Sow from mid winter to late summer in a free draining compost, just covering the seed with silver sand. Seal in a polythene bag or cover with glass until germination which can take from 2-12 weeks. As this is a mixture, different types will germinate at different times. They will all germinate at 21 -24C (70-75P) but for most rapid results we recommend gradually raising the temperature over a period of 2 weeks from 14C (57P) to 30C (86F), when the large green seed leaf has been observed.
