Figuring out when to plant tomatoes in florida is the single most important step for a successful harvest. The answer isn’t a single date, but a window that shifts depending on where you live in the Sunshine State. Florida’s tomato planting calendar revolves around avoiding the extreme heat of summer and the rare frost of winter.
Most gardeners get this wrong by planting too late in spring. The heat arrives fast, and tomato blossoms simply drop off the vine when nighttime temps stay above 75°F. You end up with a leafy plant and zero fruit.
Let’s break down the exact timing for every region, plus the varieties that actually perform well here.
When To Plant Tomatoes In Florida
The state splits into three main climate zones for planting purposes. North Florida, Central Florida, and South Florida each have their own unique windows. You cannot use a one-size-fits-all date.
Your goal is to have fruit set before the heat stress period begins. For most of the state, that means planting in late winter or very early spring. A second, smaller window exists in late summer for a fall crop.
North Florida Planting Windows
North Florida includes Jacksonville, Tallahassee, and Gainesville. This region gets actual frost and freezing temperatures in December and January. The growing season is shorter than the rest of the state.
For the spring crop, you should plant between March 1 and March 15. The last frost date is typically around mid-March. If you plant too early, a late cold snap will kill your transplants.
For the fall crop, plant between July 15 and August 15. This timing allows the plants to mature before the first frost arrives in late November. The heat of August is brutal, but the plants will establish roots and explode with growth once September cools down.
Best Varieties For North Florida
- Early Girl (matures in 50 days)
- Celebrity (disease resistant)
- Better Boy (heavy producer)
- Rutgers (classic flavor)
Central Florida Planting Windows
Central Florida covers Orlando, Tampa, and Daytona Beach. Frost is rare but possible in January. The heat arrives earlier and stays longer than in the north.
For the spring crop, plant between February 1 and February 15. This gives you a head start before the heat of May shuts down production. Some gardeners push it to March 1, but you risk losing the early yield.
For the fall crop, plant between August 15 and September 15. This is the more productive window for Central Florida. The milder fall weather allows for a longer harvest period, often lasting into December.
Best Varieties For Central Florida
- Florida 91 (heat tolerant)
- Solar Fire (sets fruit in heat)
- Heatmaster (bred for Florida)
- Sweet 100 Cherry (indeterminate)
South Florida Planting Windows
South Florida includes Miami, Fort Lauderdale, and Naples. This region rarely sees frost. The challenge here is extreme heat and humidity for most of the year. You have the longest growing season, but the summer months are completely off-limits.
For the spring crop, plant between January 1 and February 1. This is the absolute earliest window in the state. The mild winter weather is perfect for tomato growth.
For the fall crop, plant between September 1 and October 1. This is actually the preferred window for South Florida. The plants will thrive through the mild winter and produce into spring.
You can also plant a winter crop in November in South Florida, but you need to use cold-tolerant varieties. The risk of a stray cold front is low, but it exists.
Best Varieties For South Florida
- Everglades Tomato (native, very heat tolerant)
- Sweet Million (cherry type)
- Phoenix (heat setter)
- BHN 968 (disease resistant)
Understanding The Heat Factor
Tomatoes are temperature-sensitive plants. They do not set fruit when nighttime temperatures stay above 75°F. The pollen becomes sterile and the flowers drop off. This is called “blossom drop.”
Daytime temps above 90°F also cause problems. The plant focuses on survival, not reproduction. You will see lush green growth but no tomatoes.
This is why the planting date matters so much. You need the plants to be flowering and setting fruit before the heat arrives. A tomato plant takes about 60 to 80 days to reach maturity from transplant. Count backward from your expected heat date to find your planting window.
Why Fall Planting Is Often Better
Many Florida gardeners swear by the fall crop over the spring crop. The reason is simple. Fall temperatures are declining, not rising. The plants experience less stress during fruit set.
Pests are also less active in the fall. The whitefly and leafminer populations drop as the weather cools. Your plants will be healthier and require less intervention.
The only downside is the intense heat during the first few weeks after planting. You need to water deeply and provide shade cloth for the first month. Once October arrives, the plants take off.
Soil Temperature Requirements
Air temperature is not the only factor. Soil temperature matters just as much. Tomato seeds will not germinate in soil below 60°F. Transplants will struggle if the soil is cold.
You can check soil temperature with a simple probe thermometer. Insert it four inches into the ground. Wait for a reading above 65°F before planting. This is non-negotiable for a healthy start.
If the soil is too cold, the roots will not grow. The plant will sit there, turning yellow and eventually dying. You waste weeks of valuable time.
How To Warm The Soil
- Lay black plastic mulch over the planting bed two weeks before planting.
- This absorbs solar heat and raises the soil temperature by 5 to 10 degrees.
- Cut holes in the plastic when you are ready to transplant.
- This also suppresses weeds and keeps the fruit off the ground.
Starting From Seed Vs. Transplants
You have two options for getting tomatoes into the ground. Starting from seed indoors gives you more variety choices. Buying transplants from a nursery is faster and easier.
If you start from seed, you need to count backward from your planting date. Tomato seeds take about 6 to 8 weeks to reach transplant size. Start them indoors under grow lights.
For a March 1 planting in North Florida, start seeds on January 15. For a February 1 planting in Central Florida, start seeds on December 15. For a January 1 planting in South Florida, start seeds on November 15.
Nursery transplants are already 6 to 8 weeks old. You can plant them immediately on your target date. The downside is limited variety selection. Most big box stores only carry a few common types.
Hardening Off Transplants
You cannot take a plant from indoors and stick it straight into the ground. The sudden change in light and temperature will shock it. The leaves will turn white and the plant may die.
Hardening off is a gradual process. It takes about 7 to 10 days. You expose the plants to outdoor conditions for increasing amounts of time each day.
- Day 1-2: Place plants outside in a shaded spot for 1 hour.
- Day 3-4: Increase to 3 hours in partial sun.
- Day 5-6: Increase to 6 hours in full sun.
- Day 7-8: Leave them out overnight if no frost is forecast.
- Day 9-10: Plant them in the ground.
This process is critical. Skipping it will set your plants back by weeks. You might lose the entire season if the heat arrives before they recover.
Regional Microclimates Matter
The general zones are a good starting point, but your specific yard may differ. Urban areas are warmer than rural areas. Concrete and pavement absorb heat and release it at night.
If you live near the coast, the ocean moderates temperatures. Your nights will be warmer in winter and cooler in summer. This can extend your growing season by a few weeks.
If you live inland, you get more extreme temperature swings. Frost is more likely in winter. The heat is more intense in summer. Adjust your planting dates accordingly.
Check Your Local Extension Office
The University of Florida has an extension office in every county. They publish local planting calendars that are specific to your area. These are the most reliable sources of information.
You can find them online or call them directly. They also offer soil testing services. This is a free or low-cost way to know exactly what your soil needs.
Your neighbors are also a great resource. If they have been gardening in your area for years, they know the local quirks. Ask them what works and what does not.
Common Mistakes To Avoid
Even with perfect timing, you can ruin your crop with simple errors. Here are the most common mistakes Florida gardeners make.
- Planting too deep in hot soil (the stem rots).
- Overwatering (causes root rot and splits).
- Underwatering (causes blossom end rot).
- Using too much nitrogen fertilizer (lots of leaves, no fruit).
- Ignoring pest pressure (whiteflies and hornworms).
- Not staking or caging (fruit rots on the ground).
Tomatoes need consistent moisture. Water deeply two to three times per week, not a little bit every day. The soil should be moist but not soggy.
Use a balanced fertilizer with a ratio like 10-10-10. Apply it at planting time and then again when the first fruits appear. Do not overdo it.
Frequently Asked Questions
Can I Plant Tomatoes In Florida In May?
Technically yes, but you will not get much fruit. The heat in May is already too intense for fruit set. You are better off waiting for the fall planting window.
What Is The Best Month To Plant Tomatoes In Florida?
It depends on your region. For North Florida, March is best. For Central Florida, February is best. For South Florida, January or September are both excellent.
Do tomatoes grow year-round in Florida?
In South Florida, you can grow them almost year-round if you choose the right varieties. In North and Central Florida, you get two distinct seasons: spring and fall. The summer is too hot.
How long does it take to grow tomatoes in Florida?
Most varieties take 60 to 80 days from transplant to first harvest. Cherry tomatoes are faster, around 50 to 60 days. Larger beefsteak types take longer, up to 90 days.
Should I plant determinate or indeterminate tomatoes in Florida?
Determinate varieties are bush-type and produce all at once. They are good for canning. Indeterminate varieties are vining and produce over a longer period. They are better for fresh eating. In Florida, indeterminate varieties often perform better because they spread out the harvest.
Final Planting Checklist
Here is a simple checklist to follow before you put any tomato plant in the ground.
- Confirm your region’s planting window.
- Check the 10-day weather forecast for frost or extreme heat.
- Test your soil temperature (should be above 65°F).
- Harden off your transplants for 7 to 10 days.
- Amend the soil with compost and a balanced fertilizer.
- Plant deep, burying the bottom two-thirds of the stem.
- Water thoroughly immediately after planting.
- Mulch around the base to retain moisture.
- Install stakes or cages right away.
- Monitor for pests weekly.
Tomato growing in Florida is not hard once you understand the timing. The key is to work with the climate, not against it. Plant early enough to beat the heat, and you will be rewarded with a bumper crop.
If you miss the spring window, do not panic. The fall crop is often better anyway. Mark your calendar for the fall dates and try again. Every season is a learning experience.
One last tip. Keep a garden journal. Write down when you planted and what the weather did. After a year or two, you will have your own personal data that is even more accurate than any general guide. That is the secret to becoming a successful Florida tomato grower.
