In the fall, dig up the rhizomes, cut the stems back to 2 to 3 inches, and let them dry.
Leave them in a box in a cool part of the house where they will not freeze, such as a basement where the temperatures range between 40 to 50 degrees.
Finding that place where the temperature is between 40 and 50 can be a challenge. Most basements are warmer than that and most garages are colder than that.

They recommend washing dahlia tubers (bulbs) before storing. Then store them the same as cannas. In addition, check the dahlias occasionally for rot.
In cases where tuberous roots like dahlias have some rot, cut back until you reach clean white, fleshy tissue again. These structures may need attention and care even during their dormant period.
