Peas are a classic cool-season crop, producing sweet pods while summer vegetables are still getting started. Early, maincrop, mangetout and sugar snap varieties offer different harvests, and even a short row can be highly productive in a small garden.

When and how to sow

Sow peas directly from March to June, when soil is workable, choosing an earlier sowing under cloches in mild areas. In colder northern gardens, wait until the ground is less wet and chilly. Sow in shallow drills, about 5 cm apart, then cover with soil. Protect seed from mice where necessary. Put pea sticks or netting in place at sowing time, before roots spread.

Care

Water during dry spells, especially when flowers and pods are forming, but avoid waterlogging. Guide tendrils on to pea sticks or netting and keep weeds down. Succession sow every few weeks until June for a longer season, choosing mildew-resistant varieties where possible.

Common problems

Mice may dig up newly sown seed, so use cloches or other physical protection until seedlings establish. Pea moth can affect later pods, while powdery mildew is common in dry summer weather. Earlier sowing, watering at soil level and good spacing reduce trouble.

Harvest

Pick shelling peas when pods are rounded but still bright green and tender. Harvest mangetout while pods remain flat, and sugar snaps when crisp and plump. Gather every few days, ideally before pods become tough, because frequent picking keeps plants cropping.
