The seed is sown as for summer and autumn cabbages; in the north, it may be necessary to sow it in the middle of March, but in areas where the weather is mild it can be sown in April or May. To save time the seeds can be sown where they are to grow. Sow three seeds every 2 ft (60cm) along a drill; later the plants can be thinned out to allow room for good growth and development. Those that were not sown in their final growing position can be planted out in July allowing 2 ft. (60cm) between the plants.
Winter cabbage will be ready for cutting any time between November and the end of February depending of course on the variety sown. It will be a long time before the hearts burst and run to seed once the cold weather has arrived.
