Sowing Instructions

Sow February to June or September to October. Sow seed on the surface of lightly firmed, moist seed compost in pots or trays. Cover with a fine sprinkling of compost or vermiculite. Keep at a temperature of between 10-15C (50-59F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination can take 21-40 days. When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays.

Growing Instructions

Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost,60cm (24in) apart.

Aftercare

For best results, provide a sunny, sheltered site and a deep, fertile, well-drained soil.
