 | How To Kill Wisteria |
Glad you asked...
To kill a mature wisteria you will want to cut it off about one foot above the ground. Scrape back the bark on the remaining truck and apply a lawn herbicide. Be sure to mix it by package directions. This should kill the plant. More ideas and suggestions for getting rid of a wisteria plant can be found on this site. http://www.ubcbotanicalgarden.org/forums...
Then again, this answer might help you...
To kill wisteria before it takes over your homes or trees, start by pulling or digging up any young sprouts, cut the wisteria to the ground to avoid regrowth, finally use a specially formulated herbicide to get rid of the rest of the wisteria for good.
