Fresh kohlrabi from your own garden are a treat. Cultivation begins with sowing directly into the bed or growing in pots or trays. Seeds for white or blue kohlrabi varieties are available from garden centers or online. Depending on the variety, one bag contains seeds for 80 to 100 plants.
Direct sowing in the bed
You can sow kohlrabi directly into the vegetable patch from the end of March to mid-June. Early varieties such as "Lanro", which are not sensitive to cold, are the first.
Kohlrabi thrive in medium-heavy, nutrient-rich soil in a sunny, not too dry location. To enrich the nutrients, compost is dug into the bed as early as autumn.
The kohlrabi seed is sown thinly in 0.5 to 1 cm deep grooves and only lightly covered with soil. At temperatures above 16 °C, the seed will germinate after about a week.
Once the seed has sprouted, you need to prick out the young plants regularly. Only then will the tubers have enough space to develop magnificently. A distance of at least 15 cm between the kohlrabi plants and approx. 30 cm between the rows is ideal.
prefer kohlrabi
Starting in February, growing the kohlrabi plants on the bright, warm window sill is quite easy. You need:
- seed pots or
- bowls or
- clean yoghurt cups and
- potting soil
The seed is sown thinly in the vessels, lightly covered with soil and kept moist. If the cultivation temperature is between 12 - 15 °C, the first peaks appear after a week.
If all the seeds develop, you have to prick them out here too. The young plants can move to the garden bed when they have developed 3 - 4 leaves.
