Daucus carota subsp. sativus
Carrots do best in a deep, light, stone-free soil with plenty of sun. Sow direct in short batches from late winter into early summer, thin carefully, and keep roots covered to help reduce carrot fly damage.

Grow outdoors in a fine, stone-free bed for the main harvest. This suits the usual UK garden sowing pattern and gives the longest picking season.
Choose a deep, well-dug patch and break the soil down to a fine tilth before 14th February - 4th April. Rake out stones and do not add fresh manure, as that can split and fork the roots.
Sow thinly in shallow drills around 14 Feb - 12 Jul, then cover with of fine soil and water in well. Sow a fresh row every 21 days for a steady supply rather than one large crop.
Cover the row with fine insect-proof mesh straight after sowing, from 14th February. Keep the edges sealed, since carrot fly can find gaps very easily.
When the seedlings are up, from 20th May, thin them carefully to apart so the roots can swell properly. Do it on a still day and water the row afterwards to settle the soil.
Start lifting roots from 8th July once they are large enough to eat. Pull them as needed through 8th July - 11th November, and maincrop roots can often stay in the ground longer if the soil is free draining.
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.
