Moisten compost before sowing. Sow seed and cover with compost or vermiculite, keep moist and at a temperature 20-25°C. Germination can take up to a month but can be faster if seeds are soaked in cold water overnight before sowing. Prick out into single pots (3") and grow on in cooler conditions. Plant out in August - September.
