Growing Blackberries: Trailing and Erect Varieties
If you plan to grow blackberries, it's important to understand that there are two varieties: erect and trailing.
Comparing Erect and Trailing Blackberries
The main difference between the two is how the canes grow. Erect blackberries have a stiff, arching stem that is good at supporting the plant. Trailing blackberries have stems that are not self-supporting. Some varieties include Marionberry, Boysenberry, Loganberry, Youngberry, and Thornless Evergreen.
Erect blackberries stand the cold better than the trailing variety. But it is possible to grow trailing blackberries in colder areas if you leave the stems on the ground and mulch the plants in the winter.
Whatever varieties you choose to plant, it's important to select a sunny area in your garden that has good air circulation and water drainage. The pH of the soil should be between 6 and 7. The roots should be moist until you plant them in the ground. Also, it's a good idea to place of a lot of organic matter in the soil and mulch so that weeds don't grow. Once the soil has become warm enough, you should plant the blackberries. Simply dig a hole that will allow the roots to sit in the ground without being damaged. To encourage new growth, trim the stems. Place the plants in the ground about 2 feet apart in rows 7 feet apart. If you want to support the stems, use trellising.
