Question 1

Can you grow lettuce in Florida summers?

Accepted Answer

No, Florida summers are too hot for lettuce which bolts and goes to seed quickly in heat. The growing window for lettuce in Florida is September through April when cooler temperatures prevail.

Question 2

What lettuce varieties grow best in Florida winters?

Accepted Answer

Jericho Romaine, Manoa butterhead, Little Gem, and loose-leaf varieties like Black-Seeded Simpson, Red Sails, and Salad Bowl perform best. Avoid crisphead varieties like iceberg which need more consistent cool temperatures.

Question 3

Why won't iceberg lettuce grow in Florida?

Accepted Answer

Iceberg and other crisphead lettuces need consistent cool temperatures below 70°F. Florida winters fluctuate between freezing nights and 80°F days, causing crispheads to bolt or fail to form proper heads.

Question 4

When should I plant lettuce seeds in Florida?

Accepted Answer

Plant lettuce seeds from September through April, avoiding late December through January when frost risk is highest. Start seeds indoors in August when outdoor temperatures exceed 80°F for fall transplanting.

Question 5

Do lettuce seeds germinate in Florida heat?

Accepted Answer

No, heat-tolerant lettuce varieties struggle to germinate above 80°F. Start seeds indoors with temperature control during hot months, then transplant seedlings when outdoor conditions improve in fall.

Question 6

How long does lettuce take to grow in Florida?

Accepted Answer

Loose-leaf lettuce can be harvested 40-50 days after planting, with cut-and-come-again harvests starting earlier. Heading varieties like romaine need 60-75 days to form full heads before harvest.

Question 7

Can you grow lettuce in containers in Florida?

Accepted Answer

Yes, shallow containers (4-6 inches deep) work excellently for loose-leaf lettuce in Florida. Container growing allows temperature control, succession planting, and requires less soil amendment than in-ground growing.

Question 8

Does lettuce need full sun in Florida winters?

Accepted Answer

Yes, during the winter, lettuce needs 6 hours of sunlight daily. Position containers or garden beds for maximum winter light exposure since the sun is lower and days are shorter during growing season.

Question 9

How do you protect lettuce from Florida freezes?

Accepted Answer

Cover lettuce with row covers, old sheets, or beach towels during freeze warnings. Lettuce handles light frosts but prolonged freezing below 32°F damages plants, though Florida freezes are rare.

Question 10

What's the best fertilizer for Florida lettuce?

Accepted Answer

Use slow-release organic fertilizer at planting (lasts 3-4 months), supplement with compost or composted manure mid-season, and apply fish emulsion for quick nutrient boosts during active growth.

Question 11

Can you harvest lettuce multiple times in Florida?

Accepted Answer

Yes, loose-leaf varieties work as cut-and-come-again crops. Harvest individual outer leaves near the ground while allowing smaller inner leaves to continue growing for continuous harvests throughout winter.

Question 12

How often should you water lettuce in Florida winters?

Accepted Answer

Water lettuce regularly since Florida winters are dry and windy. Shallow-rooted lettuce needs consistent moisture near the surface, requiring more attention than deep-rooted vegetables during the drier season.

Question 13

Why grow lettuce in containers instead of garden beds?

Accepted Answer

Containers offer temperature control (easy to move), succession planting flexibility, reduced soil amendment costs, and more garden space for slower-growing crops like broccoli and cabbage during limited growing seasons.

Question 14

What spacing does lettuce need in Florida gardens?

Accepted Answer

Space heading lettuce 8-10 inches apart in garden beds for proper head development. Loose-leaf varieties can be planted closer or scattered in shallow containers for cut-and-come-again harvesting.

Question 15

Can Jericho Romaine grow through June in Florida?

Accepted Answer

Yes, Jericho Romaine is exceptionally heat-tolerant for a lettuce variety. Developed in Israel for hot climates, it can continue growing into June in Florida when other lettuces have long since bolted when provided with midday shade.
