Winterizing a Wisteria

Question

I have a wisteria I bought this summer and put in a pot. I live in the Spokane, WA area. How can I ensure the plant doesn’t die over the winter? Do I need to have it buried in the ground or can I winterize it in the pot?

Answer 1

Wisteria normally do not make good container plants because they grow too big and too fast. But that being said, in terms of cold, if you live in Zone 5 or higher, it should be fine in a container with no extra care, but if you live in Zone 4 or lower, it will need extra protection. If you are in Zone 4, wrapping it in burlap and hay or leaves or moving it near a south facing wall should protect it enough for the winter. In Zones 3 or less, you would need to move it to a protected area, like an attached garage.

Established in-ground plants require little, if any care over winter. Here is more information on winter care for these plants: https://www.gardeningknowhow.com/ornamental/vines/wisteria/wisteria-winter-car.htm
