I was given a wonderful gift of cannas this past May or so. I gave them lots of love. I put two of them in what I thought was a large pot. Now my problem is that, once the leaves got burned by frost I tried to get them out of the pot, and they are so robust they are wedged in. I have a BUNCH of what look like bulbs - incredibly healthy. And I don't quite know what to do.
If I take the entire pot into the house and to my basement (60 degrees) will they rot? Can I hope that the soil will dry or that they will dry in order to allow me to lift them once it does dry? I am in zone 5a and cannot leave them outside. And lastly, will they explode my ceramic pot if I can't get them out and they continue to grow?
Any help would be greatly appreciated. I am attaching three pictures to show you the extent of the growth.
