Diseases & Pests
Flea beetles – Use row covers to help protect plants from early damage. Put in place at planting and remove before temperatures get too hot in midsummer.
Cabbage root maggot – White maggots (larvae) attack all plants of the cabbage family. Larvae tunnel in and feed on roots of plants. Damage causes wilting early on, death of plants a little later on.
Cabbage aphids – A hard stream of water can be used to remove aphids from plants. Wash off with water occasionally as needed early in the day.
Cabbageworms – Handpick and destroy.
To help reduce disease, do not plant broccoli or other Brassicas in the same location more than once every three or four years.
