Winterizing Wisteria Plants Outside?

I live in Colorado, and bought new wisteria plants last spring and planted them in the ground in a sunny spot. I've read some other responses, but it didn't give me enough information for my particular situation. As far as I understand it, I shouldn't prune them, but leave them alone and keep them watered throughout the winter or leave them alone completely?

Winterizing Wisteria Plants Outside?
Hi:


Wisteria shrubs are deciduous and die out in the winter time. If your ground hasn't frozen yet, prune back the older branches. Always trim a branch at an angle. If you prune straignt across you could damage the tree.





You could add mulch to the shrub as this will help to the root system and to retain moisture.





If you haven't received much snow, go ahead and add a six month nitrogen slow release fertilizer to the base of the plant.





You can water some, but during the winter there isn't much of a growth pattern, so I tell my clients not to worry about it so much. Your roots are established, so you should be fine.





I hope this has helped some and if you need any other suggestions, please feel free to contact me at my website. I will link you to my properly pruning page as well as my site map. My site map has everything that is on the website. Good luck to you and have a great day!

Reply:Not sure what zone you are in but think they are hardy there. It is a good idea to let them be until the spring thaws.Then you can do some cleanup pruning if you need to. It wouldnt hurt to water them a couple of times during the winter. If you have a county extension agent there, they would be a good source of info for your exact area.
Reply:I live in the Southern USA where this plant is cultivated from and I have Wisteria Plants I am training into sculpture. I always prune whenever needed and even in winter but your location is different and may require to wrap in a heavy poly as much as is needed to prevent those week long freezes from killing off everything above ground.
