When to plant carrots in Florida.
Sow between Dec 27 to Jan 29 in a typical year, keyed to Florida's median last frost around Feb 3. A second, fall sowing fits Sep 19 to Oct 15. Dates below are state medians; your ZIP code shifts them by days to weeks.
The 2026 windows
Carrots dates for a typical Florida season.
Direct sow
Dec 27 to Jan 29
Keyed to the ~Feb 3 last frost. Sow 0.25" deep, 2" apart.
Fall round
Sep 19 to Oct 15
Counted back from the ~Dec 15 first frost.
Harvest
~68 days later
~0.2 lb per plant over ~2 weeks.
Florida spans more than one climate: Zone 9 is the most common zone, but the state runs 8b to 11a. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
Florida growing notes
Florida sand grows a straighter carrot and a hungrier one.
The shape is a gift, the fertility is not
Florida's sandy soil, especially through the central ridge and coastal areas, gives a carrot almost nothing to push against underground, so a full-length Imperator or Nantes type runs straight down without the forking or stubbing that a clay-heavy garden further north deals with constantly. That same sand, though, holds almost no nutrients on its own, draining rainfall and any fertilizer applied straight through the root zone within days rather than holding it where the plant can use it.
The fix is to feed lightly and often rather than counting on one heavy feeding at planting time the way a clay-soil gardener might: work two to three inches of compost in before sowing to add some water and nutrient holding capacity, then plan on a second light feeding partway through the root's growth rather than trusting the sand to hold what you put down at the start.
Twelve rounds means the calendar, not the variety, is the real strategy
The window here supports twelve separate carrot sowings, more rounds than most of the country gets, which reflects how much of the Florida year actually stays cool enough for this crop rather than any special trick to the variety choice. Carrots germinate at a soil temperature of 40 to 45 degrees at minimum and grow best in the 55 to 70 degree range, and Florida's mild winter holds that range across a much longer stretch of the calendar than a summer-planted carrot further north ever gets.
Summer itself is the one closed door: soil running well above that optimum range through Florida's hottest months stalls germination and pushes any carrot still in the ground toward bitterness rather than sweetness. Treat the hot months as an off season for this crop entirely and put the twelve available rounds into the stretch on either side of it instead of trying to force a summer planting through.
Parsleyworm shares the same sandy bed
Parsleyworm, the green and black striped caterpillar that turns into a black swallowtail once it pupates, works over carrot foliage across Florida's long growing season, and the state's mild climate supports more generations here than a shorter-season garden ever sees, since the adult butterfly keeps laying eggs later into the year. A weekly check of the foliage and hand-picking any caterpillar found keeps a planting from losing more leaf area than the root underneath can afford.
Carrot rust fly, listed alongside it here, is a cooler-climate pest that struggles to build much of a population in Florida's warmth, so it is worth watching for without expecting it to be the main problem the way parsleyworm and aphids typically are. Aphids cluster on new foliage during any humid stretch, and a firm water spray every few days usually knocks a small colony down before it grows into a real threat to root growth.
In Florida: watch for
The pests that find carrots here.
With about 315 frost-free days, carrot spends longer in the ground here than in most of the country, which widens the window in which carrot rust fly can find it. Scout weekly from midseason and act on the first signs.
Rusty tunnels in the roots and stunted tops.
Organic fix: Cover the row; rotate away from last year's carrots.
Big green-and-black striped caterpillars on the foliage.
Organic fix: Handpick (or leave for swallowtails); Bt if heavy.
Brown spots ringed in yellow on the oldest leaves first, darkening until the tops look scorched.
Organic fix: Water at the base rather than overhead, turn under old carrot tops, and leave 2 years between carrot crops.
Your season math: Florida gives carrots about 315 frost-free days, and it needs roughly 68 days to a first harvest. That fits about 12 re-sown rounds across the season, so you can keep it coming instead of picking once.
Planting carrots in Florida: questions
When should I plant carrots in Florida?+
In a typical Florida year, sow carrots between Dec 27 to Jan 29, keyed to the state's median last frost around Feb 3. There's also a fall window: Sep 19 to Oct 15. Your exact dates shift with your ZIP code and microclimate.
What USDA zone is Florida?+
Florida spans zones 8b–11a, mostly zone 9. But frost dates, not zones, set planting time. The free planner uses your ZIP code's actual frost dates.
How many carrots plants do I need?+
Depends who you're feeding. The crop page has exact counts per household size, or the free planner does the math for your family in about 60 seconds.
