Description
'Superschmelz' Kohlrabi is an exceptional giant variety. It produces huge bulbs that weigh up to 10 kg. Unlike other giant varieties, its flesh remains tender and non-fibrous. Sow from March to July and harvest from June to November.
Kohlrabi, also known as Cabbage turnip or German turnip (Brassica oleracea gongylodes), is an original vegetable belonging to the large Brassicaceae family (ex-Cole family). This biennial plant, grown as an annual, is native to Europe where it was a staple food during World War II. It is recently being rediscovered thanks to its excellent flavour and great nutritional values. It is grown for its edible, bulbous stem which appears at ground level and measures between 6 and 20 cm in diameter. It is surrounded by a rosette of large green leaves.
This unusual vegetable has a fine, nutty flavour. It can be eaten both raw and cooked. It is delicious in salads, gratins or glazed with honey. The leaves are also edible and can be added to soups or stews. From a nutritional point of view, it is very healthy, being both low in calories and high in vitamins C and B3, fibre and minerals.
Kohlrabi is an easy vegetable to grow as long as you meet its basic requirements: deep, rich soil, and regular watering. It enjoys sun or half-shade.
Harvesting: Kohlrabi it is generally harvested from July to early November (75 days after sowing on average). Cut off the bulbs at ground level as and when required.
Storage: Kohlrabi can be stored for a fairly long time in a container of moist sand, in a cellar or basement. It will keep for several days in the refrigerator. It also freezes very well after being blanched for 5 minutes in boiling salted water.
Even if the vegetable garden is first and foremost a place for growing great quality veg, it’s always a good idea to leave a bit of room for flowers. Growing flowers alongside your vegetable plants will make your general gardening experience more enjoyable and is a great way to attract pollinators and repel garden pests! Flowers such as gaillardia, marigolds, zinnias, cosmos or nasturtiums can be sown in and around the rows of vegetables. Herbs such as dill can be very useful also. Bear in mind that some companion plants self-seed easily and can be a bit invasive (borage, chives, lemon balm etc.)

Planting and care
Sowing:
The germination temperature for Superschmelz Kohlrabi is between 7 and 30°C and takes between 8 and 10 days.
It can be sown from March to July for a harvest from June to November, when the bulbs reach 7 to 8 cm in diameter.
You can either directly sow the seeds in the designated spot or prepare seedlings that will later be transplanted to their final position in the garden.
Preparation of seedlings: In a nursery or garden, sow the seeds at a depth of 1.5 cm in a good seed compost. Lightly cover with compost or vermiculite. Remember to keep the substrate moist but not waterlogged!
When the young plants appear strong enough to handle, transplant them to their final position, respecting the recommended distances for direct sowing.
Direct sowing: In well-amended and finely worked soil, create furrows about one centimeter deep, spaced 30 cm apart. Sow the seeds every 3 cm and cover them with a thin layer of fine soil. When the seedlings are well developed, thin them out, leaving only one plant every 25 to 30 cm.
Hilling should be done when the bulbs start to form.
Cultivation:
Kohlrabi can be grown in full sun or partial shade. It is relatively easy to grow as it is less demanding than most cabbage varieties, but it still requires a good base fertilization and regular moisture. It is recommended to apply well-rotted compost (about 3 kg per m2) in autumn, by scratching it into the soil to a depth of 5 cm, after properly loosening the soil as you would for any vegetable crop. In acidic soil, it is important to gradually raise the pH by adding calcium in the form of Dolomite or Lime.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
