How Do I Kill Wisteria?
Q: How do I kill wisteria?
A: Killing the main vine is not hard: simply sever it completely and everything beyond that point will die. The problem comes with killing all the little sprouts that will come up from the roots over the next couple of years. This job will take persistence. You can either take a weekly tour of the area and chop off any wisteria leaves you see or you can spray the new sprouts with herbicide. Either way, it will take at least two years to get mastery if the original wisteria vine was large and healthy.
