Physical: Small trees can be cut down at ground level. With large trees, it may be easier to make an incision that encircles the base of the tree well below the bark, six inches from the ground. Resprouts are common, so cutting is only an initial control measure and should be followed by chemical controls or repeated cutting. Hand pulling can be effective on young seedlings, and they should be pulled as soon as they are large enough to grasp but before they are old enough to flower. The entire root should be removed to prevent broken fragments from resprouting.
Chemical: Chemical controls include glyphosate (Roundup) and triclopyr (Garlon). Glyphosate is a non-selective herbicide that may kill partially contacted, non-target plants, so it should be used with care. In areas where native or other desirable grasses must be conserved, triclopyr should be considered. Triclopyr is a selective herbicide for many broad-leaved plant species.
