Kohlrabi were probably first cultivated in Italy, we know the related with sea cabbage tubers only 400 years. Nevertheless, they are considered typical German vegetables - even in England and Japan they are called Kohlrabi. Early varieties are ready for harvest in April. However, those who stagger the cultivation and choose the right varieties can harvest almost all year round.
Plant early kohlrabi varieties under fleece or foil
It starts with 'Azur Star'. Because of its deep blue color, the traditional kohlrabi breeding is one of the most beautiful and at the same time the tastiest varieties for growing in the cold frame or outdoor under fleece and foil. Also 'Lanro' with round, light green tubers can already be sown from February and planted from the beginning of March under fleece or foil into the open. Last cultivation date is in September. 'Rasko' is a recommendation for raw food fans. The newer, seed-proof organic variety convinces with its nutty-sweet aroma and buttery, creamy-white flesh. Varieties for the autumn harvest like 'Superschmelz' or 'Kossak' give you time to grow. But the tubers are almost as big as cabbages and still remain juicy.
To prefer sowing from February in pot plates with 4 to 5 centimeters large pots. Ideal germination temperature: 15 to 18 degrees Celsius. If the seedlings have 3 to 4 leaves developed, is planted out. Larger plants grow worse
Without winter protection, you can plant kohlrabi in mild locations from the end of March. Seedlings that have just formed three to four leaves, can cope with the move to the bed without problems. Larger young plants are often too long in the pot and grow worse. Make sure the stem approach is barely covered with soil. Too low kohlrabi make no or only thin, elongated tubers. The distance in the row is 25 centimeters for small-seeded cultivars, the row spacing is 30 centimeters. Large-sized kohlrabi like the 'Superschmelz' need 50 x 60 centimeters of space.
"Vollholz Kohlrabi" only has to fear who forgets the casting. Even if the planting distance is too narrow, the soil is crusted or the weeds become soiled, the kohlrabi tubers only grow slowly and form hard fibers around the roots. A far planting distance and low-dose, but more frequent fertilizer from the beginning of tuber development are more favorable than a high single dose. If the plants are too warm, tuber formation is also delayed. Therefore, ventilate vigorously in the cold frame, the greenhouse and the film tunnel as soon as the temperatures rise above 20 degrees Celsius.
Make young heart leaves like spinach
Harvest early kohlrabi varieties before the tubers reach their typical size. In doing so, do not cut off the stalk, but pull out with it, in order to prevent carbon-hernia infestation
Rapidly growing early varieties develop more foliage than the later varieties. Especially young heart leaves are too good to throw away, because they provide plenty of beta-carotene and phytochemicals. You sprinkle them raw and cut into thin strips over soup and salad or prepare them like spinach. The tubers also come up with healthy ingredients: Noteworthy is the high proportion of vitamin C as well as B vitamins for good nerves and zinc, the all-rounder among the minerals. Another reason for the separate use of leaf and tuber: Without the anyway fast-withering green Kohlrabi evaporate less water and stay fresh and crisp in the refrigerator for a week. Late varieties - such as carrots and other root vegetables - can be stored in the humid cellar for a good two months.
Tip: Plant kohlrabi as a mixed culture
With the right partners, kohlrabi thrive better - so you should plant them together with other vegetable garden as a mixed crop. Our bedding proposal has several advantages that benefit all participating plants: Lettuce distributes ground fleas, while spinach promotes the growth of all types of vegetables through its root excretions (saponins). Beetroot and kohlrabi are rooted at different depths and make optimal use of nutrients stored in the soil. Fennel and herbs fight off pests.
In the field, one sows in rows (distance 30 centimeters) and warps the seedlings later on 25 to 30 centimeters in the row. Be patient with the sowing! If temperatures fall below 10 degrees Celsius during the germination phase, kohlrabi do not shoot or shoot
Row 1: blue early kohlrabi and lettuce, for example the variety 'Maikönig'
Series 2 and 6: Sow the spinach and harvest it as a baby leaf salad once the leaves are hand-grown
Row 3: Planting or sowing early white kohlrabi and beetroot
Row 4: quickly growing spring herbs such as parsley and cutlets
Row 5: Put tuber fennel and blue early kohlrabi
Row 7: Plant late-kohlrabi and pickle salad
