A homegrown carrot pulled from loose soil is crisp, sweet, and a world apart from the bagged kind. They store well and come in a rainbow of colors.

When and how to plant

Carrots are cool-season and cold-tolerant, sown directly a few weeks before the last frost as the dates above show, since the roots resent transplanting. They can also be sown for a fall crop.

Care

Loose, stone-free soil and even moisture give straight, well-shaped roots. Thinning the seedlings gives each carrot room to size up.

Common problems

Carrot rust fly and forked roots in rocky soil are the usual issues. A fine row cover and deeply worked beds solve most of it.

Harvest

Pull carrots once they have colored up and reached a usable size; a light frost sweetens them. Loosen the soil first so the roots come up whole.

Popular Carrots varieties to grow

Choose carrots by root length, soil type, and intended use, fresh eating, storage, or baby harvests. Heavy or shallow soils favor shorter roots, while deep loose beds allow long Nantes and Imperator types to size up well.

Growing Carrots in containers

Carrots are excellent container crops when the pot is deep enough for the selected root type. Use loose, stone-free potting mix in a container at least 10 to 12 inches deep for short varieties, or 16 inches or deeper for longer carrots, with drainage holes. Keep soil evenly moist for germination and root growth, avoid heavy feeding, and choose short Nantes, Chantenay, or round varieties for pots.

Watering & feeding Carrots

Provide about 1 inch of water per week, increasing toward 1.5 inches in hot, dry weather or sandy soil. Carrots have average water needs, but shallow-rooted seedlings need especially consistent moisture. Water gently and often enough to keep the seed zone moist until germination, then water deeply to moisten the root zone without leaving it soggy. Water at the base in the morning, use mulch after seedlings are established, and watch for wilting or slow growth from drought and yellowing, soft foliage from excess water.

Carrots are light to moderate feeders and grow best in loose, compost-amended soil with moderate phosphorus and potassium. Avoid fresh manure, heavy compost applications, and high-nitrogen fertilizer, which can encourage forked or hairy roots. Work finished compost and a balanced, low-nitrogen vegetable fertilizer into the soil before planting if soil fertility is low. A light side-dressing after seedlings are established can help poor soils, but stop if tops are lush and roots are not sizing up. Keep the top inch of soil consistently damp until seeds sprout, which may take two to three weeks. Thin seedlings promptly so each root has room to develop.

Saving Carrots seeds

Save seed from open-pollinated or heirloom carrots, not F1 hybrids, and isolate flowering carrots from Queen Anne's lace and other carrot varieties to avoid crossing. Carrots are biennial, so select sound roots, overwinter them in mild areas or store and replant them in spring, then let the second-year umbels turn brown and dry. Cut dry umbels into a bag, rub out the seed, dry it well, and store cool and dry for about 3 years.

Carrots companion plants

Good companions for carrots include onions, chives, garlic, lettuce, and radishes. Alliums are commonly used near carrots to help disrupt carrot-fly host finding, while lettuce and radishes use space without heavily competing with the deepening carrot roots. Avoid growing carrots immediately beside mature fennel, whose vigorous roots and foliage compete for water, nutrients, and light.
