Sow from late winter to spring in a good seed compost just covering the seed with compost and gently firm down compost and seal inside a polythene bag after sowing. Germination usually takes 10-20 days at 20-25C (70-75F). When seedlings are large enough to handle, transplant and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 10-15 days before planting out, after all risk of frost, 60cm (24in) apart in a sunny spot on light well drained soil.
