Sure it's nice to have a few ornamental plants in your garden or lawn. But there are times these ornamental plants seem to become more of a hassle to us. One example of this is Wisteria. When they grow bigger, they become harder to maintain, and they just become a total mess when you forget to tend them for just a few days. It's because of this that we came to the rescue to help you out in teaching you how to kill wisteria for good.
What You Need To Prepare
The first and most important thing you need to have is the herbicide. This is the one which will kill the wisteria due to its chemical elements and properties. Triclopyr, glyphosate, and garlon, are some of the best pesticides you can use. These are very effective in killing off wisteria.
- KILLS WEEDS AND GRASSES: Use on driveways and walkways, and around fences, trees, flower beds, shrubs and other areas in your yard
- FAST-ACTING FORMULA: Visible results as fast as 3 hours – replant new flowers, trees and shrubs the same weekend
- RAINFAST: Rainfall or watering 15 minutes after application will not wash away effectiveness
- CONCENTRATE: Mix and apply with a tank sprayer – spray to completely cover the leaves of the target vegetation
2. Diesel Fuel or Vegetable Oil
Diesel and vegetable oil is also important to have. You’re going to mix this with the solution so that it can easily penetrate to the wisteria’s interior. It makes the herbicide stickier and more fluid, making it more capable of seeping through every inch of the wisteria.
3. Saw and Pocketknife
Prepare a saw and a pocket knife. You're going to use the saw to cut through the wisteria body. On the other hand, the pocket knife will be used to cut and slice through the wisteria, as well as peeling off its stump. You want its interior to be exposed and giving it cuts and peeling it off just does that.
However, it would be better if you'll be getting a saw and pocket knife that is not too big. You don't need a big one because wisterias aren’t that hard to cut as their branches are a bit soft and thin.
You're going to need a paintbrush because it's this that you'll use to apply the herbicide to the cuts and slices in the wisteria's body. Any paintbrush will do. However, it's best if you use one that is specifically designed for herbicide application. There are some herbicide packages that include its paintbrush. In choosing an herbicide product, it would be wise of you to choose one that has a paintbrush included.

The Step-by-Step Process
Step #1 Prepare the Mixture
The first thing you need to do is to prepare the mixture solution that you’re going to apply to the wisteria later on. You can use a disposable bowl as a container for the solution. However, it’s best if you have a garden hose sprayer.
The herbicide you’ll put inside it can be triclopyr, glyphosate, or garlon. There are pre-mixed solutions you can find on the market. These are the ones recommended because you don't have to worry about doing mixings and stuff.
Just remember that they’re more expensive than the one you still need to mix. It’s also recommended that you add a bit of diesel fuel or vegetable oil to the solution so that it can penetrate the wisteria better.
Step #2 Make a Cut
The next thing you’ll do is to give the wisteria a nice open cut. As you’re cutting an opening across of it, make sure that a few inches will protrude from the ground. If you already opened it cut in the previous days, don’t hesitate to make another. You want the cut to be fresh. The deeper the cut, the better it is, so that the herbicide can penetrate the inside most portion of the wisteria.
Step #3 Peel it Off Nice and Slowly
You'll see a bark located near the stump of the wisteria. You want that bark to be peeled off. Peel it off until it's about an inch beneath the stump. This will make it easier for the herbicide to penetrate the entirety of the wisteria later on. You can use a simple pocket knife to peel it off down to the stump bark.
Step #4 Paint It
Bring out your paint brush and use it to paint the upper portion of the stump with your herbicide. Any paintbrush will do. However, it's recommended that you use a small one, so you won't paint on other parts. It'll also be less messy. Apply a lot of herbicide but make sure that it won’t be too much where it will be dripping off of it.
Step #5 Second Round of Painting
Once you’re done doing the initial painting process, you need to leave it there for an entire day – 24 hours to be exact. This amount of time will be enough to enable the herbicide to seep through the interior of the wisteria, along with its stump and roots. The next day, do another layer of paint on the stump. Just repeat the process.
Step #6 Finish Off the Wisteria
The waiting time for the wisteria to die completely is around one week to one month. It depends on the size of the wisteria, the climate, and the intensity of the herbicide you've applied. When you see that it's already wilting off and is already dead, then it's time for you to cut the stump off. Make sure that its roots are included when you pull it off the ground. This will ensure you that it wouldn't regrow in the future.
