Troubleshooting Calla Lily Leaf Curl and Yellowing

Common Causes of Calla Distress

1. Aphids or Spider Mites

Inspect leaf undersides for tiny insects. Wash off with strong hose spray or use horticultural soap.

2. Watering Issues

• Pots on ground may not drain if soil beneath is compacted.
• Elevate pots on feet or gravel.
• Miracle-Gro Garden Soil with fertilizer may be too rich; stop feeding for a month.

3. Natural Dormancy

After blooming, callas yellow and die back for a 90-day rest. If plant has bloomed, this is normal. Reduce water, store cool and dark, then restart.

Diagnosis Steps

1. Check for pests first.
2. Verify drainage.
3. Assess bloom stage.
