More about this problem

What you will see

Thickened and distorted roots; plants lag behind and wilt.

The source says: in brassicas it causes swollen roots and severely stunted growth.

When to look

Midsummer to late autumn

How to protect

  1. Prevention
    • Buy plants only from a source guaranteed free of clubroot; be careful even with plants from friends.
    • Do not carry soil on tools, wheelbarrows and footwear.
    • On acid soil, lime (500 g/m², then 270 g/m² in following years) and improve drainage; this reduces the disease but does not rule it out.
    • Grow young plants on for longer in healthy soil (pots at least 9 cm) and plant them out larger; consider varieties with partial resistance.
  2. By hand as soon as it appearsDig up affected plants, roots included, and dispose of them (do not compost). There is no chemical product for gardeners against clubroot.
