Buckthorn growing in the clump of evergreens on the northeast side of the yard. I've removed a lot of it all over the yard during the past few years. My goal this year was to finally get rid of any buckthorn that has berries on it. The remainder will be dealt with next year and then I'll finally reach my goal of a buckthorn-free yard! If you're not familiar of buckthorn see this article on Buckthorn: Invasive species by the Minnesota DNR.
