This variety produces large, firm hearts with crisp texture and good flavour. May be overwintered or sown early under cloches or frames. Sow outdoors thinly, from March to July or September to October, 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 7-21 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 April to October. September to October sowings will be ready the following April to May.
