Correct Winter Storage for Canna Rhizomes (Not Crepe Myrtle)

Cannas Need Cool, Dry, Ventilated Storage

Hardy only to Zone 7. In colder zones, lift after first frost.

Storage Steps

1. Brush off soil; don’t wash.
2. Dust with antifungal powder (optional).
3. Place in ventilated container: onion bag, net bag, or cardboard box with holes.
4. Store in cool (40–50°F), dark, dry basement or garage that doesn’t freeze.
5. No refrigeration—cold damage kills rhizomes.

Spring Planting

Replant after frost. Cannas are heavy feeders—amend soil with composted manure.
