Common Pests & Diseases
Diseases
May be susceptible to brassica downy mildew and brassica white blister. In areas where brassicas have been grown before, clubroot can build up in the soil
Pests
May be susceptible to flea beetle which can prevent seedlings from thriving and attacked by caterpillars when eggs laid by butterflies, hatch and feed. It is very popular food for pigeons which only netting can prevent. It is also eaten by snails, although once plants are established, this damage isn't usually severe. The cabbage root fly can cause failure to thrive and a heavy infestation of mealy cabbage aphid can spoil the harvest
