Sow indoors, March-May. A warm kitchen windowsill is all you need for starting these seeds. Sow, 1.5cm (½") deep, in pots of compost. Keep warm and moist. A temperature of 15-20°C (60-68°F) is ideal. Seedlings usually appear in 7-21 days. Gradually accustom plants to outside conditions (avoid frosts), before planting out, May-June, into well-cultivated, fertile soil, when frosts are over. Plant in blocks and allow 40cm (16"), both ways, between plants, disturbing roots as little as possible. Or, sow outdoors, during May, 1.5cm (½") deep, two seeds together at 40cm (16") intervals in block formation. Sowings may benefit from cloche protection if temperatures drop. Thin to the stronger seedling when large enough to handle. Harvest: August-September.
