Columnaris Tallhedge, Upright Glossy Buckthorn, Tallhedge
For use as a hedge, set plants 4 feet apart to allow for ultimate growth, or closer for rapid coverage. Before planting, prepare the soil well and deeply, adding organic matter. R. frangula is tolerant of a wide range of soil types. Full sun will provide maximum fruit production, but plants will also prosper in light shade. Mulch well after planting.
Though sides of plants should not need pruning, prune tops to obtain desired height. Such pruning is best done before growth starts in spring, and again during early summer as needed. Water liberally during hot, dry weather, especially in the first couple of years, as plants establish themselves.
