Blackberries and raspberries are closely related and have similar growing requirements, but blackberries are larger and more vigorous, and some varieties are less hardy. Blackberries come in two fairly distinct forms—erect and trailing—and have a number of different names.

The ordinary blackberry is a stiff-caned, fairly hardy plant that can stand by itself if properly pruned. The trailing kind, generally called dewberries, are tender and grown mainly in the South. Trailing plants from the Pacific Coast are sold under their variety names—for example, 'Boysen' and 'Logan'—and are not referred to as dewberries. These varieties will freeze in the East and the North without winter protection.

Blackberries like a light, well-drained soil with a high moisture-holding capacity. Do not plant them where tomatoes, potatoes, or eggplants have grown previously, since the site may be infected with verticillium wilt and the berries cannot grow there.

Plant in early spring a month before the last frost. Set plants 4 to 6 feet apart in rows 6 to 9 feet apart. Before planting, clip canes to 6-inch stubs and plant at the depth they grew in the nursery. As soon as new growth begins, cut any stubs that do not sprout and burn them to protect plants from anthracnose, a fungal leaf-spot disease that can infect bramble plants. It is a problem in moist, warm climates, especially in the South.

Several inches of mulch will help keep soil moist, prevent weed growth, and help prevent suckers. Mulches such as fresh straw or sawdust use up nitrogen in the soil and you must supply extra nitrogen, but in general, don't fertilize too heavily or you'll get lush plant growth at the expense of a fruit crop.

The stiff-caned berries need no support, but can be confined between two wires to save space. Trailing blackberries should be cut to the ground after fruiting and the clippings destroyed to reduce the chances of spreading disease. New growth that sprouts during the last part of summer will fruit the following year.

If you disturb or cut roots of blackberries they will sucker badly. If you want more plants, chop off pieces of root beside the parent plants and set them in the new planting site like seed. If you don't want more plants, mulch the planting instead of cultivating for weed control. Blackberries can be more invasive than any other cultivated plant and, if abandoned, can quickly grow out of control.

Blackberries are subject to many pests and diseases. Save yourself trouble by buying certified plants and keeping them away from any wild plants. Some varieties resist a few diseases. Spray for blackberry mite and don't worry too much about the rest.

Either dewberries or erect blackberries can be planted in much of the South. In colder parts of the South, choose only the erect blackberry or be prepared to offer winter protection by burying canes under 2 inches of soil after the first frost, and then digging them out just as buds begin to swell.
