Sweet Pea Seeds 'Prima Donna'

Sweet peas are a beloved UK garden favourite, offering a kaleidoscope of colours and delightful fragrances from May through September. Their climbing habit makes them ideal for trellises, borders, wigwams, or even cascading over shrubs. With a little preparation, sweet peas are easy to grow and make excellent cut flowers for your home.

Indoor Sowing
Sow seeds in pots filled with quality seed compost during October–November or late January–April. To aid germination, soften seeds by placing them on a damp towel or in vermiculite until they swell. Tough seeds can be lightly nicked opposite the ‘eye’ to let moisture in. Place pots in a warm greenhouse, conservatory, or cold frame, keeping soil moist but not waterlogged.

Planting Out
Harden off seedlings before transplanting to a sunny, sheltered spot with well-drained soil enriched with compost or manure. Plant around 10 inches (25cm) apart, securing each to canes or a wigwam. Regular watering during dry periods supports healthy growth and abundant blooms.

Care and Maintenance
Encourage strong, bushy plants by pinching out the top of main shoots when around 4 inches (10cm) tall. Feed with a potassium-rich liquid fertiliser to boost flowers and tie plants gently to supports as they grow. Dead-head faded flowers throughout the season to prolong flowering and maintain plant health.
