My Cannas have rust - no doubt about it.

They die back for the winter here in central FLA. We leave the rhizomes in the ground, and they come up again in the spring.

My question is, will they have rust when they come up again next spring?

Would it be worth the trouble of digging up the rhizomes, treating them with a fungicide, and storing them for the winter? Or just leave them, and hope the rust fungus dies off with the winter?

I Googled canna rust, but I can't find anything on it.

I appreciate your help.
