more when heads begin to form.

Use fish emulsion, blood meal, or complete vegetable fertilizer according to package directions. Yellowing leaves indicate nitrogen deficiency.

• Feed every 3 to 4 weeks during active growth
• Use nitrogen-rich fertilizer for leafy growth
• Switch to balanced fertilizer when heads form
• Avoid over-fertilizing which causes loose heads

Weeding

Keep the area around cabbage plants free of weeds. Weeds compete for nutrients, water, and light. Hand-pull weeds carefully to avoid disturbing shallow roots. Mulch suppresses weed growth significantly.

Remove weeds when small before they become established. Cultivate shallowly around plants to avoid root damage.

Pest Control

Monitor cabbage regularly for common brassica pests. Cover plants with floating row covers immediately after transplanting to exclude cabbage moths, flea beetles, and other flying pests.

Check undersides of leaves weekly for imported cabbageworm eggs and larvae. Hand-pick caterpillars or spray with Bt (Bacillus thuringiensis). Watch for aphids on new growth and remove with water spray.

• Use row covers to prevent cabbage moths from laying eggs
• Hand-pick cabbage worms and cabbage loopers
• Spray Bt for caterpillar control
• Remove aphids with water or insecticidal soap
• Check for cabbage root maggots at soil level
• Rotate crops yearly to reduce soil-borne pests

Tips and Tricks for Growing Cabbage Successfully

Cabbage responds well to specific practices that encourage solid heads and prevent common problems. Understanding these techniques helps maximize yields and head quality.

Harvest cabbage heads when they feel firm and solid when squeezed gently. Cut the head at the base with a sharp knife, leaving the outer wrapper leaves and stem in the ground. In some varieties, small secondary heads may form from buds on the remaining stem, providing a bonus harvest.

Water cabbage consistently throughout the growing season to prevent stress. Uneven moisture causes head splitting, especially as heads near maturity. Maintain steady soil moisture with deep watering and mulch. Reduce watering slightly as heads approach full size to minimize splitting risk.

Plant cabbage at the right time for your zone. The crop needs 60 to 110 days of cool weather to mature properly depending on variety. Temperatures above 80 degrees Fahrenheit cause poor head formation, loose heads, and bolting. Time plantings so heads develop when temperatures stay between 60 and 70 degrees Fahrenheit.

Choose appropriate varieties for your planting season. Early varieties mature quickly for spring harvests. Storage varieties take longer but keep for months in cool storage. Select cold-hardy varieties for fall planting in northern zones.

Check soil pH before planting cabbage. The crop prefers slightly acidic to neutral soil with pH 6.0 to 7.5. Add lime several weeks before planting if pH falls below 6.0. Low pH increases risk of clubroot disease which destroys roots.

Harvesting Cabbage from Your Garden

Cabbage reaches harvest maturity when heads are firm, solid, and fully formed. Proper timing and handling preserve quality and maximize storage life.

When to Harvest Cabbage

Harvest cabbage when heads feel firm and solid when squeezed gently. Most varieties are ready when heads reach 4 to 10 inches in diameter depending on the type.

Early varieties mature 60 to 70 days after transplanting while storage varieties take 80 to 110 days.

Check heads regularly once they begin forming as timing varies by variety and weather. Harvest in the morning after dew dries for best quality. Cut heads at the base with a sharp knife, leaving a few wrapper leaves attached for protection.

Harvest before heads split or bolt in hot weather. Light frosts improve flavor and sweetness in fall-grown cabbage.

How to Clean and Prepare Cabbage

Remove any damaged or loose outer leaves from harvested heads. Rinse the head under cool running water to remove soil and debris. Cut the head in half or quarters and remove the tough core.

Slice or shred cabbage as needed for recipes. Fresh cabbage requires minimal preparation beyond washing and cutting.

How to Store Fresh Cabbage

Store fresh cabbage in the refrigerator wrapped loosely in plastic or placed in a perforated plastic bag. Refrigerate for 2 to 3 weeks for best quality.

For longer storage, keep heads in a cool, humid location such as a root cellar at 32 to 40 degrees Fahrenheit with 90 to 95 percent humidity.

Storage varieties keep for 3 to 5 months under proper conditions. Remove any damaged outer leaves periodically during storage.

Cooking with Cabbage in Your Kitchen

• Pickling: Pack shredded or chopped cabbage in jars with vinegar brine and spices for refrigerator pickles or process in a water bath canner for shelf-stable pickles
• Dehydrating: Shred cabbage thinly and dehydrate at 125 degrees Fahrenheit until crisp, then store in airtight containers for soups and stews
• Root cellar storage: Store whole heads unwrapped in a cool, humid location at 32 to 40 degrees Fahrenheit for 3 to 5 months
• Pressure canning: Process cabbage following USDA guidelines

Collecting Cabbage Seeds for Replanting

Cabbage produces seeds in its second year of growth. The plant must overwinter and bolt to flower the following season. Select the healthiest plants with the best head quality for seed saving. Leave heads on plants past harvest maturity.

The head will eventually split and send up a tall flowering stalk. Yellow flowers appear on branching stems and attract pollinators. Cabbage cross-pollinates readily with other brassicas including broccoli, cauliflower, and kale. Isolate seed plants by at least half a mile from other flowering brassicas.

Allow flowers to mature and form long, narrow seed pods. The pods turn from green to tan or brown as they ripen. Seeds are ready when pods are completely dry and brittle, typically 4 to 6 weeks after flowering ends. Cut seed stalks and place in a paper bag. Hang in a warm, dry location for 2 to 3 weeks.

Shake the bag to release seeds from dried pods. Separate seeds from chaff. Cabbage seeds are small, round, and dark brown to black when mature. Store cleaned seeds in paper envelopes or glass jars. Label with variety name and collection date. Cabbage seeds remain viable for 4 to 5 years when stored in a cool, dry, dark location.
