Sowing
Sowing time: March to April.Sow seeds in pots or trays of moist seed compost and cover with a fine sprinkling of compost or vermiculite. Place in a propagator or warm place, and keep at a temperature of between 20-25C (68-77F). 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 (3in) pots or trays.

More Info

Gradually acclimatise young plants to outdoor conditions for a few weeks before planting out after all risk of frost, 23-30cm (9-12in) apart. For best results, provide a light, well-drained soil in full sun.
