Cabbage is considered a cool-season vegetable. Cool-season vegetables can withstand temperatures below 32 F (how far below varies by crop and situation) and are generally more productive and have higher quality produce when grown during cooler spring and fall seasons.
Cabbage is typically grown in the garden using transplants and can be successfully planted in the garden in mid-March through mid-April for spring planting and mid-August for fall planting. A spacing of 1 - 2 feet between plants is ideal.
Recommended cultivars include Caraflex, Katarina, Dynamo, Famosa, and Blue Vantage.

A range of immature moths feed on the foliage leaving moderate to large holes in the leaves. Netting or row covers can exclude these pests, and biological or conventional insecticides can be used for control.
Clubroot is a major disease of cool season crops and causes roots to enlarge to form galls that look like spindle-shaped swelled roots. Infected roots cannot absorb water or nutrients, so the plant becomes wilted and leaves may turn yellow and drop off.
Downy Mildew looks like purplish spots that then turn yellow/brown on the upper side of the leaf. You may see the growth on the leaf underside. Protective fungicides, crop rotation, and resistant cultivars can be useful.
