What is the lifespan of a wisteria plant?
Additionally, individual wisteria plants can live for more than 50 years; wisteria’s longevity only increases its ability to invade an area and choke out native plants. Prune your wisteria twice a year to keep it in check and make sure you get lots of magnificent flowers each spring. Remember that sunlight needs to reach the wood at the base of younger plants in order for it to ripen and produce flower buds.This problem has some causes and some solutions. The common complaint can often be traced to something as simple as a poor plant or a poor site. Perhaps a wisteria plant is not getting sufficient light, which is six or more hours of direct sunlight. Wisterias propagated from seed have to be mature enough to bloom.
How long does it take for a wisteria tree to grow?

What happens if you don’t prune wisteria?
If left unpruned, wisterias will ramble and grow to immense size, but will not flower as profusely. Summer pruning improves the air circulation through the plant which is beneficial to plant health. It also allows more sunlight to reach the base of the shoots which encourages wood ripening and flower bud formation. Regeneration of trees and understory vegetation is decreased by smothering and shading. Wisteria vines can climb over existing vegetation and topple large trees, creating canopy gaps that further favor infestations.A Wisteria tree is a specially trained Wisteria vine pruned into a single-stemmed tree form. Unlike sprawling Wisteria vines that need trellises or fences for support, Wisteria trees feature a strong central trunk and a cascading, umbrella-like canopy that blooms in early spring with fragrant, hanging flower clusters.Wisteria can suffer from root diseases such as honey fungus and Phytophthora root rot. Roots of container plants in particular can suffer damage from vine weevil grubs.Wisteria shouldn’t damage strong foundations because their roots grow mostly down, rather than spreading wide. Standard plants will grow up to 3 foot below the ground, but older, mature plants can grow as deep as 10 feet. Generally, they will turn away or grow around solid obstacles, like foundations.
