Outdoors: sow thinly March-May, 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 14-21 days. Water well until plants are established. Transplant when seedlings are about 10cm (4") tall, in rows 45cm (18") apart. Plant firmly and water well. Or sow indoors, March-May, 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 before planting out, during July-August, into well-cultivated, fertile soil. Harvest: September-March.
