Clubroot is not the newest bar in town; it is a disease of many fall and winter crops. Clubroot, or club root, is caused by an imported plant parasite that grows inside of plant cells. This parasite used to be classified as a slime mold, but is now in an entirely different category, called Phytomyxea. This pathogen is called Plasmodiophora brassicae, but don’t let the name scare you off from learning about it. The brassicae part of the name tells you which plants are susceptible: members of the cabbage family. The Plasmodiophora part of the name tells us that these are mouthless, amoeba-like plant parasites. Which plants are affected by clubroot? Clubroot occurs in nearly all members of the brassica family. This means that your broccoli, Brussels sprouts, cabbages, cauliflower, radishes, and turnips are susceptible. In addition, alyssum, mustard, nasturtium, and wallflowers, as brassicas, can also become infested with this parasite. Symptoms of clubroot

Soil solarization is the only sure way to get rid of it, and that only works if the solarization is done properly. Use these tips to reduce the chance of clubroot occurring in your garden:
