Overwintering cabbages is a method whereby spring cabbages are late summer sown. by doing this they produce small tender cabbages or spring greens in April and May. Confusingly, late spring sowing of Durham Elf can ensure earlier crops in autumn and winter so I may try those next Spring..
To over winter cabbages sow mid July to August ¼” deep in a seed bed or in trays of seed compost. Keep moist. Transplant to their final position when plants can be easily handled which should be in about 5-6 weeks.
Allow 18” between plants. Plant firmly and water well until established. Harvest in April and May for good firm hearts.
The four varieties that I am sowing today are Durham Early, Durham Elf, First Early Market and Offenham 2 Flower of Spring.
Update – The seeds I sowed on 13th August have not all germinated. Today 4th September I have potted on 12 First Early Market. Nothing else was big enough to transplant but I shall leave them a little longer.
I am hoping to get these in at the allotment in the middle of October and hope to harvest in April and May 2019. They will be protected by a tunnel as we have lots of hungry pigeons down there..
