Best types of winter cabbage for UK gardens
Savoy cabbage varieties such as Winter King, Tundra, and Savoy King are excellent choices for cold months as they sweeten after frost. January King remains a favourite for traditional allotments with its tough leaves and attractive colour. Red cabbage like Red Drumhead and Red Russian bring vibrant shades to winter meals and keep well in store. Dutch winter cabbages are firm and bred for late harvest, giving growers reliable results.
When to plant winter cabbage in the UK
Seeds can be sown indoors during April and May, either in trays or modules to start them off strongly. Once the seedlings reach four to six true leaves, they can be transplanted outdoors from late May through July. Winter cabbage is usually ready to harvest between October and March, providing a steady crop during the colder months.
Do winter cabbages survive frosts?
Most winter cabbages are naturally frost hardy and even improve in flavour after cold weather. Savoy and January King varieties are particularly reliable during harsh winters. While they cope with frost, you may choose to add fleece in very severe conditions to stop frost heave and keep the plants stable.
Covering in butterfly netting for protection
Although winter sowings face fewer pests, cabbage white butterflies may still appear in early autumn. Covering in butterfly netting helps prevent eggs being laid on leaves. Cabbage collars are also useful to protect stems from root fly attack and ensure plants establish strongly before winter sets in.
When will the cabbages be ready to eat
Harvesting times depend on the variety, but many winter cabbages can be cut from late October. Some remain firm in the ground until February or March. Pick the outer leaves first if you prefer a steady supply, or cut the whole head once it reaches a firm size. Stored red cabbages can last even longer in a cool, dark place.
