How do I kill blackberry bushes?

Question

My son bought this house with a long driveway……and there is a HUGE blackberry bush………50 feet long, 10 feet wide and 6 feet tall. I have cut out 99% but there is new growth daily. HELP!

Answer 1

You will have to keep all new growth cut as often as possible. Pour boiling water on all parts of the plant and the area surrounding it. This will usually do most of the work. If these manual methods don't work, you will have to turn to chemical herbicides, such as a brush killer.
