With more extended ripening, the vegetables often become woody. The plants are getting cut off with garden shears just below the tuber for harvesting.

Growing kohlrabi on the balcony

If you don’t enjoy or have access to a garden but have a beautiful and sunny balcony, don’t despair. Kohlrabi cultivation is also thriving there. 

However, the mandatory minimum distance of 25 cm between the individual kohlrabi plants is a limiting factor. Usually, the plant pots are only large enough to accommodate a kohlrabi plant. 

A homemade raised bed can be an alternative to plant pots.
