How to Sow
Sow late winter to mid spring at 21-27C (70-80F) in a good seed compost. Sow seed on surface of compost and gently firm down compost. Keep soil damp but not wet. Do not exclude light, sealing in a polythene bag after sowing is helpful. Germination usually takes 10-21 days. When seedlings are large enough to handle, transplant and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 1-15 days before planting out after all risk of frost, 3cm (12in) apart in a sunny spot on light well drained soil.
