A leafy vegetable that forms a tight head. Cabbages can be green or purple and vary in size from heads only 15cm across to heads as large as 30cm in diameter.
Cabbage is grown in fields.
It can be seeded in a greenhouse for an early crop. The transplants are set out 30 to 50 days after seeding, when the plants are about 15cm high. Before setting out, the seedling is hardened off. This means stressing the young plant so it gets used to the harsher conditions in a field. Cabbage can be seeded directly into a seed bed when the weather is warm enough.
