The name is a little misleading as December is the end of the harvest period which starts in October. Large heads of blue-green outer leaves and crisp hearts.
WHEN TO SOW
April and May.
WHERE TO SOW
Sow the seed thinly in a well prepared seed bed in shallow drills 2cm deep. Keep well watered.
WHAT TO DO NEXT
Thin the seedlings as they appear to 5cm apart. When the seedlings are about 10-15cm tall, transplant to the growing site 45-50cm apart. Set the young plants 2cm deeper than they were in the seed bed.
September to November.
Cabbages are hungry plants. Rake a general fertiliser into the topsoil a week before planting out. When planting, tread the plants in firmly.
