Overwintering Calla Lilies: Digging, Curing, Storing, and Spring Replanting Guide

Calla Lily (Zantedeschia) Winter Storage

After frost kills foliage:

1. Dig rhizomes carefully with a fork; shake off soil.
2. Cut stems to 2–3 inches.
3. Wash gently; air-dry 1–3 days in shade.
4. Store in paper bags with slightly damp peat/vermiculite at 50–55°F.

Spring: Divide rhizomes (each piece needs an "eye"), dust cuts with sulfur, let callus 2–3 days, then plant 3–4 inches deep after soil warms.
