Sow & Grow:

Outdoors: sow thinly, March-July, where they are to crop, 1.5cm (½”) deep, directly into finely-prepared, well-dug, fertile soil, which has already been watered. Allow 15cm (6″) between rows. Early and late sowings may benefit from cloche protection. Seedlings usually appear in 14-21 days. No thinning is required, but keep well watered in dry spells. Regular sowings, made every three weeks, will ensure a continuous supply. Harvest: May-December.
