Blackberries are a powerhouse of nutrition. According to the Oregon Raspberry and Blackberry Commission, blackberries are astonishingly high in antioxidants as well as anthocyanins. They are easily grown but can easily take over an area if they are not taken care of, as they are fast-growing!
Prune your blackberry bush canes at least once every summer after they have finished fruiting. These brambles will grow leafy canes every spring that don’t produce fruit until the following year, so don’t cut them off. Instead, look for the canes that have finished fruiting, and cut them back to the ground. You should be able to recognize them by their brown bark compared to the green bark of the new canes.
