Carrots Growing Tips

Planting Carrots Plant Family: Apiaceae

Carrots are not hard to grow as long as they get enough sun light and cool temperatures around 65 degrees F. They are members of the Apiaceae family, which also includes celery, fennel, dill, parsley, parsnip, cumin, coriander/cilantro, and caraway.

Planting Dates

Planting Dates:

Best planting time is between: Jan-Mar or Aug-Sep

Space Between Plants

Space Between Plants:

Plants should be spaced from each other by 2 ft.

Space Between Rows

Space Between Rows:

Plants should be spaced from each other by 2 to 3 in.

Planting Depth

Planting Depth:

To plant seeds you should dig to a depth of ½ in.

Days to Harvest

Days to Harvest:

Your plant should be ready to harvest in 70-80 days

Step 1

Step 1 Plant your seeds outdoors 3 to 5 weeks before the last sping frost date in a loose, rock-free soil. If you have heavy soil, add plenty of aged manure. Plant again every 2 to 3 weeks after that. Carrots will take 70 to 80 days to mature, so plant your last planting 2 to 3 months before the first expected fall frost. In Zone 8 and warmer, plant carrots in fall or winter.

Step 2

Step 2 For easier weeding, plant your carrots in rows. Put a pinch of about 5 seeds per 1 inch. They will take 1 to 3 weeks to sprout. Cover with ¼ to ½ inch of screened compost, potting mix, or sand—a little more in warm, dry areas—to make it easier for the delicate seedlings to emerge. Water gently to avoid washing seeds away; keep the soil continuously moist for best germination.

Step 3

Step 3 Start thinning the seedlings to 1 inch apart when the tops are 2 inches high, and be thorough, because crowded carrots will produce crooked roots. Thin again 2 weeks later to 3 to 4 inches apart.

When to Water

When to Water Carrots require about 1 inch of water per week to reach their full potential. A slow, deep soak is the best method.

Cold Hardiness

Cold Hardiness Carrots are cold-hardy and make a good fall crop. In some areas, they can be overwintered, and there are some varieties bred particularly for overwintering.


Enemies The biggest threats to carrots are deer, gophers, woodchucks, and rabbits. Also Cutworms (curled caterpillars) can cut plants off at the soil line, chew 1/4" holes in pods or seeds, and occasionally chew leaves. Wireworms can feed on the carrot root. Here is a list of other pests: Aphids, Carrot rust fly, Darkling beetles, Flea beetles, Garden symphylans, Grasshoppers, Nematodes, Seedcorn maggot, Vegetable weevil, and Whiteflies.

Soil Type

Soil Type Light, sandy soil enriched with lots of organic matter and deeply tilled. Carrots grow best in rich, loose, sandy loam soil that is well drained and fertile. Before planting carrots, remove all rocks, and weeds from the planting area and till the soil to a depth of 8 to 12 inches.

Plant Height

Plant Height Carrots can reach a height of 1 to 3 feet.Take that into consideration when planning your garden. Make sure there is enough distance between your tall vegetables and short vegetables. That way both will get enough sun light.


Harvest Carrots will be ready to harvest in about 70 to 80 days, when the carrot is about 1 to 1½ inches in diameter. Carefully remove the carrot by reaching into the dirt around the outside of the carrot and gently pulling it out. Carrots planted in the summer may be left in the soil until the first killing frost.

Climate Type

Climate Type Carrots are cool-weather vegetables, so start sowing about 2 weeks before the last expected frost in your area.


Fertilization Carrots prefer a soil pH between 5.8 and 7.5. Before planting fertilize well. After the seeds sprout, Fertilize your plants once a week.

Tips 1

Tips 1 Careful attention to the soil makes these Vitamin A-rich roots a snap to grow. Plant in deep, stone-free soil (a raised bed is great) with a fine surface. Thin and weed carefully, and mulch to keep soil cool.

Tip 2

Tips 2 Keep the garden free from weeds, as weeds will compete with the growing carrots for soil nutrients and water. Do not dig too deeply when weeding and pull weeds carefully to avoid damaging the carrots root.

Tip 3

Tips 3 Carrots are biennial plants, grown as annuals. The first year, they store energy in their roots. Then the next spring, they leaf out quickly and send up a flower stalk.

Sun Light

Sun Light Carrots are a full-sun plant. While they tolerate partial shade, carrots require at least six to eight hours of direct sunlight during the day. 


Incompatibles Anise, Dill, and Parsley should not be planted next to carrots.


Companions The following vegetables will do well when planted next to carrots: Beans, Lettuce, Onions, Peas, Radishes, Rosemary, Sage, and Tomatoes. Planting certain vegetables next to each other can deter insects and encourage growth.

Crop Rotation

Crop Rotation "Next year, DO NOT plant carrot, celery, fennel, dill, parsley, parsnip, cumin, coriander/cilantro, and caraway in the same location where you planted carrots this year. Because they are all members of the Apiaceae family. Instead use that spot to plant other vegetables from a different family such as:

  • Allium (Amaryllidaceae) - onions, garlic, leeks, shallots and chives.
  • Legume (Leguminosae): peas, beans, lentils.
  • Mustard/Brassica (Cruciferae): broccoli, caulifower, kale, cabbage, Brussels sprouts, turnips, radishes.
  • Sunflower (Compositae): lettuce, artichokes.
  • Cucurbit (Cucurbitaceae): pumpkins, melons, squash, gourds, cucumbers.
  • Nightshade (Solanaceae): tomatoes, potatoes, eggplant, peppers.
  • Goosefoot (Chenopodiaceae): spinach, Swiss chard, beets.
When vegetables such as carrots are grown in the same garden space year after year, harmful microbes in the soil that are specific to individual plant families can build up. Additionally, there are vegetables which add nitrogen to the soil and other vegetables which take nitrogen from the soil. Rotating your crops can keep your soil balanced, not too rich or too poor in nitrogen."
