Calla Lily 'Picasso' Gift Plant: Repotting, Dormancy, and Cellar Storage Light

A potted calla lily ('Picasso') will finish blooming, then foliage yellows as it enters a 3-month dormancy.

Immediate Care

• Keep watering until foliage withers completely.
• Then stop watering; move pot to cool (45–55°F), dark, dry place (basement, garage).
• Store 3 months; check monthly—soil barely moist.

Light During Dormancy

For tuber/bulb storage, total darkness is not required. A basement laundry light used occasionally won't harm dormant tubers. (Unlike poinsettias, which need strict 14-hour darkness to rebloom.)

Reawakening

After 3 months, bring to bright light, resume watering, feed with bone meal. Plant outdoors in Zone 6+ after frost; in Zone 5, keep in pot and overwinter indoors.
