Overwatered Peace Lily: Root Rot Diagnosis and Recovery

Peace Lily (Spathiphyllum) sat in 3" of water → root rot. Two days after repotting, no improvement = poor prognosis.

Why It Failed

• Roots suffocated, rotted; can't uptake water → leaves droop.
• Summer droop is often heat/AC related, not thirst.

Last-Ditch Attempt

1. Unpot; wash roots; trim all brown/black mushy roots.
2. Dip in hydrogen peroxide (1:10) or cinnamon.
3. Repot in small pot with orchid bark/perlite/peat mix.
4. Bag loosely for humidity; bright indirect light.
5. Water only when top 1" dry.

Future Watering

• Thorough soak until drainage; wait until top 2" dry.
• Add 1 tsp Epsom salt/gallon monthly for magnesium.
• Never let sit in drainage water.

If no new growth in 3 weeks, replace.
