Managing buckhorn is a perennial project. Persistence is key as plants from seeds will be a continual issue, dropped by birds and other wildlife. There are several methods used to manage buckthorn depending on location, stage of growth, and time of year. Below, I am giving you extension articles that describe management options.
The baggie technique is used on cut stumps and is relatively new. Non-chemical control options for cut stumps include covering the cut stump with a tin can or durable black plastic (such as a "Buckthorn Baggie") to prevent re-sprouting. After cutting the tree, apply the can or plastic over the cut stump and root flare. Use nails to affix the can or a tie to affix the black plastic. Leave in place for one to two years.
If you have more questions, please write again. Thank you and good luck with your project.
