Common names: Blue cabbage, Red cabbage

This description was machine-translated.

Description

The plant forms firm, blue‑violet heads and is a classic winter vegetable in autumn and winter. Whether it looks more like red cabbage or blue cabbage depends on the soil—acidic soil makes it appear redder, while calcareous soil gives it a bluer hue.

Care instructions

Start seedlings in March or purchase transplants and plant them about one arm’s length apart in a nutrient‑rich, firm bed. Keep the soil evenly moist, give one feeding during the season, and protect young plants with a net against cabbage white and soil flea beetles. Harvest from August to November.
