Outdoors, sow thinly, May-July, where they are to crop, 1.5cm (½") deep, directly into finely-prepared, rich, well-dug soil, which has already been watered. Allow 45cm (18") between rows. Seedlings usually appear in 14-21 days. Thin out to 25cm (10") apart. Water well until plants are established. Make two or three successional sowings to provide a crop throughout the winter. Harvest: October-March.
