How To Kill Wisteria Roots Naturally

A: I’ve been attempting to get rid of two wisteria vines that are five years old for a number of years. They keep coming back despite my attempts to cut them back to a stub, drill holes in the stubs, and use bleach, total weed kill, and other treatments. The vines are growing quite long shoots into the area around my pond. Help!! What can I do to entirely get rid of them?

A: Wisteria vines are very aggressive vines that require work and perseverance to eliminate, especially the Chinese (Wisteria sinensis) and Japanese (W. floribunda) kinds. The most of the suggestions have already been carried out, but you still need to keep performing them till the vine dies.

Most publications advise

  • As soon as fresh wisteria shoots grow, dig them up and pull out any roots that might be present.
  • Composting is not recommended because the plant can easily re-establish itself there and cause more issues. Instead, throw away any cuttings, vines, flowers, and pods.
  • Put a herbicide on the plant’s cut end. The best time to apply the herbicide is in the winter when the plant is dormant, though it can be done at any time. The stem will probably need to be killed by many treatments.
  • Any new growth should be pruned, and the herbicide should be reapplied.

The drilling method you employed before applying a herbicide is advised by another source. Drill holes into the wisteria stump and any lingering vines with a 1/8-inch drill bit that are at least an inch in diameter and about an inch deep. Place the holes at a distance of about one inch.

American wisteria (W. fructescens), a natural substitute, is significantly less aggressive. It is a shorter vine with milder smell and shorter racemenes (flower clusters). If you must have a wisteria but are worried about the invasiveness of the Chinese and Japanese types, Amethyst Falls is a particularly gorgeous variety that is widely available.

Q: Where these flowers are, my coworker wants to grow a garden. Do we have to immediately replant them if we dig them up now? Should we hold off until autumn? Or is this a time waster?

Elizabeth sent images of the flowers with her response. Daffodils, hyacinths, and what appear to be tulip leaves are all spring bulbs that I can see. After blossoming, spring bulbs need to refuel with food and energy. A few choices are as follows:

  • After the bulbs have flowered, dig them out and replant them right away so that the bulb can be replenished by the bulb greens.
  • Till the greens start to wither, leave the bulbs where they are. You can then dig them up, preserve them in a cool, dark place, and plant them again in the fall.
  • Till fall, leave the bulbs in place; then dig them up and replant them.
  • Toss them to a different gardener after you’ve dug them up.
  • When you dig the garden, give up on them and throw them away.

I had to tell you how simple orchids are to care for. A Wegmans orchid that blooms twice a year and has blossoms that last forever was a gift from my daughter many years ago. I maintain it near a west-facing window and give it once-weekly water, possibly more in the dry winter months. I therefore carried about 40 young orchids that I had purchased on one of the trips while I was in Hawaii. Since then, in 2010, I haven’t lost a single plant. If you give them the right light, they are actually the easiest plants to care for.

How can wisteria roots or vines be removed?

So how can you get rid of wisteria after it has grown too much? Wisteria removal might be difficult, but there are various methods you can try. Start by manually picking or digging up any sproutlings. To stop the wisteria from resprouting, cut it to the ground. All wisteria branches (and seed pods) should be bagged up and disposed of to prevent the possibility of new sprouts appearing elsewhere. Then, for permanent wisteria eradication, apply a properly formulated herbicide, such as a non-selective kind.

To the stump, paint or immediately apply the pesticide. You might wish to re-treat them if more sprouts appear in the future. Spraying the foliage should only be done as a last option to protect surrounding plants.

Before cutting and removing the wisteria vine, some people instead opt to soak the leaves or as much of the vine’s tip as possible in a herbicide solution for around 48 hours. Although the majority of herbicides are intended to target certain plants without damaging other vegetation, you should still exercise caution when using them.

For the correct application, please follow the instructions. The optimum time to apply herbicides to eradicate wisteria is in the late summer or early fall. But removing wisteria is probably simplest in the cold.

You shouldn’t encounter too many issues as long as you know how to prune wisteria on a regular basis to keep it under control. Cutting it down and soaking what’s left in an appropriate herbicide may be your only option if your wisteria has grown out of control or if you simply don’t want it.

Recall that organic methods of control are more environmentally friendly and should only be employed as a last option.

What may be used to kill wisteria?

The most effective technique against both old growth and new sprouts is typically chemical, although even this will require patience and commitment.

The only real natural approach to kill wisteria is probably to completely and carefully excavate the area.

It will either be administered using a sprayer or a paintbrush, depending on the herbicide.

  • Once the leaves start to change color in the fall, you can use RoundUp (also known as glyphosate) on wisteria.
  • Cut the vines back to about ground level, then spray the freshly cut stump with a concentrated RoundUp product designated for wisteria.
  • By adding concentrated RoundUp to flower picks, you can increase their effectiveness by twofold.
  • Put the picks into the ground so that the point punctures the roots of your wisteria and delivers the poison to the plant.

A reliable brush killer, such Remedy Ultra, will slow the growth of wisteria over time.

After a decent amount of time, if herbicides still don’t seem to be working, you might decide to fight climbing vines with techniques used to combat English ivy. Details about English ivy removal.

This includes combining a little amount of diesel fuel with the herbicide, but due to the risk of fire and the environment, this method should only be used sparingly.

Peeling the vines’ bark and painting commercial-grade bleach on it is another last-ditch solution that works but can harm other plants.

This procedure should not be used around other plants for obvious reasons since bleach may pollute the soil.

How can the roots of wisteria be stopped from growing?

Pruning wisteria twice a year is the best approach to prevent it from growing out of control. After the flowers have faded in the early to mid-summer and when the shoots from this year’s growth begin to look untidy, the first pruning should be done. The goal is to remove undesired shoots or suckers and to keep new development close to the main vine as follows:

  • Trim fresh growth shoots to a length of 6 inches.
  • Suckers at the roots should be removed.
  • Cut off any sprouts that the vine’s main support structure doesn’t require.

Since flowers only appear on one-year-old growth, this pruning strategy not only keeps the vine in a tight shape but also enables the blooms to be seen the following year.

Why does wisteria die? The top?

According to the University of Florida IFAS Extension, the next step is to apply a pesticide after removing the undesired Wisteria runners and chopping the plant down to the roots. Triclopyr-containing herbicides work best to eradicate wisteria, and several popular brand names are included on this list, such as Enforcer Bush Killer, Bush B-Gon, and Brush Killer-Stump Killer. The majority of home and garden stores have many. After cutting, immediately apply the herbicide to the stump. Always follow the product’s label directions and safety advice.

Other plants, both desirable and unattractive, may also be impacted by these compounds. Triclopyr, however, is a nonselective herbicide. As a result, the Missouri Botanical Garden reports that the best herbicide to kill Wisteria is also the best one to destroy other plants, such as Japanese honeysuckle (Lonicera japonica), which thrives in USDA zones 4 to 9. Herbicide use must be done carefully and safely to prevent harm to or death of other, more valuable plants.

How do I remove a sizable wisteria?

These suggestions are aimed for local governments and homeowners who want to begin improving their neighborhood greenspace. Although we have introduced a herbicide option for select species for individuals who are comfortable using them, we always encourage herbicide-free control strategies for each species. These techniques were chosen with consideration for minimizing soil disturbance, minimizing pesticide use, and preventing injury to any potential coexisting species, whether they be plants or animals. All of them can be manually removed if you have the time. If the infestation is really bad or if these suggestions don’t work, we advise that you look into competent expert services.

Chinese Wisteria & Japanese Wisteria

EPPC Category 4 Wisteria floribunda in Georgia (naturalized in Georgia or in need of further information)

Wisteria is quite challenging to manage. Check out expert control if the infestation is dense.

Cut and Treat

To access sunlight, wisteria climbs tall trees and constricts itself around their trunks. These vines encircle the tree as it spreads outward. Sever vines at the base of trees to halt this. Avoid attempting to pull vines that are out of your grasp down. The vine above the cut will die if you cut it at the base, and it will ultimately dry up and fall off.

Follow the vines to the ground, make a base cut with a handsaw, and then treat with herbicide. To maintain track of what has been treated, we employ a high concentrate (between 20 and 50 percent) glyphosate-based solution with an indicator dye. Make certain to just spray the pesticide on the wooden stem. In order for the herbicide to be absorbed, you must treat the wound within 5 to 10 minutes of it becoming dry. Only stems with a diameter of 0.5 or greater should be treated.

How to Identify Invasive versus Native Wisteria

Wisteria is probably an invasive species if it blooms in the early spring. Because spring is coming early owing to climate change, Japanese and Chinese wisteria (Wisteria floribunda and Wisteria sinensis) may blossom even earlier in April or May. Native to North America, Wisteria frutescens blooms in June and July.

Here are some hints for distinguishing between them:

  • Due to a thick layer of small hairs covering them, the pods of Asian Wisterias have velvety textures. The smooth, hairless pods of the American Wisteria are.
  • While native flowers bloom at the base and move upward on the flower stalk, flowers on Asian variants bloom all at once.
  • While the American wisteria has a more rounded tip, the Japanese and Chinese wisteria have pointy leaf tips.
  • The Chinese and American species both twine in the opposite direction. Clockwise twining of Japanese wisteria.

Magnolia Collection

The lineage of flowering plants that includes magnolias dates back about 95 million years. There are 18 different varieties of magnolias, from flowering to evergreen, in the Atlanta BeltLine Arboretum. When the Atlanta Crackers played baseball at the former Ponce de Leon Park, two unique magnolias were planted right outside the outfield wall. Home runs hit by Babe Ruth and Eddie Matthews were both caught in the magnolia tree’s canopy. In order to preserve this piece of history on the Atlanta BeltLine Arboretum as well as in new parks and baseball fields across Atlanta, we have taken cuttings from these old magnolia trees and grown them into new trees as part of Arboretum experiments.


The oak trees on this hillside and across the Arboretum illustrate a variety of Georgian environments, from granite outcrops to bottomland hardwood swamps. 33 of the approximately 90 native oak species in the United States are found in Georgia. On this slope, 33 oak trees are growing, and between them, one stainless steel leaf sculpture represents each tree.

The Landis Sculpture Studio’s David Landis created and created these metal trees. Click here to read more about David’s work. See our fact sheet here for more details on the specific oaks featured.

Beech Circle

Beeches, one of the most regal of our natural trees, are a sign of an established forest. Beech trees are essential for animals, despite the fact that it can take them up to 40 years to produce a significant amount of nuts. All different species of birds and mammals, including the red-headed woodpecker, can find food and refuge in beeches. A circle of beech trees known as the “fairy ring” surrounds a granite gathering and outdoor classroom where you can imagine how the beech trees will seem in three, five, and ten years.

Eastside Azalea Collection

Despite being Georgia’s official state wildflower, the natural azalea is rarely employed in landscaping. With more than 300 azaleas on exhibit, the Atlanta BeltLine Arboretum now has the largest native azalea collection available to the general public in the Atlanta area. All 13 of the Georgia’s native azalea species are present in the collection, which features more than 25 different species, cultivars, and variations. This collection concentrates on named cultivars from two series, the Georgia Moon Series and the Sunrise to Sunset Series, that have been chosen for their characteristics such as color, size, bloom time, etc. The Georgia Moon Series will feature fragrant white-blooming native Georgia species, and the Sunrise to Sunset Series will have warm orange, red, and soft yellow native Georgia species that bloom from March through July.

Stumpery Garden

The Stumpery Garden is a horticultural oddity that offers a space for the general people to learn and explore while also showing how trees may be used in attractive ways. Stumpery gardens make use of storm-damaged, dead, fallen, and dead trees as a resource for the garden, offering vital habitat for beetles, amphibians, birds, and small animals like chipmunks. Logs, branches, and pieces of bark are arranged to create walls and arches, and whole logs are turned upside down to reveal their root system. They foster the growth of ferns, lichen, mosses, soft grasses, and trailing plants on and around them.
