Woody Weeds: Common Buckthorn

When considering weed control in tree plantings, the focus is generally placed on the control of herbaceous vegetation (grasses and forbs), particularly during the establishment phase. This focus is appropriate since control of herbaceous weeds is generally critical to establish a successful planting. As these plantings mature, providing perching sites for birds, another weed problem develops – the establishment of competing woody vegetation. These woody weeds are often left unchecked for many years because they look “natural” in a windbreak or other area of trees.
