When to sow
WHEN TO SOW
February to April
WHERE TO SOW
Sow seeds on the surface of lightly firmed, moist seed compost in pots or trays. Cover the seed with a very fine sprinkling of compost or vermiculite and place at a temperature between 15-20°C (59°F). Keep the surface of the compost moist but not waterlogged; germination will usually take 30-90 days. When large enough to handle, transplant seedlings into 7.5cm (3") pots or trays.
WHAT TO DO NEXT
Gradually acclimatise plants to cooler conditions for a few weeks before planting out after risk of frost, 30cm (12") apart. For best results provide a rich, light well-drained soil in full sun. Plants will prove hardy if wet winter conditions are avoided.
