Use this for the earliest outdoor sowings under fleece or a cloche. It helps you get a jump on the season in a cool UK spring.
Work the soil to a fine tilth before 12th January - 5th April and remove every stone you can find. Avoid manured ground, because carrots fork easily in rich, freshly fed soil.
Sow seeds thinly in shallow drills around 12 Jan - 10 May, then cover with of fine soil and water in carefully. Early sowings often do best under fleece or a cloche to warm the ground a little.
Fit insect-proof mesh over the row straight after sowing, from 12th January. Keep it in place through the growing period so carrot fly cannot reach the crop.
Thin the seedlings carefully from 2nd April to apart once they are large enough to handle. Water lightly after thinning to settle the soil and reduce the smell that can attract pests.
Begin lifting usable roots from 21st May and keep picking through 21st May - 5th November. Early sowings may size up faster than expected, so check them regularly rather than leaving them too long.
Tap a plant to see why it works (or doesn't) with Carrot.
Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
