How to kill Wisteria- Steps to Follow
Step 1: Prepare the herbicide mixture using any of the 3 herbicides. Using a small disposable bowl, prepare 15 to 20% herbicide mixture. You can find premixed solutions ready to use in the market if you don’t prefer to mix it yourself but they cost more. You may also add some vegetable oil or diesel fuel to the solution to allow the mixture to penetrate into the wisteria more effectively.
Step 2: Using a handsaw gives wisteria stumps a nice horizontal cut. Leave a few inches protruding from the ground. If you had cut the wisteria to a stump before, cut the stump again to provide a fresh cut for treating with herbicide. The herbicide works best on a fresh cut no more than 4 hours after cutting. The deeper the cut, the better the herbicide will penetrate.
Step 3: peel the back around the stump nicely. Peel the bark to about 1 inch down the stump to provide an open surface for herbicide penetration. Use a small pocket knife it works better and faster.
Step 4: Using the paintbrush, paint the upper part of the stump with your well-mixed herbicide. Apply a lot of herbicide but be careful not to have it dripping on other plants. Leave it for an entire day to allow the herbicide to seep through the very interior of the stump and its roots.
Step 5: After 24 hours, repeat the application process again and give it between 1 to 4 weeks. This will depend on the size of the wisteria.
Step 6: After ample time for the wisteria to completely die, cut the stump off. Make sure the roots have died too and pull them out. This ensures that it doesn’t grow again.
Wisteria though a nice ornamental plant will at times become a hassle to maintain. Rescue your yard by destroying it as soon as you realize it’s getting out of hand!
