Sow seeds on the surface of a good, free draining, damp seed compost. Then lighlty cover, 3mm (1/8in) deep with vermiculite or compost. Place container in a propagator or seal inside a polythene bag at a temperature of 25-30°C (77-86°F) until after germination which usually takes 10-42 days.
Transplant seedlings when large enough to handle, taking care not to damage the fragile roots, into 7.5cm (3in) pots. Pot on into a larger container each time roots fill the pot
