Florida’s tomato season has two distinct planting windows: spring and fall. Knowing exactly when to plant tomatoes in florida can mean the difference between a bumper crop and a total failure. The state’s unique climate—from humid subtropical in the north to tropical in the south—means timing is everything.
If you plant too early, cold snaps can kill your seedlings. Too late, and the summer heat will stop fruit from setting. This guide breaks down the exact dates for every region, so you can grow juicy, homegrown tomatoes without the guesswork.
When To Plant Tomatoes In Florida
Tomatoes are warm-season plants that need consistent temperatures above 50°F at night and 70-85°F during the day. Florida’s growing zones (8-11) create two main planting seasons: spring (February to April) and fall (August to September). The exact month depends on where you live.
Spring Planting Dates By Region
Spring is the most popular time for tomatoes, but you must avoid the last frost date. Here are the recommended windows:
- North Florida (Zone 8-9): Plant from mid-March to early April. Last frost usually occurs in late March.
- Central Florida (Zone 9-10): Plant from mid-February to mid-March. Soil warms up faster here.
- South Florida (Zone 10-11): Plant from January to February. You can even start in late December if it’s warm.
Fall Planting Dates By Region
Fall planting avoids the intense summer heat and gives you a second harvest. Plant early enough so tomatoes ripen before the first frost in northern areas.
- North Florida: Plant from late July to early August. Harvest before November frosts.
- Central Florida: Plant from mid-August to early September.
- South Florida: Plant from September to October. You can sometimes plant into November.
Why Timing Matters So Much
Tomatoes stop setting fruit when nighttime temperatures stay above 75°F or below 55°F. Florida’s summer heat (June-August) causes blossom drop, meaning flowers fall off without producing fruit. That’s why spring and fall are your only reliable windows.
Another reason: humidity. High humidity encourages fungal diseases like blight and powdery mildew. Planting in the right season gives your tomatoes a fighting chance before disease pressure peaks.
How To Determine Your Exact Planting Date
You can’t just rely on a calendar. Use these three methods to fine-tune your timing:
Check Your Last Frost Date
For spring planting, wait until 2-3 weeks after your area’s average last frost date. In North Florida, that’s usually late March. Central Florida’s last frost is mid-February. South Florida rarely sees frost.
You can find your exact frost date by searching “last frost date [your county] Florida” or using the NOAA climate data website.
Monitor Soil Temperature
Tomato seeds need soil at least 60°F to germinate. Transplants need soil above 55°F at night. Use a soil thermometer—insert it 4 inches deep in the morning. If it’s below 60°F, wait another week.
In South Florida, soil warms up by January. In North Florida, you might not hit 60°F until late March.
Watch The Weather Forecast
Don’t plant if a cold front is coming within 10 days. Even a light frost (32°F) can kill young plants. Cover them with row covers or frost cloth if a surprise cold snap hits, but it’s better to wait.
For fall planting, watch for hurricane season. Heavy rains can waterlog soil and damage roots. Plant after a dry spell if possible.
Best Tomato Varieties For Florida
Not all tomatoes thrive in Florida’s heat and humidity. Choose heat-tolerant, disease-resistant varieties. Here are the top performers:
Determinate (Bush) Varieties
These grow to a fixed size and ripen all at once. Great for canning or if you want a quick harvest.
- Celebrity: Resistant to fusarium wilt and nematodes. Produces medium-sized fruit in 70 days.
- Better Bush: Compact plant, good for containers. Ripens in 68 days.
- Roma: Classic paste tomato. Thrives in heat. Ready in 75 days.
Indeterminate (Vining) Varieties
These keep growing and producing until frost or heat stops them. You get a steady supply.
- Sweet 100: Cherry tomato that produces hundreds of fruits. Heat-tolerant.
- Cherokee Purple: Heirloom with rich flavor. Does well in Florida’s fall season.
- Arkansas Traveler: Bred for hot, humid climates. Produces pink fruit.
Hybrid Heat-Tolerant Options
These are specifically bred for Florida’s conditions.
- Heatmaster: Sets fruit even in high heat. Matures in 75 days.
- Solar Fire: Resistant to bacterial wilt. Good for spring planting.
- Florida 91: Developed by University of Florida. Tolerates heat and humidity.
Step-By-Step Planting Guide
Once you’ve chosen your date and variety, follow these steps for success.
Prepare The Soil
- Choose a spot with full sun (at least 8 hours daily).
- Test soil pH—tomatoes prefer 6.0-6.8. Florida soil is often acidic, so add lime if needed.
- Mix in 2-3 inches of compost or well-rotted manure. This improves drainage and nutrients.
- Add a slow-release fertilizer with calcium to prevent blossom end rot.
Plant Transplants Properly
- Dig a hole deeper than the root ball—tomatoes can root along the stem.
- Remove lower leaves, leaving only the top 2-3 sets.
- Place the plant in the hole so the top leaves are just above soil level.
- Backfill with soil, press gently, and water thoroughly.
- Space plants 2-3 feet apart for good air circulation.
Water And Mulch
Water deeply once a day for the first week, then every 2-3 days. Florida’s sandy soil drains fast, so check moisture by sticking your finger 2 inches deep. If dry, water.
Apply 2-3 inches of organic mulch (straw, pine straw, or shredded leaves) around the base. This keeps soil cool, retains moisture, and prevents weeds.
Support Your Plants
Use cages, stakes, or trellises. Indeterminate varieties need tall supports (5-6 feet). Determinate varieties do fine with 3-4 foot cages. Install supports at planting time to avoid root damage later.
Common Florida Tomato Problems
Even with perfect timing, issues can arise. Here’s how to handle them.
Blossom End Rot
Dark, sunken spots on the bottom of fruit. Caused by calcium deficiency and inconsistent watering. Solution: Keep soil evenly moist, add calcium-rich fertilizer, and mulch.
Fungal Diseases
Early blight, late blight, and powdery mildew thrive in Florida’s humidity. Prevent by watering at soil level (not on leaves), spacing plants for airflow, and using copper fungicide at first sign.
Pests
Hornworms, aphids, and whiteflies are common. Handpick hornworms (they’re big). Spray aphids with neem oil or insecticidal soap. Use yellow sticky traps for whiteflies.
Heat Stress
If temperatures exceed 90°F for several days, flowers may drop. Shade cloth (30% shade) can help. Water in the morning to cool roots.
Fertilizing Schedule For Florida Tomatoes
Tomatoes are heavy feeders. Use a balanced fertilizer (10-10-10) at planting. Then switch to a low-nitrogen, high-phosphorus formula (5-10-10) once flowers appear.
- At planting: Mix 1 tablespoon of 10-10-10 per plant into the soil.
- After 3 weeks: Side-dress with 1 tablespoon of 5-10-10 per plant.
- Every 2 weeks: Apply liquid fertilizer like fish emulsion or seaweed extract.
Stop fertilizing once fruit starts ripening to avoid splitting.
Harvesting And Storing
Tomatoes are ready when they’re fully colored and slightly soft to the touch. Pick them in the morning for best flavor. Store at room temperature—never refrigerate, as cold ruins texture.
If a frost is coming, pick all green tomatoes and let them ripen indoors in a paper bag with an apple or banana. They’ll turn red in 1-2 weeks.
Frequently Asked Questions
Can I Plant Tomatoes In Florida In Summer?
It’s not recommended. Summer heat (June-August) causes blossom drop and disease. Stick to spring and fall planting windows.
What Is The Best Month To Plant Tomatoes In Florida?
For spring, March is best for most of Florida. For fall, August or September works well. Adjust by region.
How Late Can I Plant Tomatoes In Florida?
In South Florida, you can plant as late as October. In North Florida, don’t plant after early August for fall, or after early April for spring.
Do Tomatoes Need Full Sun In Florida?
Yes, at least 8 hours of direct sun daily. In extreme heat, afternoon shade from a taller plant or shade cloth can help.
Should I Start Tomatoes From Seed Or Transplants?
Transplants are easier for beginners and give you a head start. Seeds work if you have a warm, protected spot to germinate them 6-8 weeks before planting.
Growing tomatoes in Florida is totally doable once you nail the timing. Remember: spring for North and Central, fall for South, and always check your local frost dates. With the right variety and a little care, you’ll be picking ripe, sweet tomatoes straight from the vine.
