Diseases & Pests: Slugs and snails – Sprinkle broken eggshells around plants to deter.
Cabbage aphids – A hard stream of water can be used to remove aphids from plants early in the day.
Cabbage root maggot – White maggot larvae feed on roots of plants. Damage causes wilting early on, and the death of plants later on.
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. Control weeds.
Cabbageworms – Hand-pick and destroy. Row covers may be useful on small plantings to help protect plants from early damage.
Companion Planting: All Brassicas benefit from chamomile, dill, mint, rosemary, and sage. Avoid planting near eggplants, peppers, potatoes, or tomatoes.
