Reviving Dormant Calla Lilies and Caring for Arum Lilies

Calla lilies (Zantedeschia) grow from rhizomes that require a winter rest. If the foliage dies back, the plant isn't dead—it's dormant. Stop watering, place the pot in a cool, dark spot for three months, then bring it into bright light and resume watering. Feed weekly with half-strength bloom fertilizer once growth resumes.

Jump-Starting in Late Winter

If dormancy has lasted three months (e.g., late August in the Southern Hemisphere), move the pot to a warm, sunny window. Water lightly with fertilizer solution until shoots appear, then increase watering.

Arum Lily (Peace Lily) Care

Arum lily (Spathiphyllum) is not a bulb and has different needs: bright indirect light, allow the top inch of soil to dry between waterings, and never let it sit in standing water. It thrives with minimal fuss.
