When to sow
February to April
Where to sow
Sow seed on the surface of good, free-draining seed compost in pots or trays. Cover with a very fine sprinkling of compost or vermiculite. Place in a propagator or a warm place at a temperature of 20-25°C (68-77°F) until after germination which usually takes 7-21 days. Do not exclude light as this helps germination.
What to do next
Transplant seedlings when large enough to handle into pots or trays. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 30cm (12") apart.
