Outdoors October-November or February-May, where they are to crop, 5cm (2") deep, directly into finely-prepared, well-cultivated, fertile soil, which has already been watered. To make the best use of space, sow seeds 23cm (9") apart, in a wide row in a zigzag pattern, leaving a space of 60cm (2') between each row. Seedlings usually appear in 10-18 days. Water well until plants are established. Successional sowings will ensure a continuous supply and longer harvest. Or sow indoors February-April, 2.5cm (1") deep into individual pots of compost. Water well and place in a warm position. A temperature of 15-20°C (60-68°F) is ideal. Gradually accustom plants to outside conditions (avoid frosts), before planting out 23cm (9") apart during April-May. Harvest: June-August.
