Winter Storage for Calla Lilies in Cold Climates (Canada)

Dig, Dry, and Store for Spring Replanting

Calla lilies (Zantedeschia) are frost-tender. In Saskatchewan, they must be lifted.

Procedure

1. After first frost, cut stems to soil level.
2. Dig carefully; brush off soil (don’t wash).
3. Air-dry in shade for a few days.
4. Store in brown paper bags (not plastic) in a cool (50–60°F), dark, dry place.
5. Replant after last frost in spring.

Reality Check

Expect some losses the first few years. Overwintering is a skill—practice makes perfect.
