Rescuing a Valentine's Calla Lily: Dormancy, Not Death

A gardener repotted a yellowing Valentine's calla lily into Miracle-Gro soil, placed near a back door (indirect light). Feared it was dying.

It's Not Dying—It's Going Dormant

Colored callas (Zantedeschia hybrids) bloom 8–12 weeks, then must go dormant. Yellowing leaves = normal transition.

Correct Care Now

1. Stop fertilizing. Miracle-Gro is too high in nitrogen.
2. Water sparingly as leaves yellow. Let soil dry between waterings.
3. When leaves are brown: Cut off. Stop watering almost entirely.
4. Store pot: Cool (50–60°F), dark, dry. 2–3 months.
5. Rebirth: Move to bright light (6 hrs indirect). Resume water. Feed bone meal.

Light & Soil Fixes

• Light: Calla needs 6 hrs bright indirect. Your back door may be too dim. East/west window better.
• Soil: Miracle-Gro holds too much water. Next dormancy, repot in peat/perlite/bark mix.
• Outdoor option (NC Zone 7–8): Plant in ground after last frost. Part sun, well-drained. Will naturalize.

White Calla (Z. aethiopica) Difference

White callas are evergreen in mild climates. Don't force dormancy. But colored hybrids require it.

Your plant is normal. Let it sleep. Wake it in summer.
