Q.Wisteria vines in large planter over winter
I just planted 2 Wisteria vines in separate planters 2 feet square by 18″ deep. Will they survive the winter in planters or do they absolutely have to be in the ground? If not, is there something I can do to help them survive the Canadian winter in planters? Thanks and have a great day!

I would recommend a much larger container for your Wisteria.
Half whiskey barrels are a good choice and most garden centers carry them.
Wisteria is hardy to zone 5.
Perhaps a cold frame structure would protect them enough through the winter but it is a gamble at best.
