Start peas indoors in guttering or deep modules to protect seeds from mice and get an early harvest. This method reduces root disturbance when transplanting.
Sow seeds in guttering or deep modules filled with compost 15th February - 2nd March. Space seeds about apart and cover with of compost. Keep at until germination, which usually takes 7–14 days.
Gradually acclimate seedlings to outdoor conditions over 7–10 days 15th March - 22nd March. Start with a few hours in a sheltered spot and increase exposure daily to prevent shock.
Dig a shallow trench and slide the entire block of seedlings from the guttering into the trench without separating plants 18th March - 1st April. Space rows apart and water well. Install pea sticks, trellis, or netting immediately to support the plants as they grow.
Cover the rows with fine netting or fleece to protect young shoots from pigeons and other birds. Check regularly for signs of mice and consider using cloches if needed.
Water heavily once flowers appear to help pods swell, aiming to keep the soil consistently moist. Apply a balanced liquid feed every 14 days to support growth.
Pick pods regularly 5th November - 24th May to encourage more flowers. For garden peas, harvest when pods are swollen; for mangetout, pick while pods are completely flat. Use scissors to avoid damaging the vines.
Plants that grow well (or poorly) with Peas
Companion planting can help deter pests, improve pollination, enhance growth, and maximize garden space. Some plants release chemicals that repel pests or attract beneficial insects, while others can improve soil quality or provide shade for sensitive plants.
Popular varieties of Peas to consider
A reliable early garden pea with sweet, small pods. It's resistant to mildew and good for cooler UK springs.
A mangetout variety with flat, tender pods that are best harvested young. It's vigorous and suits direct sowing.
A dual-purpose pea with edible pods that swell like garden peas. It's crunchy and sweet, needing regular picking.
