I will cut and dab the end. But I have trees next to them and don't want to harm them.
The Bonide Stump Out & Vine Killer will work on the cut stumps of blackberry bushes when used as directed on the product label. You would apply this product undiluted to kill stumps and prevent sprouting. Using the application top, completely cover the freshly cut surface. Be sure you do not apply when temperatures are over about 85 degrees to help reduce risk to nearby plants.
