Diseases and pests

It is not very sensitive. If attacked, use the same methods as with cabbage.

Kohlrabi’s storage

Pick the swollen stems when they reach approx. 5 cm (2 in) thick, or earlier in summer, as they lignify later. Store them in plastic bags up to three weeks in the fridge. They last up to three months in a moist and cool basement.

Food

Use young, meaty swollen stem and leaves (like leafy greens, for juices and in different dishes). It contains the majority of vitamins and minerals.

Important

It doesn’t grow well in acidic soil. If it lacks moisture, the tubers burst.

Miscellaneous

It is also called German turnip or turnip cabbage, because its swollen stem resembles a turnip, but it shouldn’t be confused with rutabaga (Swedish/yellow turnip). There are white and red varieties. The red ones are less sensitive and contain some more beneficial substances.
