If you live in a climate that gets freezing temperatures, you need to dig up the canna tubers and bring them into a place where it does not get lower than 45 degrees, such as a heated garage, root cellar, or crawl space. Dig the tubers up, wash them, sprinkle them with sulfur powder, and wrap them in burlap or saran wrap. Plant them after danger of frost.
