Florida’s Fall “Second Season”
Florida gardeners get something many other regions don’t: a fall growing season that can rival spring in productivity. As summer’s intense heat and humidity gradually ease, a wide range of cool-season crops become viable again, often running from around August into December depending on where in the state you garden. Roughly speaking, once daytime highs settle below the mid-80s°F on a consistent basis, many cool-season crops start to perform noticeably better.
Why Region Matters: North, Central, and South Florida
Florida’s north-to-south length means fall arrives at different times depending on where you are. North Florida tends to see cooler weather, and frost risk, earlier than Central Florida, which in turn cools down before South Florida, where many areas are effectively frost-free most years — a climate where, as this guide to vegetables that grow year-round explains, cool-season crops can often keep going outdoors through most of the winter with little protection. Because of this spread, the planting windows below are general tendencies — if you’re in South Florida, you can often start a bit later and keep going longer; if you’re in North Florida, it’s worth leaning toward the earlier end of each window.
What Vegetables Are Suitable for Fall Planting in Florida
Commonly recommended choices for a Florida fall garden include:
- Leafy greens and brassicas: lettuce, kale, collard greens, broccoli, cauliflower, cabbage, Brussels sprouts, arugula
- Root vegetables: carrots, radishes, beets, turnips, and short-day onion varieties suited to Florida’s latitude
- Legumes: southern peas earlier in fall, with snap/snow peas often planted once temperatures cool further
- Warm-season holdovers (early fall only): tomatoes, peppers, cucumbers, and green beans can sometimes still be planted in the earliest part of fall in some areas, though they generally need warmer soil than the cool-season crops above
Approximate days to harvest can help with planning: lettuce varieties are often ready in around 45–60 days, while carrots typically take longer, often in the range of 70–80 days depending on variety.
August–September: Starting the Fall Garden in the Heat
Despite the heat and the overlap with Florida’s peak hurricane season, August and September are typically when the fall garden gets started:
- In South Florida, seed-starting can often begin as early as mid-to-late August.
- In North Florida, many gardeners wait until early September, when conditions are a bit less extreme.
- Because late-summer heat can stress young seedlings, starting seeds indoors or in a shaded area — and gradually acclimating transplants to full sun — is a common approach.
- September is often considered one of the better months to direct-sow cool-season seeds like lettuce, spinach, and radishes, as the first real relief from summer heat typically arrives.
October: Direct Sowing Roots and Greens
By October, most of Florida is transitioning more fully into the cool season and into its dry season, which means consistent watering of new plantings becomes more important even as temperatures drop. This is typically a good window to:
- Direct-sow root vegetables and cool-weather greens like carrots, beets, radishes, lettuce, and spinach
- Transplant brassicas such as broccoli and cauliflower outdoors
- Continue succession plantings of kale, collards, and turnips
November and Beyond: Settling Into Cool-Season Growing
November is often cited as one of the most reliable months for Florida fall/winter gardening, with above-normal temperatures in many years still allowing cool-season crops, herbs (dill, parsley, cilantro), and more lettuce, broccoli, and peas to go in. Some sources suggest cool-season crops perform best when planted from mid-October onward, with peas specifically often held back until the heat has dropped further — though this can vary by region and by year, so it’s worth watching your local forecast rather than planting strictly by date.
Preparing Soil for Fall Planting
Florida’s sandy soils in many areas don’t hold moisture or nutrients especially well, which makes soil prep a meaningful step before fall planting:
- Clear out spent summer plants and any obviously diseased material.
- Work in organic matter — compost, aged manure, or a soil conditioner — to improve water retention and feed soil life.
- Consider a soil test through your county extension office if you haven’t amended in a while, since Florida soils can vary widely in pH and nutrient levels by location.
- Mulch after planting to help regulate soil temperature and reduce moisture loss, which is especially useful once the dry season sets in around October.
If you’d like a broader framework for timing based on frost dates rather than a specific state, see this fall vegetable planting guide by hardiness zone. Gardeners dealing with similar late-summer heat before a fall start may also find the fall vegetable gardening guide for Louisiana a useful comparison.
FAQ
What vegetables are suitable for planting in the fall in Florida? Leafy greens and brassicas (lettuce, kale, collards, broccoli, cauliflower), root vegetables (carrots, radishes, beets, turnips), and legumes like southern peas are all commonly grown in a Florida fall garden, with timing shifting by region.
How do I prepare soil for planting? Clear out old summer plants, work organic matter into the soil to improve structure and moisture retention, consider a soil test if you’re unsure of your pH or nutrient levels, and mulch after planting to help regulate soil moisture and temperature.
What is the 70/30 rule in gardening? This term isn’t used consistently across sources — some apply it to the balance of hardscape versus planted area, others to watering or light exposure splits. We don’t have strong enough grounding to state one definition as fact here, so it’s worth checking the context where you saw the term.
What vegetables can grow in 2 months? Many lettuce varieties, radishes, spinach, and some quick greens can mature in around two months or less, while root crops like carrots typically need longer — often 70 days or more.
