Calla Lily Winter Dormancy: Forcing Rebloom

Your yellow calla lily (Zantedeschia elliottiana) is entering its natural winter dormancy. Yellowing, drooping leaves and bending stems signal the need for rest—not more water.

Dormancy Protocol

1. Stop watering completely. Allow soil to dry fully.
2. Store the pot (or bare rhizomes) in a cool (40–45°F), dark, dry place for 8–12 weeks.
3. In January–April, bring out, repot in fresh mix, and gradually increase water and temperature.
4. Place in bright light. New growth emerges in weeks.

Reality Check

Many discard callas after flowering because reblooming indoors is challenging. If you lack a cool storage spot (unheated garage, basement, refrigerator crisper), success is unlikely. Enjoy the foliage while it lasts, then compost or attempt dormancy as an experiment.

Alternative

Treat as an annual. Purchase new flowering plants each season—often easier and more reliable.
