|---|
Soak the seed for 2 hours in lukewarm water before sowing. Sow at 18-24C (65-75F) in a good seed sowing mix. Sow the seeds on their edge and just cover with sowing mix. Keep soil damp but not wet, sealing in a plastic bag after sowing is helpful. Germination usually takes 21-30 days.
Growing Instructions
When seedlings are large enough to handle, transplant into 13cm (5in) pots, taking care not to disturb the roots and grow on in cooler conditions keeping them well watered. Gradually acclimatize to outdoor conditions for 10-15 days before planting out after all risk of frost 60cm (24in) apart in a sheltered spot in sun on ordinary well drained soil. For summer flowering under glass, transplant into 20-23cm (8-9in) pots, and keep the atmosphere fairly humid.
