Description

Red cabbage is also known as red cabbage or blue cabbage. It originates from the Mediterranean region and has evolved from a wild form of vegetable cabbage. Red cabbage is a classic winter vegetable and has many similarities to white cabbage, so it also belongs to the cruciferous family (Brassicaceae), but grows more slowly and forms smaller, purple heads. The shape can be round, pointed or oval. The biennial plant is usually harvested in the first year, so its flowers are rarely seen. The leaves of cabbage grow densely and take on a different color from blue to purple depending on the pH, so it also serves as an indicator of the pH of the soil in which it is grown. There is also a distinction between early, mid-late and late red cabbage depending on the variety. Early red cabbage prefers sandy soils, medium-late and late rather loamy soils.

Growing tips

Red cabbage is a heavy feeder and therefore requires a well-fertilized, lime-rich soil and fertilization during the head formation period. Plant manure, rock flour and compost are therefore well suited. Organic components are particularly important. However, you should not over-fertilize, as this will affect the taste. Late varieties should also not be fertilized from September onwards. The location can be sunny or partially shaded. Important for cabbage varieties: Only grow on the same bed every 3-4 years to avoid diseases and pests. Red cabbage can be sown directly or grown in advance. The period depends on the variety, with early varieties, cultivation begins as early as February. Leave at least 50 cm between the plants, otherwise the heads will remain very small and promote disease development. If planting before May, it may be useful to protect the cabbage with a fleece during cold nights. The soil should always be moist. Weeds should be removed regularly. The growing period is approx. 14-21 weeks. For longer storage, take the stalk out of the soil and hang it upside down in a cool, damp place.
