Heavy, solid heads with compact habit can be sown closely together. Traditional favourite.
This is most definitely a cabbage for all seasons, supplying a good source of vitamin C and antioxidants through the year.
Outdoors: sow thinly, March-May, in a seed bed, 1.5cm (½”) deep, directly into finely-prepared, well-cultivated, fertile soil, which has already been watered. Seedlings usually appear in 14-21 days. Water well until plants are established. Transplant 40cm (16″) apart, when plants are about 10cm (4″) tall. Allow 30cm (1’) between rows. Plant firmly and water well. Or sow indoors, March-May, 0.5cm (¼”) deep, in a tray of compost. Water well and place in a cold frame or unheated greenhouse. Keep moist. Transplant 5cm (2″) apart to other trays, when large enough to handle. Gradually accustom young plants to outside conditions (avoid frosts) before planting out, May-June, into well-cultivated, fertile soil. Harvest: July-October.
Tip: When transplanting cabbages to the garden, always firm them in well to prevent them becoming dislodged by strong winds.
