When to use the "cut stump" method of controlling invasive wisteria

Hello, I’m Amanda McNulty with Clemson Extension and Making It Grow. Clemson specialist David Coyle has blog post on wisteria. He refers to the invasive species ability to spread from treetop to treetop, in effect tying these trees all together and making them dangerous to harvest. He suggests that when you plan to use the "cut stump" method of killing these invasive vines, not to cut the vines in summer as they’re full of water and as they dry out they’ll shrink and can strangle the trees they’re wrapped around. There was a pine plantation I drove by that had a only a portion of it clear cut; I asked the forester why only that portion and he said they were losing twenty acres a year as wisteria had taken over that area. Plant our native species for beauty and as a larval food source.
