Outdoors: sow thinly March-September, where they are to crop, 2.5cm (1") deep, directly into finely-prepared, well-drained soil, which has already been watered. Allow 30cm (1') between rows. Early sowings may benefit from cloche protection. Seedlings usually appear in 14-21 days. Water well and ensure soil remains moist to prevent plants running to seed. Harvest: May-October. Harvest unthinned as baby leaves. Take a few from each plant, allowing them to regrow for two or three more pickings. Or thin to 15cm (6") apart to produce mature leaves.
