- Erect blackberries have stiff canes that are upright and arching. They can be trellised or grown in the landscape as a hedge or shrub border.
- Trailing blackberries have flexible canes that must be tied to a trellis so they don't flop to the ground.
- All blackberries grow best in full sun, and almost all varieties are self-fruitful, meaning that you need to plant only one cultivar. (Many other fruits are self-unfruitful, meaning you need to plant more than one variety in order for the plants to set fruit.)
- As a rule of thumb, five or six plants will produce enough berries for a family of four.
Varieties
Horticulturalists have been hybridizing blackberries for nearly a century and have developed a huge number of blackberries varieties. Different varieties grow best in different sections of the country, and it's important to select a variety that's well suited for your climate.
Note on the Cooperative Extension Services
You may have noticed that we often refer you to your local cooperative extension service for additional information. Why? Because extension service agents are local experts, the ones right in your own neighborhood. They understand your local climate and growing conditions better than anyone else.
