Calla Lily Care: Post-Bloom Dormancy and Reblooming

Understanding the Life Cycle

Calla lilies (Zantedeschia) are bulb plants. After flowering, foliage feeds the bulb, then dies back. The plant enters a mandatory dormancy period.

Step-by-Step Reblooming

1. While blooming: Keep in bright light, water regularly, fertilize weekly.
2. After flowers fade: Continue care until leaves yellow.
3. Dormancy: Stop watering. Store pot in a brown paper bag in a cool (50–60°F), dry place for 6 months.
4. Reawakening: Check weekly. When shoots appear, bring out, water, and resume fertilizing.

Key Tip

Outdoor summer placement in a tray of water with full sun maximizes bulb energy for next year's blooms.
