How can I control my Clubroot naturally?
Carefully remove infected plants and sterilize garden tools (one part bleach to 4 parts water) after use. Raise your soil's pH to a more alkaline 7.2 by mixing oyster shell or dolomite lime into your garden in the fall. Simple and affordable soil test kits are available to check pH often.
How do you prevent clubroot in brassicas?
Make the Soil Unattractive to Clubroot

How do you test for clubroot?
Random soil tests can pick up clubroot DNA before you see visual symptoms. Labs that test soil for clubroot DNA are listed here. These labs can detect spores at levels of 1,000 per gram, which is considered fairly low risk for the development of galls.
How long does Clubroot stay in the soil?
How does clubroot affect crops? The soilborne pathogen that causes clubroot (Plasmodiophora brassicae) survives for up to 15 years in the soil.
How do you control Plasmodiophora Brassicae?
NON-CHEMICAL CONTROL
brassicae infestation including buying or using disease free transplants, using well drained and pathogen free soil, eliminating nearby crucifer weeds, incorporating a 7-year rotation of non-cruciferous crops, adjusting soil pH to 7.2 or higher, and using resistant crop varieties.
What is cabbage club root?

How do you protect brassicas from cabbage root fly?
Plants can be protected by growing them under the cover of an insect-proof mesh. Horticultural fleece may be preferred for seedbeds as it will also help warm the soil. This can also help reduce other brassica problems such as cabbage caterpillars.
Do radishes get Clubroot?
