Sow February to June or September to October on the surface of lightly firmed, moist seed compost in pots or trays. Cover seed with a light sprinkling of compost or vermiculite. 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 can take 14-30 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, 30cm (12 inches)apart.
For best results, provide a humus-rich, moist, well-drained soil in full sun or part shade.
