Sow March to April on the surface of lightly firmed, moist seed compost in pots or trays. Do not cover the seed. Keep at a temperature of between 15-20C (59-68F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 7-21 days. When large enough to handle, transplant seedlings into 7.5cm (3 inch) pots or trays. Gradually acclimatise young plants to outdoor conditions for 10-15 days before planting out after all risk of frost, 30-45cm (12 to 18 inches) apart.
