I would like to know if I can plant calla lilies and tulips in pots for next spring? The size of the pots are 18 inches tall and 10 inches wide. Our temperature goes below -40 in Alberta, so I am scared of leaving them in ground. Can I take all my pots in the basement? It is going to be frosting weather maybe next week. I am not sure what to do.

You can treat the callas similar to the tulips.
