How to Kill Wisteria? – An Ultimate Guide

To kill wisteria, you need to cut it back to the ground and apply herbicide. Wisteria is an invasive plant species that can take over your lawn or garden if not properly maintained.

It can grow up to 10 feet per year and forms dense thickets that choke out other vegetation. To effectively control wisteria growth, you should prune the plant down to about 6 inches above ground level. This is best done in late winter or early spring. Immediately after pruning, apply a type of herbicide that contains either glyphosate or triclopyr. Be sure to follow the instructions on the herbicide label for the correct application rates and timing. With these efforts, you’ll successfully get rid of wisteria and protect your garden from its aggressive tendencies.

Understanding Wisteria’S Growth And Structure

If you have a wisteria plant in your backyard, you likely know that it’s a beautiful plant that produces stunning, cascading blooms. However, you might also know that wisteria can be an aggressive grower, and if left unattended, can climb and spread across other trees and structures in your garden.

To control your wisteria’s growth and keep it looking its best, you need to understand its life cycle, anatomy, and pruning requirements.

The Life Cycle Of Wisteria: What You Need To Know

Understanding wisteria’s growth cycle is crucial if you want to keep your plant healthy and thriving.

  • Wisteria is deciduous and loses its leaves each fall.
  • In the spring, wisteria produces new growth in the form of leaves and flowers.
  • Wisteria blooms once a year, usually in the spring or early summer.
  • After blooming, wisteria produces long tendrils that can stretch and grow rapidly.
  • These tendrils produce buds that become the next year’s blooms, starting the cycle over again.

The Anatomy Of Wisteria: Understanding Its Root System, Stems, And Leaves

Understanding wisteria’s anatomy is essential if you want to prune your plant correctly.

  • Wisteria has a deep root system that allows it to thrive in many types of soil.
  • The stems of wisteria plants are thick and woody, often reaching several inches in diameter.
  • The leaves of wisteria plants are compound and can have up to 19 leaflets on a single stem.
  • Wisteria produces the purple, blue, pink, and white blooms that are famous for hanging and dangling from vines that produce a fragrant smell.

The Importance Of Pruning Wisteria: When And How To Do It

Pruning your wisteria is essential to keep it from growing out of control and producing fewer blooms.

  • Prune wisteria in late winter or early spring before it produces new growth.
  • First, prune away any dead or damaged growth.
  • Next, prune back long tendrils to 6 inches long, cutting just above a bud.
  • Remove any suckers or growth from the base of the plant.
  • Train the remaining growth to grow horizontally along a trellis or other structure.

By understanding wisteria’s life cycle, anatomy, and pruning needs, you can keep this beautiful plant under control and looking its best. Give your wisteria the care it needs, and you’ll be rewarded with stunning blooms year after year.

Non-Chemical Methods To Kill Wisteria

Wisteria is a beautiful plant that’s known for its fragrant, purple-violet flowers. However, if left unattended, it can quickly become invasive and take over other plants, trees, and even your fences and walls. The best way to get rid of it is by using non-chemical methods.

In this post, we’ll discuss how you can kill wisteria using pulling out the roots, smothering it, and suffocating it.

Pulling And Digging Out Wisteria Roots: Tips And Tricks

Pulling out wisteria roots, especially if it’s a mature plant, can be difficult.

  • Start by cutting the plant down to ground level using a sharp pair of garden shears.
  • Use a shovel to dig around the plant, making sure that you’re digging deep enough to get to the roots.
  • Try to loosen the soil around the roots by rocking it back and forth.
  • Pull out the roots using a pair of pruning shears or a digging fork.
  • If you’re dealing with a large plant, you may need to repeat this process several times until you’ve removed all the roots.

Smothering Wisteria: Materials And Techniques

Another effective way to kill wisteria is by smothering it.

  • Cut the plant down to ground level as close to the soil as possible.
  • Cover the area with a layer of cardboard or newspaper. Make sure you completely cover the entire area, including the plants’ stems.
  • Add a layer of mulch on top of the cardboard or newspaper, making sure it’s at least 5 inches thick.
  • Keep the area moist, but not wet. You should start seeing results in around six months, and hopefully, the plant will die completely in a year.

Suffocating Wisteria: Best Practices To Kill Wisteria Without Chemicals

Suffocating the plant is an effective way to kill wisteria without using chemicals.

  • Cut the plant down to ground level
  • Using a sharp pair of pruning shears, cut all the stems as close to the soil as possible.
  • Cover the area with a heavy-duty black tarp, making sure it’s secured with rocks or bricks. You should leave it in place for at least one year.
  • After one year, remove the tarp and check if the wisteria has died completely. If not, put the tarp back in place and wait for another six months to one year.

Killing wisteria is not an easy task, but it’s possible, and the non-chemical methods mentioned above are an excellent way to do it. Just remember that it may take time and effort, but with persistence, you can effectively kill wisteria without harming the environment or using toxic chemicals.


Chemical Methods To Kill Wisteria

Wisterias are stunning and charming plants, but they can be invasive and detrimental to other plants’ growth around them. If you have decided to remove wisterias from your garden, you need to know the proper methods to do so. This section of the article focuses on chemical methods to kill wisteria.

Understanding Chemical Herbicides: What You Should Know

Chemical herbicides are an effective way to remove unwanted plants from your garden. However, it is essential to understand the nature of herbicides to use them correctly.

  • Herbicides are chemicals designed to kill plants.
  • They can be selective or non-selective.
  • Selective herbicides only target specific plant species, while non-selective herbicides kill all plants.
  • Herbicides work by interfering with the plant’s metabolic functions, preventing them from growing.

Glyphosate: The Most Effective Herbicide To Kill Wisteria

Glyphosate is a non-selective herbicide that works by inhibiting a specific enzyme in the plant that is essential for growth. It is the most effective herbicide to kill wisteria since it is a perennial plant and requires a full application.

  • Glyphosate is a systemic herbicide that requires full application to the plant’s leaves and stems to work.
  • The ideal time to apply glyphosate is in late summer or early autumn, when the plant is actively growing.
  • Avoid applying glyphosate on a windy day to prevent the herbicide from affecting the surrounding plants.

Treating Wisteria With Herbicides: Dos And Don’Ts

It is essential to take precautions when using herbicides in your garden.


  • Wear protective clothing such as gloves, long-sleeved shirts, and pants when handling herbicides.
  • Follow the manufacturer’s instructions when applying herbicides.
  • Mix the herbicide as per manufacturer’s instructions before applying it.
  • Wait for a few days before removing the dead wisteria.


  • Never touch, inhale, or ingest herbicides.
  • Do not apply herbicides near water bodies or on windy days.
  • Do not spray herbicides on other plants.
  • Do not apply herbicides if rain is expected within 24 hours.

Using chemical herbicides to kill wisteria can be an efficient and effective method, but it is crucial to follow the guidelines and precautions mentioned above. Understand your herbicides, use the most efficient one, and take the necessary precautions you need to take.
