Calla Lily Yellowing Leaves: It's Dormancy, Not a Pot Problem

Yellowing = Natural Rest Period

Calla lilies (Zantedeschia) enter dormancy after blooming. Yellowing, dying leaves are the plant withdrawing energy into the rhizome. Repotting now would disrupt this cycle.

Dormancy Care (3 Months)

1. Stop fertilizing.
2. Reduce watering – Just enough to keep soil from bone-dry (once a week).
3. Move to cool, dark, dry place – 50–55°F (10–13°C) ideal. Basement, garage (if frost-free), closet.
4. After 3 months – Bring to warm, bright window; resume water/fertilizer. New growth emerges.

Repot Later

When new shoots appear, then move to a larger pot with fresh mix. The plant will use the new space for active growth.

Don't fight dormancy—it's essential for next year's flowers.
