Winterizing a Wisteria
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?

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
