Paul from Oregon City, Or writes

Will Crossbow kill invasive Catalpa trees? If so what is the best method?

We cut the trees to ground level, sprayed the cut stump, put holes in the center and poured Crossbow in and 6 months later, around each stump, we have the roots at the base of the stump and creating sprouts up to 20 or 30 feet away.


Helena Crossbow Herbicide does not specifically list Catalpa on the label as a controlled tree.  We would recommend checking directly with Dow to confirm if it is effective for your target tree. You can reach Dow at 800-992-5994.
