White cabbage Brunswijker - cabbage seeds

Brassica oleracea convar. capitata - Brunswijker

A biennial plant that forms heads in the first year, covered with blistered, lobed leaves of yellow-green to dark green color. It grows on a short stem. In the second year, a flower spike with four-petaled flowers grows through the head. The most well-known cabbage varieties include head cabbage, kale, and Brussels sprouts.

Cabbage is rich in vitamin C, K, and minerals. It contains many vitamins (such as B1, B2, B3, B9, C, and K). It is rich in minerals and trace elements (magnesium, selenium, potassium, calcium, phosphorus, and iron). It is used in soups, sauces, or vegetable salads.

How to Grow Cabbage

• Head cabbage grows best at a constant temperature ranging between 15–20 degrees Celsius. Do not plant them too close together. This has a negative impact on yield! The plants are frost-resistant. They tolerate temperatures from -10 to -15°C without problems. They require sunny or partially shaded locations. At the beginning of summer, plants require large amounts of water. The soil should never dry out. Regularly hoe around the plants and remove weeds. Also regularly lime and fertilize.

• Early varieties are sown in February in a warm greenhouse or hotbed. Planting is carried out in April at a spacing of 40×50 cm.

  Summer and semi-early varieties are sown from mid-April to May directly on site at a spacing of 50×40 cm.

  Autumn varieties are planted until the end of July directly on site at a spacing of 40–50×60 cm.

  Winter varieties are planted at a spacing of 40×40 cm until the end of September.

• Late varieties require medium-heavy soils with sufficient calcium content. Varieties intended for field cultivation and cold forcing require lighter, sandy-loam and warming soil. The optimal pH value is 6-7.

• In autumn, it is advisable to work 4–5 kg of farmyard manure/m2, 5g P2O5/m2, 10–14 g K2O/m2 into the soil. Don't forget to lime the soil. Apply another dose of 8–10 g nitrogen/m2 before planting. During the growing season, add another 2–5 g nitrogen/m2, evenly distributed for application at the 8–9 leaf stage and before head formation.

• The most common cabbage pests are cabbage flea beetle, cabbage white butterfly, and cabbage moth. Among diseases, clubroot of brassicas causes the most damage.

  For cabbage moth, it is advisable to use synthetic insecticides or preparations based on 'Bacillus thuringiensis' during the hatching of caterpillars from eggs.

  Against clubroot of brassicas, liming of land, use of nitrogen lime, destruction of affected plants, and soil disinfection are recommended.

  Plants can be protected from white butterflies by planting them among tomatoes, for example.

• Early varieties are harvested in May or June. The growing period until harvest ranges from 50-70 days.

  Summer and semi-early varieties have a growing period of approximately 120 days. Harvesting is therefore carried out in August to September.

  Autumn varieties have a growing period of 102–160 days. Harvesting is carried out in August to September.

  Winter varieties have a growing period of 240–250 days. They can be harvested until January.
