A carrot pulled from light garden soil is crisp, sweet and far more satisfying than a bagged one. Carrots store well, and varieties are available in orange, purple, yellow and white.

When and how to sow

Carrots are hardy and are best sown directly, as their roots dislike disturbance. Sow from March to July in prepared soil, or make a later sowing in July for autumn and winter lifting. Use a cloche or fleece for very early sowings, especially in colder parts of the UK.

Care

Prepare deep, loose, stone-free soil to encourage straight roots, and keep it evenly moist while seedlings establish. Thin carefully in the evening, then water in, so neighbouring plants have room to develop without attracting carrot fly.

Common problems

Carrot fly and forked roots are common issues. Cover crops with fine mesh, keep it securely at ground level, and avoid bruising foliage when thinning. Remove stones and avoid freshly manured ground to reduce misshapen roots.

Harvest

Lift carrots once their shoulders have coloured and they are a useful size. A light frost can improve flavour. Loosen the soil with a fork before pulling, taking care not to damage roots intended for storage.
