Can You Kill Wisteria By Pruning

So let’s get started. When should wisteria be pruned? Wisteria should be pruned once in the winter and once more in the summer. You should prune your wisteria in the summer approximately two months after it blooms.

In order to properly trim a wisteria, you must first understand that regular pruning is necessary to regulate growth and promote more blossoms. The current season’s shoots are pruned back to three buds from the root. The new shoots and blooms for the upcoming season will then emerge from these buds.

Wisteria that has grown too large can also be pruned. The best way to trim the wisteria in this situation is to lop and cut as much as you like, down to around 3 feet (1 m), or where you truly want the wisteria to be. In this manner, you will have lovely new shoots the next spring as new sprouts appear and it develops to that height. When you prune wisteria in this way, keep in mind that doing so will prevent any flowering for several years as the new shoots mature once more.

You’ll discover that trimming the wisteria may have caused some of the larger branches to die back. This is fine. You can simply remove them from the plant or completely prune them back. It occurs. You cannot change the situation much, unfortunately. Have no fear. The plant won’t die as a result.

When it comes to wisteria trimming, there are occasions when some people believe that persistent wisteria cutting, especially if it hasn’t bloomed in a while, will eventually cause an older wisteria bush to bloom. Though it might be worth a shot, this might or might not be true. Wisteria can generate new growth as a result of trimming, and the flowers will eventually appear on this growth. Your aim might only be accomplished after a few years.

Some people think that cutting the roots with a shovel is the best approach to trim wisteria, especially an older one. According to them, doing so actually aids the plant in absorbing more nutrients from the soil and finally blooming. Again, because you most likely cannot kill it, feel free to try this approach as well!

What method of wisteria control works the best?

Q. I need help killing a wisteria vine that has taken over my entire yard.

A. Wisteria has deep roots, so even if you simply cut the vine off at the ground, it will keep growing again.

Use Roundup or Kleenup as directed on the label for the best results in permanently getting rid of wisteria. These herbicides can be sprayed on the leaves, but if any drift onto the foliage of desired plants, it could also kill those. Don’t spray while it’s windy.

The main stem of the wisteria can be safely cut; the cut end can then be painted with a little coating of normal-strength herbicide. Wearing rubber gloves will help you avoid getting the liquid on your skin. The chemical will be absorbed by the vine and go to the roots, where it will cause death. Given how quickly this plant grows, two treatments might be required.

Q. It seems like every year I have more and more issues with moles tunneling through my entire yard. How do I solve the issue?

Can I remove the wisteria completely?

If the wisteria plant has a lot of dry, old branches and appears to be highly out of shape, it can be severely pruned back.

In order to renovate the plant, it is occasionally necessary to remove every branch, all the way to the main stem or even to the ground. Your wisterias will be inspired to grow new, robust branches as a result of this severe trimming.

McKenzie cautions that while the growth will be of much superior quality, the wisteria may not blossom for two or three years following a hard cut back.

A new pergola or arch can be created by “hard pruning” in addition to retraining the plant.

How can wisteria vines be removed?

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.

“The term “category” refers to a definition of invasiveness based on data from the Exotic Pest Plant Council (EPPC) of Georgia and North Carolina and does not always reflect the intensity of invasions in Atlanta specifically.

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.

How can wisteria be eliminated 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. Although it can be done any time, the best time to apply the herbicide is in the winter while the plant is dormant. 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.
