Are The Big Blooms Of The Invasive Japanese Wisteria Really Worth It?

0 5

Japanese wisteria is a long-lived and strong vine that can crush fencing and kill trees that it climbs on. Once established, Japanese and Chinese wisteria are notoriously difficult to remove and can quickly take over yards and forests, outcompeting native plants. The vines not only compete for soil nutrients but also grow over the top of trees, preventing the host plant from receiving enough light. Additionally, because wisteria vines are so strong, they can damage the bark around a tree they climb on, eventually killing the tree, making it essential to learn strategies for removing these invasive vines.

As gardeners who have tried to get rid of wisteria can attest, when wisteria vines are cut back, they can quickly grow back from even small portions of roots. The University of Florida recommends “painting” glyphosate over the stem after cutting to prevent regrowth. Wisteria can also be removed by digging up the whole plant. Unfortunately, this strategy may not be realistic for established plants with large root systems.
