In eastern N.C., when planting cabbage behind potatoes, the base fertilizer application may be reduced. If boron is not added to the fertilizer, spray 10 lb of Solubor or 2 quarts of N-Boron per acre directed to the base of the plant. Cabbage plants need this as they begin growing. Apply another nitrogen sidedressing 3 weeks later. Cabbage has a high nitrogen requirement early in its growth.
Cabbage is a shallow rooted crop.
Chemicals for weed control are available and generally perform very satisfactorily. Do not depend solely on postemergence materials. Because of the complexity of the problem, it is suggested that growers work closely with their local cooperative extension agent in selection of materials and methods of application. A control program must be started early. This is especially true for the cabbage looper and other worms.
