How to Kill a Yew Tree
- 1). Cut the yet tree down to a stump and make sure that the top surface is level. This will lead to a uniform coverage of herbicide and will minimize runoff. Recommended herbicides include products containing dicamba, glyphosate and imazapyr.
- 2). Apply the herbicide immediately to the fresh wood to maximize efficacy of the chemical. If you are not able to treat the stump right away, cut the top surface again to expose fresh wood at the time of herbicide application.
- 3). Saturate the outermost 2 to 3 inches of the stump right next to the bark. This is the cambial layer that will conduct the chemical to the roots. The center wood of trees with a trunk diameter of over 3 inches is dead heartwood and does not require chemical application.
- 4). Cover the entire stump surface with herbicide if the yew tree is 3 inches or less in diameter.
