Large, firm hearts with crisp texture and good flavour. May be overwintered or sown early under cloches or frames.
Sow & Grow:
Outdoors: sow thinly, March-July or September-October, where they are to crop, 1.5cm (½") deep, directly into finely-prepared, fertile, moisture-retentive soil, which has already been watered. Allow 30cm (1') between rows.
Early sowings may benefit from cloche protection. Seedlings usually appear in 7-21 days. Thin out to 25cm (10") apart. Water well until plants are established.
Regular sowings, made every two to three weeks, will ensure a continuous supply.
Harvest: April-October. September to October sowings will be ready the following April to May.
Hints & Tips:
It is possible to get an even earlier start in spring, by sowing under glass in February and planting out in April.
