How to Kill Wisteria Effectively & Easily!!
Are you looking for ways to control your wisteria? For the uninitiated, Wisteria is a genus of flowering plants of the legume family. It climbs by wrapping its stems around any available support. It can be a tree, pillar, gate, or any other structure. They can climb as high as 20m above the ground and spread more than 10m laterally.
It was the beauty and fragrance of this plant that attracted me first. After planting it in my garden, I was really proud of the way it spread! Soon, I started to find it annoying! It is a beautiful plant with decorative qualities. However, the problem is that given half a chance, it can grow into a problem!
Don’t allow the beautiful and sweet-smelling flowers fool you! Its beauty and fragrance are deceptive. It grows at a rapid speed and can easily take over other plants and even trees. It can completely take over a building or house if left unchecked. The largest known wisteria is in California, which measures more than 1 acre in size!
What Do You Need?
If you are looking for a way to effectively get rid of your wisteria, then read on. I asked a lot of gardening experts and the first time someone told me to kill my wisteria, I was shocked! Then I saw that I needed to do this to save the other plants and even a beautiful tree which was now completely covered in wisteria.
Here are a few things which you will need if you plan to kill your wisteria.
How Do You Control or Kill Wisteria?
Before we get into the details, you should understand that killing or eliminating the wisteria entirely is only the last resort.
1. Remove Sprouts or Plants by Hand
Sprouts: If the wisteria is still not too spread out, then you can try to pull out the new sprouts by hand. Make sure that you dig it out entirely so that it does not re-sprout. You should dispose-off all the branches and seed pods carefully so that no new sprouts come up in some other place.
Small plants: if the wisteria is slightly bigger, then you must cut it as close to the ground as possible. Put all the cuttings in a bag to dispose-off as far away as possible. Now put the herbicide on he exposed part left in the ground. If you notice any new sprouts after a few days, get rid of them immediately.
Big Plants: consistent pruning is the only way you can control wisteria. Regular pruning throughout the summer season to remove excess shoots is necessary. Extensive pruning during fall and winter can keep your wisteria under your control.
2. Use Herbicide
Prepare the Mix: use a disposable bowl to prepare the required amount of the mixture. It is even better to have a garden hose sprayer. You can find pre-mixed solutions like triclopyr and glyphosate, which are quite useful. You won’t have to worry about proportions and to mix. Add vegetable oil or diesel fuel for the herbicide to penetrate better.
Make the Cuts: the next thing to do is to make an open cut to your wisteria. Cut it a few inches from the ground. The cut should be fresh. It is better if the cut is deep because only then the herbicide can reach the inside portions of the plant.
Peel Off the Bark: look at the bark located near the stump of the wisteria. Peel off the bark until it is about an inch beneath the stump. This will ensure that the herbicide penetrates the wisteria completely. You can use the pocketknife to peel off the bark.
Apply herbicide: take the paintbrush and use it to apply the herbicide on the upper portion of the stump. Use enough herbicide to cover the exposed area completely.
Second Coat: after applying once, leave it for 24 hours or one day. During this time, the herbicide will seep into the interior parts. The next day, paint another layer of herbicide on the stump.
Kill Wisteria: after these steps, wait for a week to ten days for the wisteria to die. It also depends on how big your wisteria is and how strong the herbicide is? You will notice that the plant is wilting and dying. Now, it is time for you to cut the stump and finish off the wisteria completely. Make sure that you remove the roots and all signs of the plant fully.
3. Spraying Herbicide
Foliage: spray the foliage with herbicide only as a last resort. It may affect nearby plants.
Dipping: place the leaves or vine tips in herbicide solution for about 48 hours before cutting and removing the wisteria vine.
Some herbicides are specific to particular plants, while some are generic. It would help if you always used caution while using herbicides. Excess use can harm the surrounding areas, other plants and trees, and the environment in general. Follow the directions thoroughly and properly. Always try to minimize the use of chemicals.

Because of its quality of spreading too fast and becoming invasive in no time, it is a good idea to give some thought to where you want to plant it or where you must not!
