Blackberries are something of an ugly duckling compared with other berries. The large, dark-colored berries are not as popular as strawberries, raspberries and blueberries in cooking and baking, but they can still be a worthwhile addition to your home garden.
Blackberries grow on bushes. There are three types: trailing, which require support from a trellis, and erect and semi-erect, which are self-supporting.
Blackberry bushes should be planted in the early spring, as soon as the soil is warm enough to work with, according to the Oregon State University Extension Service. Keep in mind that the bushes should not produce fruit in the first year. After two or three years, though, you should get a good crop of berries each summer.
Choose a spot for planting your blackberry bushes. Plants prefer full sun, but can tolerate partial shade. Plants also need a well-draining soil because they can be damaged by wet or saturated soil.
Remove weeds, rocks, sticks and other debris from the planting site. You can pull weeds by hand or apply an herbicide if there are a lot of weeds.
Dig a hole large enough to accommodate the blackberry bush's root structure. Blackberry bushes should be planted at the same depth they were grown at the nursery. A soil line on the plant should indicate the depth at which it should be planted.
Place the plant in the hole, setting it down firmly, but gently in the soil. Allow the roots to spread out naturally so they are not bent or damaged in the planting process.
Fill in the hole with the surrounding soil, using your hands or feet to pack it down firmly to remove any air bubbles.
Water the bush immediately after planting to settle the soil and allow it to begin establishing its roots. Blackberry bushes need about 1 inch of water per week, so be sure to water them regularly during dry spells.
Prune the canes of the bush back to 6 inches in length if they have not been cut back by the nursery.
