Kale - Bolshoi F1
Kale Bolshoi F1 is very winter-hardy, with a mild and sweet flavour. It is highly nutritious, and the leaves can be eaten raw or cooked as a good source of vitamins C and A.
Sow outdoors thinly from March to May, in a seed bed, 1.5cm 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 when seedlings are about 10cm tall, in rows 45cm apart. Plant firmly and water well. Or sow indoors, from March to May, 0.5cm deep, in a tray of compost. Water well and place in a cold frame or unheated greenhouse. Keep moist. Transplant 5cm apart to other trays, when large enough to handle. Gradually accustom young plants to outside conditions before planting out, during July/August, into well-cultivated, fertile soil. Harvest from September to March.
