@Dudie58, my neighbor works at a nursery. He has to adjoin the same vacant lot we do. We have been chopping and burning and smothering blackberry for two years, while he has them controlled. He used Crossbow and Roundup too. All neighbors except he and I, received critical letters from the city about controlling any black berry vines. Due to this, we will probably use the same solution if needed, so thank you for that post.
