Carrots: Planting, Growing, and Harvesting Carrots at Home

Carrot seeds can be sown about 2 to 3 weeks before the last spring frost date. Find your local frost dates here. Ideally, you want the soil to have dried out and warmed up a little after the winter.
- Seeds germinate after the soil temperature is at least 40° and germinate best at 55-65°, not exceeding 75°F. High summer temperatures reduce growth, decrease quality, and cause bitter or off-flavors to develop.
For a fall harvest, sow seeds in mid-to-late summer—starting about ten weeks before your first fall frost.

How to Plant Carrots

Prepare the site by tilling to a depth of 10 inches. We recommend double-digging to be certain.Make sure there are no rocks, stones, or even soil clumps. Amend soil with compost and 6 inches of sandy topsoil if your soil isn’t loose and airy.
We recommend sowing seeds directly in the garden (or wherever you plan to grow them) rather than transplanting. Carrots do not like to have their roots disturbed.
Sow 1/4 inch deep, 2 to 3 inches apart in rows 1 foot apart.
- Tip: Try to distribute seeds in an even fashion so that seeds don’t grow together. The seeds are pretty tiny, and it’s very easy to sow them too thickly. If you’ve not got the steadiest hand, then a simple tip is to mix the seeds with fine sand to spread the seeds out. You can then sow pinches of your sand-seed mix instead. Then, just cover the seeds over.
Keep the soil moist with frequent, shallow watering. For small carrot seeds to germinate, the soil mustn’t form a hard crust on top; covered with a layer of fine sand, vermiculite, or compost to prevent a crust from forming. (If you put your finger in the ground, it should be moist, but not wet, to the middle knuckle.)
Carrots are sometimes slow to germinate. They require 14-21 days to emerge, so don’t panic if your carrots don’t appear immediately!
Planting radishes with carrots helps minimize the crusting problem and helps you keep track of where the carrot seeds were planted. Sow quick-germinating radish seeds between carrot rows. The radishes will grow quickly, and by the time the carrots really start to grow, they can be harvested.
For a continued harvest, plant carrots every four weeks through mid-summer.

Carrots in Containers

Growing carrots in pots is a great way to customize the perfect growing medium and avoid pests like carrot flies. Pots must be at least 10 to 12 inches deep and wide.

A great low-fertility mix is one part sand and one part potting mix.
Sow seeds very thinly over the top of a filled pot and then cover them with just a touch more of the mix.
Water well, label, and set into a sunny position.
Keep everything moist because, unlike carrots in the ground, carrots in containers will be entirely dependent on you for all their needs.
Once the seedlings are up, thin them to a couple of inches apart. Then harvest them once they’ve reached finger size.

Growing

Gently mulch carrots to retain moisture, speed germination, and block the sun from hitting the roots directly.
When seedlings are an inch tall with 3 to 4 true leaves, thin so that they stand 3 to 4 inches apart. Snip tops with scissors instead of pulling them out to prevent damage to the fragile roots of the remaining plants.
Ensure carrots receive 1 inch of water per week, either through rain or watering; do not overwater carrots.
Weed diligently as carrots do not like struggling against weeks, but be careful not to disturb the young carrots’ roots while doing so.
Fertilize 5 to 6 weeks after sowing (We recommend a low-nitrogen fertilizer as excess nitrogen in the soil promotes top, or foliage, growth—not roots.). Learn more about how and when to fertilize your vegetables.

Growing Carrots in Containers

You can also grow carrots in containers! It is important to grow carrots in a container that is deep enough for them at maturity. For baby or dwarf carrots, a 6- to 8-inch-deep container is needed. Standard carrots need a depth of at least 12 inches, if necessary, to accommodate a particular variety’s length. Carrots are a cool-season crop usually grown in the spring; seeds can be sown 2 to 3 weeks before the last spring frost.

Prepare a loose, well-draining potting mix with a portion of compost or organic matter. Add a handful of bonemeal; it contains phosphorus, which benefits root crops. Also, add low-nitrogen fertilizer, per the package directions, based on the container size. Water the soil evenly to moisten. Sow the seeds about a 1⁄2 inch apart and 1⁄4 inch deep. (Carrot seeds are tiny and thus difficult to drop individually; pelleted seeds or seed-taped ones are good alternative means.) Cover with a very light sprinkling of soil. Water gently (a handheld pump container is advised instead of a hose, the water force from which can displace the cover soil and seeds).

Water regularly to keep the soil moist. Container soils tend to dry relatively quickly. Dry soil can promote forking (misshapen roots).

When carrot tops are 2 to 3 inches tall, thin them to 1 1/2 to 3 inches apart, based on the carrot size at maturity, use scissors to cut off the tops, rather than pulling seedlings and disturbing the roots. Apply a low-nitrogen fertilizer every 3 to 4 weeks, per the package directions for the size of the container.

Harvesting

How and When to Harvest Carrots

How do you know when your carrots are ready? Have a little root around and check the approximate width of the roots by looking at the neck of the root. The first roots should be ready as soon as two months from sowing.

Generally, the smaller the carrot, the better the taste. Carrots should be about as wide as your thumb or at least ½ of an inch in diameter.
Younger and shallower roots should come away easily enough simply by gripping them firmly at the base of the foliage. It often helps to push down on the root first and then twist it as you gently pull upwards.
Larger, longer roots—particularly those of maincrop carrots that are sown for winter eating—may need to be eased up with the help of a fork.
Harvest in stages—or as roots reach full size. In this way, you’ll stagger your harvest over many weeks.
If you’re growing carrots in the spring and early summer, harvest before daily temperatures get too hot, as the heat can cause carrot roots to grow fibrous.
If you are harvesting in the fall, carrots taste much better after one or more frosts. (A frost encourages the plant to start storing energy—sugars—in its root for later use.) Following the first hard frost in the fall, cover carrot tops with an 18-inch layer of shredded leaves to preserve them for harvesting later.
Note: Carrots are biennials. If you fail to harvest and leave the carrots in the ground, the tops will flower and produce seeds next year.

How Do You Store Fresh Carrots?

To store freshly harvested carrots, twist or cut off all but 1/2 inch of the tops, scrub off any dirt under cold running water, and air-dry. Seal in airtight plastic bags and refrigerate. If you simply put fresh carrots in the refrigerator, they’ll go limp in a few hours.
You may leave mature carrots in the soil for temporary storage if the ground will not freeze and pests aren’t a problem.
Carrots can also be stored in tubs of moist sand or dry sawdust in a cool, dry area.

Pls can Goat or sheep eat carrot leaves. I want to plant them in my unfenced garden

I recently watched a video about growing carrots from carrot tops. Since then, I have read articles stating you cannot grow new carrots from the tops. I have a dozen beautifully re-sprouted carrot tops in a bowl that have 4-5 inches of new green on the top and the white roots on the bottom. Can I plant these in my garden for new carrots? Please clarify. Thanks!!!

Unfortunately, a new taproot won’t grow from the top of old carrot soaked in water. As you have seen, the tops will grow more leaves, and thin white roots will also grow, providing nutrients for the plant. The plant, over time, may even form flowers. But sadly, no new taproot will form to harvest. People still enjoy growing carrot tops for fun as an experiment, or to provide fresh greenery for an indoor display.

this is my first time doing a garden ..so i decided to start out with a small jon boat with carrots and tomatoes and onions.....as im looking the soil for my carrots does not look deep enough from them to grow a mature growth......Can i take them out and add more soil ? or do i just leave them in and see how well they will do as is?

Carrots usually need about 9 to 18 inches of soil depth, depending on the variety that you grow—check the seed packet, if you have one. For containers, the mini types are best — ones that grow short or in a ball-shape. As to moving them, carrots can be tricky. They have a long taproot that extends beyond the orange part; it is important to keep it intact. If your carrots are tiny seedlings at this stage, you might be able to carefully remove them from the soil, including a large and deep root ball, and then adjust the soil level. Some gardeners have had success with this at young seedling stage. But if the plants are more established, it would probably be best to keep them as is, unless the soil level is much under the required depth.

Hi I need some help I attempted to grow carrots in containers last year after 68 days no carrots I did chalk it up to gardener error as I transplanted them which is a no no.I recently decided to have a go at carrots again the chantenay variety. I took a pot added dirt sowed my seed in the dirt on Sept. 17the the germinated I thinned them they have come up beautifully. But the stems are still small they are growing in height. But I am worried they are not going to produce any carrots.
