Land contaminated with cabbage hernia is unsuitable for growing cabbage.
The growths on the roots caused by a slime mold prevent the development of the kohlrabi plants. Where such phenomena appear (the plants wither in the sunshine), the infested Ff lances with the roots and the soil surrounding them must be carefully removed and destroyed. No kohlrabi is allowed on this land for at least three years. Lime heavily in the meantime. Also about 3 Weeks before replanting, each m2 is approx 1 kg caustic lime spread and chopped.
