If you’ve been wondering what to plant in Florida in August, I have great news for you: it’s prime time to get your fall tomato garden started! I know August sounds like a wild time to plant anything here in Florida, with all that heat and humidity, but tomatoes actually love this season when you set them up right. The timing works out beautifully because your plants will be maturing right as our temperatures cool down in October and November. What to Plant in Florida in August: Starting Your Fall Tomato Garden is a popular choice for gardeners.
I’ve been growing fall tomatoes in my Central Florida yard for years, and honestly, the fall harvest is my favorite of the whole year. The fruit just tastes better when it ripens in cooler weather. So let’s dig in and talk about how to make this work for you!
Why August Is the Sweet Spot for Starting Your Fall Tomato Garden in Florida
August might feel counterintuitive for planting, but the timing is actually really smart for us Florida gardeners. Tomatoes need about 70 to 80 days to mature from transplant, which means plants you put in the ground in August will be producing fruit right around October and November. That’s when our temperatures finally drop into that perfect 65 to 85 degree range that tomatoes absolutely love for setting fruit.
The key thing to understand is that tomatoes won’t set fruit when nighttime temps stay above 75 degrees. If you wait too long to plant, you’ll miss that sweet fall window entirely. I made that mistake my first year and ended up with a bunch of leafy plants and zero tomatoes. Don’t be like early-me!
You’ll want to get transplants in the ground by mid-August at the latest if you’re in South Florida, and you can stretch it to early September if you’re in North Florida. The University of Florida IFAS Extension has a great guide on tomato timing by region that I always reference when planning my garden.
Starting from seed indoors in late July gives you even more control over your plants. I started doing this a few years ago and the results have been noticeably better than buying transplants from the garden center.

Not every tomato variety does well in Florida’s heat and humidity, so picking the right one makes a huge difference. I’ve tried a lot of varieties over the years, and some of my favorites for fall planting are Celebrity, Solar Fire, Heatmaster, and Sweet 100 cherry tomatoes. These varieties were basically bred for conditions like ours, so they handle the heat and are more resistant to the diseases that love our humid climate.
Heatmaster is one I keep coming back to because it sets fruit even when temperatures are still a little high. Solar Fire is another great one that I’ve had amazing luck with. For cherry tomatoes, Sweet 100 is incredibly productive and the kids love snacking right off the vine.
I’d steer clear of heirloom varieties for your fall garden if you’re a beginner. They tend to be more sensitive to heat and disease. Once you’ve got a season or two under your belt, absolutely experiment with them, but for now, stick with the heat-tolerant hybrids and you’ll set yourself up for success.
Soil, Sun, and Watering Tips for Your Fall Tomato Garden in Florida
Florida soil is notoriously sandy and drains way too fast for tomatoes, which are heavy feeders and drinkers. I always amend my beds with a generous amount of compost before planting, and I mix in some slow-release fertilizer too. If you’re growing in containers (which I actually love for tomatoes!), use a high-quality potting mix rather than garden soil, which compacts too much in pots.
Tomatoes need at least 8 hours of full sun every day. In August, that’s obviously not a problem here in Florida! Just make sure you’re not planting somewhere that gets afternoon shade from a fence or tree.
Watering is where a lot of beginners struggle. Tomatoes like consistent moisture, and Florida’s summer rains can make that tricky. Too much water causes root rot and a disease called blossom end rot, which shows up as a dark, sunken spot on the bottom of your fruit. I use a drip irrigation system on a timer, and I check the soil moisture every day during dry spells. Stick your finger about an inch into the soil and water if it feels dry. Simple as that!

Dealing with Pests and Diseases Before They Become a Problem
Oh, the bugs. Florida gardeners know the struggle is real when it comes to pests. Tomato hornworms, whiteflies, aphids, and stink bugs are the main ones I battle every fall season. I check my plants every single morning because catching pests early makes all the difference.
For hornworms, I just pick them off by hand (yes, it’s gross, but it works). For whiteflies and aphids, a strong spray of water knocks them off, and neem oil spray works really well as a follow-up treatment. I try to keep things as organic as possible in my garden.
Disease is the other big challenge in Florida because our humidity creates perfect conditions for fungal problems like early blight and southern blight. The best prevention is giving your plants good airflow by not crowding them together. Space tomato plants at least 24 to 36 inches apart and stake or cage them so the leaves aren’t sitting on the soil.
Mulching around the base of your plants also helps a ton because it prevents soil from splashing up onto the leaves when it rains. I use about 3 inches of straw mulch and it makes a noticeable difference in keeping disease pressure down.
Starting your fall tomato garden in August is one of the best decisions you can make as a Florida gardener. With the right variety, good soil prep, and a little daily attention, you’ll be harvesting beautiful tomatoes by the time the rest of the country is dealing with frost.
If you’re new to this, please don’t feel overwhelmed! What to plant in Florida in August really comes down to getting the timing right and choosing varieties that love our climate. Start with one or two plants, learn as you go, and I promise you’ll be hooked on fall tomato gardening for life.
