Use of Herbicides Around Your Trees    (View PDF)

John A. Meade

Abstract: Trees and herbicides (weed killers) can co-exist in harmony but occasionally injury occurs. The broadleaf lawn weed killers or brush controls are sometimes at fault but more often it is the total vegetation material which moves from the site (or tree roots grow into the site) and hence are absorbed. Once in the tree, little can be done to stop the action. Best advice is don't fertilize or water. These encourage the tree to make new growth and that's where the herbicide is acting. On the good side, herbicides can safely be used to trim the base of trees thus allowing a 6-8" band of vegetation free area around the base to keep the mowers away.
