When to Plant Carrots in North Carolina

Last reviewed by GardenSproutly against the sources listed on this page.

Carrots are a cool-season root crop. Sow them directly in the garden, because transplanting easily damages the young taproots.[1]

Carrot seed can take up to 3 weeks to germinate, so it can go in before your last frost date.[1]

How to plant
Direct seed in the garden[2],[3],[4]
Days to harvest
75–80 days from seed[3]
Seed depth
¼ in.; thin to 2–3 in. apart[1]
Soil temperature
At least 40°F for seed germination[5]
Soil
Moist, neutral to slightly acidic sandy loam[1]

Preparing soil for carrots

Carrots grow best in full sun but tolerate partial shade. They prefer moist, neutral to slightly acidic sandy loam. Heavy, compacted, poorly drained clay can make roots branch and twist.[1]

Before planting in beds or the ground, work 2 to 3 inches of compost into the soil and have it tested through the NC Department of Agriculture & Consumer Services. Go easy on fertilizer, because too much nitrogen pushes growth into leaves instead of roots.[1],[6]

Sowing carrot seed

  • Sow seed ¼ inch deep and thin seedlings to 2 to 3 inches apart.[1]
  • In fall, plant seeds about 1½ to 2 times deeper than you would in spring.[6]
  • Carrot seed is tiny. Tap it from a torn corner of the packet or mix it with dry sand to spread it thinly.[6]
  • A crust on the soil surface can stop seedlings from emerging. Mixing 2 to 4 inches of organic matter into the soil and watering with a soaker hose instead of a sprinkler helps prevent crusting.[6]
  • Row covers can protect young seedlings from extreme heat.[1]

Watering

Keep the soil moist. Check moisture several inches down rather than just at the surface, because under-watering leads to tough, bitter carrots.[1]

Carrots also grow in containers that hold at least 2 quarts and are at least 10 inches deep.[1]

Harvesting carrots

Roots reach maturity in 70 to 120 days depending on the cultivar and conditions.[1]

Harvest when roots are ¾ inch to 1 inch across. The largest roots generally have the darkest tops. Mulched fall carrots can stay in the ground all winter and be dug as needed.[6]

Common problems

Carrot yellows, Alternaria leaf spot, and root-knot nematodes can stunt or wilt plants. Powdery mildew can affect leaves, and root rot can affect seedlings. Insect pests include aphids, carrot rust fly, leafhoppers, flea beetles, leaf miners, weevils, caterpillars, and slugs.[1]
