Cannas are tough as nails so if you want you can do it now.

Yep, I don't know if you can kill them. My neighbor had dug up a bunch last year and they were out in the full blast heat with no dirt inside a can with a lid for about a week and she mentioned she had forgotten to put them out with the trash and I asked for them. stuck em in a pot and a week later they were a foot tall, lol.

Thanks for your speedy response. I'll get to it tomorrow!
