Carrots are easy to grow; just give them loose, rich soil free of clods and stones and a soil temperature anywhere between 45° and 85°F. That means you can grow carrots just about any time of the year in raised beds or containers—even in winter with the protection of a plastic tunnel.

Short and finger-size carrots that mature in as few as 50 days are ideal for all-year-round growing in home gardens; choose from these short, round, and fingerling varieties: Amsterdam ‘Minicor’ (ready in 55 days), Chantenay ‘Red Cored’ (ready in 70 days), ‘Nantes Half-Long’ (ready in 70 days), Nantes ‘Touchon’ (ready in 65 days), ‘Parmex’ (ready in 50 days), and ‘Thumbelina’ (ready in 60 days).

Carrots are slow to sprout and will benefit from a bit of protection early on. Use strips of burlap to protect seeds from birds and heavy rains until they sprout and begin to root. If temperatures drop below 40°F use spun poly row covers or plant blankets to protect beds and seedlings. Where freezing temperatures threaten or are common, grow carrots under the protection of plastic tunnels.

Sow carrots where you want them to grow; transplanting can cause carrots to grow forked and twisted. Once sown keep planting beds evenly moist to encourage quick sprouting and even and flavorful growth.

Five Easy Steps to Grow Carrots

Step 1: Prepare the planting bed. A raised bed or a half-barrel or other container filled with planting mix make a good home for carrots. Prepare the planting bed by turning the soil to a depth of at least 12 inches. If your soil is heavy with clay, add sand and well-aged compost to the bed and turn it under with a garden fork. Loose soil is best for carrot growing. Be sure to clear the bed of clods and stones which can cause carrot roots to fork or grow malformed.

Sprinkle bone meal across the bed, but don’t add manure to the soil bed before growing carrots. Bone meal is rich in phosphorus which encourages root growth; the nitrogen in manure will cause carrots to grow hairy roots. Water the bed deeply and let it sit a day or two before sowing carrots; you want evenly moist soil for fastest germination and growth.

Step 2: Sowing seeds. Carrot seeds are tiny; it is very easy to over-sow the planting bed or container. Mix carrot seeds with sand in the palm of your hand; this will make it easier to sprinkle seed across the bed—and you will know exactly where the seed has been sown. An alternative is to use pelletized carrot seeds that are easy to hold and sow one by one or seed tape—thin paper tape on which carrot seeds are evenly spaced. Pelletized seeds and seed tape will relieve you of having to thin seedlings later on.

Sow seeds thinly and evenly across the bed or down the row—eventually you will want to give each carrot an inch or slightly more to grow all around. Use the handle of garden hoe or rake to make a shallow trench to sow seed in rows. Rows next to weeping drip lines will ensure even moisture during the growing period. Cover seed lightly with ¼ inch peat moss or potting soil. Use the heel of your hand or a board to gently press down on the soil covered seed; this will ensure seeds make good contact with the soil which is essential for germination.

Step 3: Protect the seeds. Cover the bed with floating row covers to protect the shallow sown seed from the overhead drips of rain or irrigation that might uncover and expose the seed. Where the weather is hot and dry, use strips of burlap to cover the planting beds or rows (sprinkle the burlap with water to keep the seedbed just moist until seeds sprout). Be sure to look under your protective cover every day or two; when seeds sprout remove the burlap. Floating row covers can remain in place—particularly if temperatures dip below 40°F in your region.

Step 4: Keep growing carrots moist and weed free. It is important to keep the planting bed moist until seeds sprout. Sprinkle the bed once or twice daily with fine spray for the first couple of weeks. Do not let the soil dry out.

Once carrots sprout continue to moisten the bed with a fine spray until they are well rooted. As roots begin to grow, water carrots deeply for continuous, even growth; deep watering means keeping the soil moist to just below the deepest root tip. Carrots and other root crops follow the moisture into the soil. When green tops begin to wilt, it is time to water. When the soil dries out to a depth of 3 inches, it is time to water. Even, deep watering will encourage carrot tap roots to grow straight down.

Eliminate weeds from carrot growing beds; weeds compete with carrots for soil moisture and growing space.

Step 5: Thin the seedlings and eat. Thin carrots to 1 inch apart to allow fullest root growth of neighboring roots. Thin carrots by gently lifting seedlings that are too closely spaced or cut off the tops at the soil level with garden scissors before tap roots begin to develop. You can eat the thinnings—just add them to salads.

Carrots are ready for harvest when they are big enough to eat—you are the judge. Baby carrots can be added to salads whole. Push soil away from the shoulder of carrot roots; once roots are ½ inch across or more, they will be sweet and tasty enough to eat.

  1. I live in the midwest. We regularly get a few month span if upper 20’s as our daytime high. Would a hoop over a raised bed actually provide enough extra warmth to grow carrots during the winter?

  2. I want to plant carrots now for harvesting sometime during the winter. I live just south of Phoenix, Arizona. Is there a specific variety of carrot seed that I should be looking for? They will be in raised beds and it does freeze where I live since we are out in the open desert (I am in a rural area).

    • For winter harvest, choose a carrot variety with a shorter–rather than longer–number of days to harvest. At the seed store compare the varieties for sale and choose one that will be ready in 50 to 60 days; these can be harvested as baby carrots in as few as 40 days.

  3. My friend is vegan and i am going to join her in becoming a vegan next year. We live in durban and go to a boarding school. We would like to ask you some questions on growing fresh crops in our back garden by the horse stables. Please help us ..

    • Carrots do best where there is full sun; however, if you are growing carrots in a very hot summer region they will likely prefer a few hours of of shade in the the middle of the day if possible. Late and early season carrots should get a full day of sun; the days are shorter that time of the year. Keep the soil just moist; not wet and don’t let it dry out.

  4. I’m want to know if I can grow carrots in the heat of summer around the end of June in Louisiana. I’m growing them in raised beds and is there any way I can improve their growth by cooling the soil in some way. Temperatures regularly surpass 90 F here.

    • The conditions you describe are not optimal for carrots. A better strategy would be to plant them at the end of summer and grow them into the cool time of the year. The only way to cool the soil in summer would be to place straw across the bed as insulation against heat; you can also create furrows off to the side of the planting mounds and water there; this will cool the soil somewhat but this is not an ideal strategy.

  5. Thank you so much for sharing these transformative tips with fledgling farmers of my kind. We will grow more and more carrots to encourage consumers to continue eating balanced diets.
