Sowing Time: February to June or September to October. Sow seed in pots or trays of moist seed compost. 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 usually takes 14-30 days.
When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost, 45cm (18in) apart. For best results, provide any ordinary, well-drained soil in full sun.
