Pests and Diseases
Aphids – spraying your brassicas with diluted washing up liquid will deter them from landing on your crops. You can buy insecticides if you prefer, including a fatty acid soap to spray on the plants.
Carrot fly – a particular problem between May and September when female flies lay their eggs the best defence to cover plants with horticultural fleece or place two-foot-high barriers around the plants.
Cabbage root fly– attacking the roots of brassicas, these flies can cause a lot of damage to your plants. Female flies lay the eggs on the surface of the soil next to the stem of the plant. Place a piece of carpet (or cardboard or fleece) around the base of the plant to create a collar, this will stop the flies from laying their eggs on the soil.
