how to get rid of black berry bushes
Hi, Well it's not going to be easy. You actually have two problems here--the blackberries AND a slope that goes down to a river. Generally, we recommend using a brush-b-gone type of herbicide on these plants, but you would never want to use that if there's any chance it could into the river. You might need to hire someone with a Bobcat endloader to excavate the site and remove them that way.
