How to Grow Carrots in Florida and the Warm US
Updated June 2026
Sandy Florida soil is actually great for carrots. The trick is keeping the seed moist while it slowly germinates.
Carrots are a cool-season root crop. Across Florida and the warm southern US they grow through the mild months from fall into late winter, when day length is shorter and the heat has eased. The loose, sandy soil that frustrates so many Florida gardeners is exactly what a carrot wants, because the root can push straight down without hitting clods or stones.
The single biggest factor in success is germination. Carrot seed is small and slow, taking one to three weeks to sprout, and the surface of the bed must stay damp the whole time. Get that right and the rest is easy. Sow direct, thin honestly, keep the water steady, and let the cool weather do the sweetening.
In cooler parts of the country carrots are a spring and fall crop instead. Use the climate selector in the tool below to see the sowing window that fits where you garden.

What it looks like as it grows
Position and soil
Carrots want full sun, at least six hours a day, and a deep, loose, stone-free bed. Dig or fork the soil to at least 10 inches (25 cm) and break up any clods. Florida sand is ideal as long as you add compost to hold moisture and feed the crop. Avoid fresh manure, which causes forking and hairy roots. A bed with too much nitrogen grows lush tops and stubby roots, so go easy on rich feed.
Sowing
Sow seed shallowly, about a quarter inch (6 mm) deep, directly in the bed. Carrots hate being moved, so do not start them in trays. Keep the surface constantly moist for the one to three weeks they take to germinate, this is the number one success factor. A light cover of burlap or a board can hold moisture until the first seedlings show, then remove it straight away.
Spacing and thinning
Sow more thickly than you need, then thin in stages. Thin first to about an inch apart once seedlings are a couple of inches tall, then thin again to between 1 and 2 inches so the roots have room to size up. Crowded carrots stay thin and twisted. Snip thinnings at soil level rather than pulling, to avoid disturbing the keepers.
Watering and feeding
Keep the bed evenly moist, never letting the surface dry out while seed germinates and never letting roots sit bone dry as they swell. Uneven watering causes split and cracked roots. A light feed of balanced fertiliser once the tops are established is plenty. Too much nitrogen grows leaves at the expense of root.
Pests and problems
Carrots have few serious pests in Florida. Root-knot nematodes can deform roots in infested sandy soil, so rotate beds, add plenty of compost, and consider a solarisation or cover-crop break in badly affected ground. Forking and splitting are almost always soil or watering problems rather than pests.
Harvest and storage
Start pulling from about 65 to 75 days, when the shoulders are roughly an inch across. Cool weather sweetens the roots, so they hold well in the ground through winter and you can harvest as needed. Twist off the tops after lifting and store roots in the fridge, where they keep for several weeks.
Varieties to grow
| Variety | Why grow it |
|---|---|
| 'Danvers 126' | Adaptable, handles heavier ground well. |
| 'Nantes' types | Sweet, crisp, blunt-tipped roots. |
| 'Little Finger' | Short type for containers and shallow beds. |
| 'Imperator' | Long roots for deep, loose soil. |
| 'Kuroda' | Heat tolerant, a good choice for the South. |
When to plant by region
This is a warm-US guide. The table below gives Florida sow windows. In other warm zones (USDA 8b to 11) grow carrots through the cool season. In cold-winter zones grow them as a spring and fall crop.
| Region | Sow direct |
|---|---|
| North Florida | Sep to Feb |
| Central Florida | Oct to Feb |
| South Florida | Oct to Jan |
| Cooler US zones | Early spring, and again late summer for a fall crop |

When should I plant carrots in Florida?
Carrots are a cool-season root in Florida. Sow seed directly from fall into late winter. North Florida sows September to February, Central Florida October to February, and South Florida October to January.
Why are my carrots forked or twisted?
Forking is caused by stones, clods, or fresh manure in the bed. Work the soil loose and stone-free to at least 10 inches deep and use finished compost rather than raw manure.
Can I grow carrots in containers?
Yes. Short varieties such as Little Finger or Nantes types do well in deep pots and shallow raised beds. Keep the mix loose and the surface evenly moist while seed germinates.
How long do carrots take to grow?
Most carrots are ready about 65 to 75 days from sowing, when the shoulders are roughly an inch across. Cool weather sweetens the roots and they hold well in the ground through winter.
Why won't my carrot seed germinate?
Carrot seed is slow and needs constant surface moisture for the one to three weeks it takes to sprout. If the top of the soil dries out the seed dies. Water lightly each day and consider a light board or burlap cover until seedlings appear.
How far apart should I thin carrots?
Thin seedlings to between 1 and 2 inches apart so the roots have room to size up. Crowded carrots stay thin and stunted.
Do I need to start carrots indoors?
No. Carrots resent transplanting and should be sown directly where they will grow. Direct sowing avoids root disturbance and gives straighter roots.
Can I grow carrots outside Florida?
Yes. In warm USDA zones 8b to 11 grow carrots as a cool-season crop in fall and winter. In cooler zones grow them as a spring and fall crop, sowing in early spring and again in late summer for a fall harvest.
