A white cabbage plant of almost 3 kg in the midst of winter. This cultivar of cabbage can withstand several nights of freezing temperatures.

Preventing clubroot

Today i planted white cabbage plants. They were pre-sown in the greenhouse. Cabbage can suffer from infections by a single-celled organism called Plasmodiophora.[1] The disease is called clubroot[2] and can affect species of the mustard family, Cruciferae, such as cabbages, radishes and turnips. Clubroot causes tumors in the roots and can block growth of the plant and even cause death. Clubroot can easily be prevented by adding a handful of agricultural lime to the planting hole. I always dig a hole some 50 cm deep and fill that with a half a bucket of compost, a handful of lime, a handful of bentonite and a handful of lava dust. The organism that causes clubfoot doesn't like lime, but cabbages do. Originally cabbages come from a wild species that grows at beaches near seas and oceans.
