Canna and Dalhia bulbs. Should they be dug up for winter and stored?

I live in Northwest Indiana and this summer I planted Canna and Daliah bulbs. Should they be dug up and stored for the winter? They are not planted very deep in the ground and I am afraid the bulbs will die from freezing.

Yes. Dig them up and place the roots/tubers AS WELL AS THE TOPS on some newspaper in a cool, dry, dark place for about a week so they can dry out. Then cut the tops off and place the roots/tubers in paper bags (preferred) or perferated plastic bags with some vermiculite. Store them in a cool, dark, dry place for the winter.
Reply:YES! They will definately freeze if you leave them.
Reply:Your reasoning is correct; they could freeze.


For your zone you will need to dig them up.
Reply:This is why I don't plant Glads, Dahlias or Cannas. Pretty to look at, but I have difficulty with their survival after digging them up.





Even my Amaryllis won't cooperate. I've had it in a dark, dry place since New Year's and the dumb thing still sends off shoots!
