Sow the seeds approx. 3-4 weeks before you intend to plant out 1cm (½in) deep in a good seed compost. Germination usually takes 6-10 days at 24C (75F).
Transplant when large enough to handle into 7.5cm (3in) pots. They need a warm, fertile soil with a soil temperature of 22-25C (70-75F) to flourish. Cover the soil 3-4 weeks before planting with a plastic mulch. Plant in single rows after all risk of frost has passed and the soil is warm 50-90cm (20-36in) apart and 2-2.5m (6-8ft) between rows, pulling a little soil around the plant to keep it from touching the plastic mulch. Water well after planting until established and dig a shallow water trench either side of the row for watering purposes.
