How do I grow peas in a raised bed?

Sow seed straight into the mix and give climbing types a trellis to scramble up. Peas are legumes, so they don't need much feeding.

How often should I water and feed peas?

Keep the soil evenly moist, especially at flowering and podding. Water the soil in the morning to keep the leaves dry and mildew at bay.

What pests attack peas?

Keep an eye out for aphids, caterpillars, slugs and snails and thrips. Most are easily managed — see our safe pest guide.

What diseases affect peas?

The main ones are powdery mildew and downy mildew. Good airflow, morning watering and steady moisture prevent most.

What grows well with peas?

Carrots and beans are good companions; keep peas away from onions and garlic. See our companion planting guide.

When do I harvest peas?

Pick pods when they're plump but still tender, from the bottom of the plant up. The more you pick, the more they produce — and they're sweetest eaten straight away.
