How to Sow and Grow Peas: A Complete Guide

Fresh peas reward early sowing with sweet pods that rarely reach the kitchen unchanged. They prefer cool growing conditions, a moisture-retentive soil and support from the beginning. The key is to match the sowing time to local weather rather than forcing seed into cold, waterlogged ground.

Choosing pea types

Shelling peas are grown for the peas inside, mangetout for flat edible pods and sugar snap peas for crisp, swollen pods. Dwarf varieties are useful in exposed gardens and containers; tall varieties crop over a longer period but need strong netting. Early, maincrop and mildew-resistant varieties extend the season.

When to sow peas

Sow in early spring once soil is workable. Make further small sowings every two to three weeks until early summer for continuity. In mild regions, hardy round-seeded varieties can be sown in autumn, but wet winters and mice often make spring sowing more dependable. In hot climates, treat peas as a cool-season autumn or winter crop.

How to sow

Choose a sunny to lightly shaded bed with fertile soil that drains well. Create a flat-bottomed drill about 5 cm deep and 15 cm wide. Space seeds 5–8 cm apart in two staggered rows, cover and water. Rows of tall peas should be at least 75 cm apart. Alternatively, sow in deep modules or lengths of guttering under cover and transplant before roots become crowded.

Protecting seed and seedlings

Mice and birds can remove seed before it emerges. Cover rows securely with fine mesh and press soil down gently after sowing. Slugs target young shoots. Use wildlife-safe barriers and regular evening checks. Remove mesh once plants are established unless pigeons remain a problem.

Supports

Install twiggy sticks, pea netting or wire before the tendrils need it. Dwarf peas may need 60–90 cm support; tall varieties can exceed 1.8 m. Keep netting taut and its lower edge close to the ground so stems do not collapse in wind.

Watering and feeding

Peas fix some of their own nitrogen, so rich nitrogen feeds are unnecessary. Compost added before sowing is usually enough. Water deeply when flowering starts and while pods swell, especially on light soil. Mulching reduces moisture loss. Avoid permanently wet ground, which causes roots and seed to rot.

Common pea problems

• Pea moth: sow early or cover crops with insect-proof mesh before flowering where this pest is common.

• Powdery mildew: choose resistant varieties for late crops and maintain moisture at the roots.

• Pea and bean weevil: scalloped leaf edges look alarming, but established plants often outgrow moderate damage.

• Pigeons: use secure netting with no loose sections that can trap wildlife.

• Poor germination: suspect cold wet soil, mice or old seed before resowing.

Harvesting peas

Pick shelling pods when they feel full but remain bright green. Harvest mangetout while pods are flat and sugar snaps when plump but crisp. Pick every day or two, using both hands to avoid pulling vines from supports. Regular picking encourages more flowers.

After the crop

Cut plants at soil level and leave the roots to break down. Add healthy top growth to the compost heap. Follow with a leafy crop or green manure, keeping normal crop rotation in mind where soil-borne disease has been a problem.
