canna survive in your garage in z5 ... wow .. just goes to show how variable z5 is...

just tip them on their sides ... in full shade for winter.. all the better if they get covered with snow ...

you dont want them to freeze solid... then accumulate water.. making a giant ice cube out of the media.. roots need air ...

or unpot.. heal into veg patch.. repot in spring ... again.. a water accumulation thing ...

Thanks, Ken.

I do over-winter my cannas in the garage, Ken. I keep them in plastic pots, let them die then cut them about 3" above the soil. Then I wrap the pots in bubble pack and cover with brown paper bags. I leave them in the pots in the garage all winter, then start bringing them out in April. At that point, it's pretty much a labor of love to put them outside during the day and bring them back inside at night. It's a lot of work, but I just love them.
