Carrot is grown for its root, ready to pull about 70 days after sowing. It's hardy across USDA zones 2 through 11. Its summer flowers are a moderate draw for honeybees, native bees, and butterflies, even though the root is the prize. As a member of the carrot family, give it a fresh bed each year — away from where its relatives just grew — so the soil-borne pests and diseases of the family never get a foothold.

What Carrot is
Carrot reaches around a foot at maturity. It blooms white in summer.
How to grow Carrot
Carrot grows in USDA zones 2 through 11 and is ready to harvest about 70 days after planting. Carrot does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.2 to 8.7, on well-drained ground. It needs around 1,100 growing degree days to mature and a growing season of at least 40 frost-free days, which is why climate matters as much as soil.

Sow directly
Sow carrot seed straight into the bed — root crops germinate fast and resent transplanting. Give them full sun.
Match the soil
Carrot prefers pH 4.2 to 8.7 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at maturity
Carrot is ready about 70 days after sowing (UMass-Veg; Cornell). Pull while roots are young and tender — sweeter than oversized ones.
Where Carrot thrives
On hardiness alone, carrot grows across most of the country — its range (USDA zones 2 through 11) is unusually wide. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 2–11 spans average winter lows from -50°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 48 outright and splits 3 more down the middle — and which side of that line your land sits on changes the answer.

Where Carrot stands, state by state
Carrot is rated for zones 2–11 — a cold floor USDA puts at -50 to -40°F. Across the 50 states and DC, 48 sit fully inside that band, the line runs through 3 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

Before you harvest carrot, know your soil
Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant carrot for food. Our free screen reads 9 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.
Your land is one point inside Carrot's range
This page resolves to the species. Your state page draws the county line, and a report reads the parcel — the soil pH, drainage, sun, and frost dates on your exact ground, which no species average can see.

How we know this about Carrot
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Carrot in my zone?
Carrot grows in USDA hardiness zones 2 through 11 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Carrot take to grow?
Carrot is ready to harvest about 70 days after planting (UMass-Veg; Cornell). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Carrot?
Carrot is a cool-season crop, so it goes in during the cool halves of the year — early spring, and again in late summer for a fall planting — rather than at the height of summer heat. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Carrot need?
Carrot needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Carrot need?
Carrot prefers soil pH 4.2 to 8.7, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Carrot attract pollinators?
Yes — carrot's flowers are a solid nectar source for honeybees, native bees, and butterflies. (Source: Pollinator Partnership.)
Is Carrot safe for pets?
Carrot is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
