Sow late winter to mid spring at 21-24C (70-75F) on the surface of a good seed compost and gently firm down. Keep 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.
