I'm setting up/planning water features for the summer and wanted to bring back a canna I had partially submerged in a water feature last year. It overwintered in a plastic bag in the garage (temps 40-50) and while it looks pretty sad, I think its roots are viable.
Should I wake it up early? Our last frost date is 6/15 and things get really toasty in July. I don't want to submerge it in warm water (on a heat mat or whatever) if I'm going to cause the roots to rot. Should I try to do this? I don't know how long they take to wake up, if they do, or if they appreciate help. I also don't want to wait too long and find that it's not viable a month from now.
