March to May
WHERE TO SOW
Sow in trays of moist seed compost and cover with a fine sprinkling of compost or vermiculite. Place in a warm place and keep at a temperature of between 20-25°C (68-77°F).
WHAT TO DO NEXT
Prick off glasshouse seedlings into trays when large enough to handle 10cm (4") apart. Gradually harden off before planting out in May 30-45cm (12-18") apart.
