Sow outdoors thinly, from March to July where they are to crop, 1.5cm deep, directly into finely-prepared, fertile, moisture-retentive soil, which has already been watered. Allow 30cm between rows. Early sowings may benefit from cloche protection. Seedlings usually appear in 7-14 days. Thin out to 25cm apart. Water well until plants are established. Regular sowings, made every two to three weeks, will ensure a continuous supply. Harvest from June to October.
