My husband and I just bought our house. It has a severely overgrown wisteria arbor. We live in Virginia and it is now December… however we are just now having 50° days on average. The leaves are all gone off it. The realtor said it hasn’t bloomed for several years. Can we cut it back and reshape it somewhat now? I am afraid that if we do not cut it back some, we could get a heavy snow and the entire arbor may come down along with the wisteria. Please tell me we can trim it back without damaging it too much. What can I do to encourage flowers next spring?
Yes, you may cut the wisteria back pretty hard. They can withstand quite a bit of abuse! Here is an article that will help: https://www.gardeningknowhow.com/ornamental/vines/wisteria/pruning-wisteria.htm
