Canna's

Paul CSPaul CS Posts: 13
My Canna's are still looking good. I'm in a mild climate area, should I let them go over winter or can I cut them back?
If possible I'd like to cut them back before Christmas to allow spring flowers through.

    I think when people are able to leave them out, they cut back and mulch them, or use fleece. 
    I think if you don't cut them back, there's a danger of soggy foliage getting into the crowns and causing rot. Wet cold isn't good for them.

    I might be wrong though. Not something I can do - they need protection inside here in winter.  :)

    Thanks for your reply. So when should I cut them down do you think, when all foliage has died?

    I'd guess that would be the time.
    As I say - not something I've ever had to do, but when I brought mine into the house or conservatory, I took the main stem off once it looked hideous, and was of no benefit. 
    I wonder if some other forumites might be better able to advise though. 
    @punkdoc grows them.

    I am in a fairly cold area, but what I have done for many years, is to lift them anytime from now, cut them back and store them somewhere frost free and very slightly damp.

    They are less hardy than Dahlias, so unless you are in a very mild location, digging them up would be best.
