Evergreen Wisteria

Question

We just purchased a home and there is an evergreen wisteria growing on a trellis – it was not cut back in the fall and is starting to get out of control. Is it ok to cut this back even though it’s the start of spring?

Answer 1

You are not to late to prune. In fact, the flowerbuds of wisteria are produced during the summer (on last year’s wood), so wait until late spring or early summer to prune the vine back. Pruning the previous year's growth too severely will remove the flower buds, but that is rarely the case. Most people do not prune severely enough. Severe pruning is often recommended, back to three or four buds, to keep the plant manageable and renewed.
