If you’ve been waiting all summer for this moment, fall vegetable planting in Florida: what to plant in September is honestly the most exciting gardening topic I cover all year. September is when Florida gardeners finally get a break from the brutal summer heat, and our gardens come back to life in the best possible way. I look forward to this time every single year. Fall Vegetable Planting in Florida: What to Plant in September (tomatoes, Peppers, Leafy Greens & More) is a popular choice for gardeners.
The good news is that Florida’s fall season is incredibly generous. While the rest of the country is putting their gardens to bed, we’re just getting started with some of the most productive growing months of the year.
Fall Vegetable Planting in Florida: Getting Tomatoes and Peppers Started in September
Tomatoes are probably the vegetable I get the most questions about, and September is genuinely one of the best times to plant them here in Florida. You want to get transplants in the ground by mid-September so they have time to establish before temperatures really start to drop. I usually aim for the first two weeks of the month to give myself plenty of buffer.
For Florida, choose heat-tolerant varieties like ‘Solar Fire’, ‘Heatmaster’, or ‘Celebrity’. These were practically made for our climate and will set fruit even when temperatures are still warm. Plant them in a spot that gets at least 6-8 hours of sun daily and give them a good deep watering a few times a week rather than a little water every day.
Peppers are another fantastic choice for September planting. Both sweet bell peppers and hot varieties like jalapeños do really well in our fall weather. They love the warm soil and will reward you with a long harvest season that can stretch well into winter.
One thing I always remind people is to watch for aphids and whiteflies on your peppers and tomatoes. Florida’s warm weather means pests don’t disappear the way they do up north, so check the undersides of your leaves regularly. A simple spray of neem oil works wonders and won’t harm your plants.

This is where September planting in Florida really shines, and I could talk about leafy greens all day. Lettuce, spinach, kale, collards, Swiss chard, and arugula all absolutely love Florida’s fall conditions. The slightly cooler nights we start getting in September make these crops taste sweeter and grow faster than you’d expect.
I like to direct sow lettuce seeds right into the garden bed because they sprout so quickly you’ll see little green seedlings within a week. Scatter them thinly, cover lightly with soil, and keep them moist until they germinate. You can start harvesting outer leaves within about 30-40 days, which feels like instant gratification compared to some other vegetables.
Collards and kale are basically Florida fall garden staples. They’re tough, they’re productive, and honestly they just get better after a light frost. If you’re in North Florida (zones 8-9), you’ll definitely experience some cooler nights that make these greens taste even sweeter. South Florida gardeners in zones 10-11 can grow these all the way through February.
Spinach is a little pickier and really prefers soil temperatures below 70°F to germinate well. I usually wait until late September or even early October to sow spinach seeds, just to give the soil a chance to cool down a bit. Check out the UF/IFAS Gardening Solutions website for specific planting calendars based on your Florida region – it’s one of my go-to resources.
Root Vegetables and Herbs: More September Planting Options for Florida Gardens
September is also a great time to get root vegetables going, and this is something a lot of Florida gardeners overlook. Carrots, radishes, beets, and turnips all do beautifully in our fall weather. Radishes are my personal favorite for beginners because they’re ready to harvest in as little as 25-30 days. It’s such a satisfying quick win when you’re just getting started.
For carrots, make sure your soil is loose and deep – at least 12 inches. Florida’s sandy soil is actually great for carrots because it drains well and lets the roots grow straight down without hitting clay. Mix in some compost before planting to give them the nutrients they need.
Herbs are another September winner and honestly one of the most practical things you can grow. Basil is still going strong in early September, but you’ll also want to start planting cilantro, parsley, dill, and chives now. Cilantro especially loves Florida’s fall temperatures and tends to bolt (go to seed too fast) in summer heat, so September is really its sweet spot. According to UF/IFAS Extension, cilantro grows best when daytime temperatures are between 50-85°F, which is exactly what we start getting in fall.
I keep a small pot of mixed herbs right outside my kitchen door and it makes cooking so much more fun. Fresh herbs are one of those things that taste dramatically better when you grow them yourself.
Soil Prep, Watering, and Keeping Your Fall Garden Happy
Before you plant anything, take a little time to prep your soil and it will make a huge difference in your results. Florida’s sandy soil drains fast, which is great for avoiding root rot, but it also means nutrients wash away quickly. I always work in a generous layer of compost before planting each season.
A balanced vegetable fertilizer applied every 2-3 weeks will keep your plants fed and productive. I like using a slow-release granular fertilizer at planting time and then supplementing with a liquid fertilizer as the season goes on. Your plants will tell you when they’re hungry – yellowing leaves are usually the first sign.
Watering in September can be a little tricky because we’re still getting some rain but it’s becoming less reliable. I aim to give my garden about 1-1.5 inches of water per week total, including rainfall. A simple rain gauge helps you track this without guessing. Mulching around your plants also helps hold moisture in the soil and keeps weeds down at the same time.
Don’t forget to check the USDA’s gardening resources for general growing guides that pair well with Florida-specific advice. Combining both gives you a really solid foundation for success.
September is honestly my favorite month in the Florida garden, and I hope this gets you excited to get out there and start planting. Fall vegetable planting in Florida: what to plant in September really does give you so many options that it can feel a little overwhelming at first – but just pick two or three things that excite you and start there.
You don’t have to do everything at once! Start small, enjoy the process, and before you know it you’ll have a beautiful productive fall garden that your neighbors will be asking about. Happy planting, friends!
