Outdoors: sow thinly, March-June or September-October, in a seed bed, 1.5cm (½") deep, directly into finely-prepared, well-cultivated, fertile soil, which has already been watered. Seedlings usually appear in 14-28 days. Water well until plants are established. Transplant 60cm (2') apart, both ways, when plants are about 10cm (4") tall. Plant firmly and water well. Early and late sowings may benefit from cloche protection. Or sow indoors, January-March, 0.5cm (¼") deep, in a tray of compost. Water well and place in a cold frame or unheated greenhouse. Keep moist. Transplant 5cm (2") apart to other trays, when large enough to handle. Gradually accustom young plants to outside conditions (avoid frosts) before planting out, April-August, into well-cultivated, fertile soil. Harvest: June-October.
