Outdoors: sow thinly April-July, where they are to crop, 2.5cm (1") deep, directly into finely-prepared, well-drained soil, which has already been watered. Allow 40cm (16") between rows. Seedlings usually appear in 14-21 days. Thin seedlings to 15cm (6") apart. Water well until plants are established. Regularly pick a few leaves and stems at a time, without stripping the plants, allowing them to continue growing. Harvest: July-November.
