For small wisteria infestations, cut climbing or trailing vines as close to the root as possible. Although this may be labor intensive it is a feasible pretreatment for larger infestations or in areas where herbicides cannot be used. Because wisteria will continue to sprout after it has been cut, it should be cut back early in the season, cutting sprouts every few weeks until the fall. This will stop growth of existing vines and prevent seed production.
Wisteria vines should be removed from bases of trees and shrubs to prevent girdling as the trees and shrubs grow. In areas with established wisteria, a cut stump treatment is effective. A foliar application of glyphosate may be necessary for sprouts. For larger infestations of wisteria foliar herbicide applications may be necessary. To avoid damaging nontarget species, stump treatments should be administered before foliar treatments. Hi, I am doing some research into the possibility of building an arbour over my driveway and training a wisteria macrostachya blue moon to trail over it.
I will plant it with compost in a clayish we live on a delta soil 4 feet from a house foundation and 1 foot away from a cement driveway. It will get June sun from am pm and pm — pm daily. Our water table is only 5 feet down in summer and can be as high as 2 feet in the winter. My concerns: 1 that the plant drips sap on cars below the arbour.
I picked an American variety because I thought it less evasive. Hi, Gary, Great question! I bought a turn-of-the-century home in a very old Town with a beautiful half acre lot that has all kinds of old beautiful gardens and plants that have been left unattended. Unfortunately a whole side of my property has been consumed by a wisteria which I suspect is a Chinese or Japanese variety.
It is destroying everything in its path and the vines are hopelessly everywhere throughout the yard …back and forth as well as traveling up trees and and strangling them off. Is there any hope in removal? I feel totally hopeless as the vines just are unending. Please Help!! Hi, Jacqueline, Gardening questions can be tricky since the rules can change based on the region.

The scent is intoxicating and the masses of purple blooms are a marvelous harbinger of spring after a bitter winter.
For those of us who cannot afford a horticultural army, there is a happy alternative. Meet Wisteria frutescens, a sedate alternative to Asian wisteria that is native to the southeastern United States. But enthusiasm for native wisteria was overshadowed by the introduction of the bloom-heavy Chinese and Japanese varieties in the early nineteenth century. The blooms of Wisteria frutescens peak in late spring and early summer, often after the Asian variety fades, with shorter, more compact clusters of dark purple blossoms.
The house on Tradd Street where this frutescens above was photographed is one such example, with a relatively young vine climbing the iron gate. While this may temporarily favor some native species, it also stimulates vigorous growth and further spread of wisteria.
Prevention and Control For small infestations, cut vines to relieve trees of the weight and girdling; treat cut stems with a systemic herbicide containing glyphosate or triclopyr; new plants will grow from seed; long term management is needed see Control Options.
