How to grow pea
Overview
Pea (Pisum sativum) is a cool-season legume grown for its tender pods or protein-rich seeds. Regular picking encourages continued production, and the plant's frost tolerance makes it ideal for cooler months. Timing is crucial as heat causes poor pod set and rapid maturity.
Varieties
- Sugar Snap — A popular snap pea with edible, sweet pods; grows 1.5–2 m tall.
- Snow Pea — Flat, tender pods eaten whole; ideal for stir-fries and salads.
- Greenfeast — Classic shelling pea with high yields and excellent flavour.
- Telephone — Tall, vigorous climbing pea producing long, well-filled pods.
- Oregon Sugar Pod II — Disease-resistant snow pea with large, sweet pods.
Soil Preparation
Peas prefer well-drained, loamy soil rich in organic matter. Incorporate compost or well-rotted manure before planting. Aim for pH 6.0–7.0 and avoid heavy clay or waterlogged conditions.
Growing Guide
Sow seeds 2–3 cm deep, 5–10 cm apart in rows 50–60 cm apart. Provide trellis or netting for climbing varieties. Maintain consistent moisture without waterlogging. Ideal soil pH is 6.0–7.0. Sow in early spring or autumn depending on your zone; avoid hot weather.
Sowing
Sow seeds directly 2–3 cm deep, 5–10 cm apart in rows 50 cm apart. Germination takes 7–14 days. Soaking seeds overnight can speed germination but is not essential. Do not transplant as roots are sensitive.
Care
Apply a low-nitrogen organic fertiliser at planting and again when flowers appear. Pinch out growing tips after the main harvest to encourage side shoots. Train vines onto supports to keep pods clean and reduce disease risk.
Companion Planting
Peas grow well with carrots, radish, lettuce, and beans. Avoid planting near onions, garlic, or other alliums, which can stunt growth. Good companions benefit from the nitrogen peas fix in the soil.
Common Pests & Risks
Powdery mildew is common in humid conditions; improve air circulation and use resistant varieties. Aphids can be controlled with neem oil or insecticidal soap. Birds may peck pods; use netting or reflective tape. Monitor for slugs and snails on young seedlings.
Harvesting
Harvest pods when they are plump and bright green but before seeds become hard and starchy. For snow peas, pick when pods are flat; for shelling peas, when pods are round. Regular picking every 2–3 days extends the harvest.
In the Kitchen
Peas are sweetest when picked fresh; use within a few hours for best flavour. Blanch and freeze for longer storage. Add to stir-fries, salads, or steam and serve with butter. Snow peas are excellent raw in salads.
Troubleshooting
Yellow leaves: overwatering or nitrogen deficiency; improve drainage and apply organic fertiliser. Powdery mildew: poor air circulation or humid conditions; space plants and use fungicide. Poor pod set: heat stress; plant earlier or choose heat-tolerant varieties. Birds pecking pods: use bird netting. Seedlings eaten: slugs/snails; use iron phosphate baits.
