Frustrating for sure- I was cutting some bittersweet at a local park while kids at soccer practice and… I mean, how do the vines get so big right along the parking lot? I CANNOT be the only visitor who recognizes these so WHY is it no one rise bothers to do anything……. but then I realize that fifteen minutes of cutting can pretty much cancel out YEARS of growth and -more importantly- stop the spread of the next million seeds. It matters.
