Troubleshooting Brown Tips on Peace Lily

Checklist of Causes

1. Hard water: Switch to filtered/distilled/rain water.
2. Soil too dry: Water when surface barely dry/just before wilting.
3. Soil too wet: Let top inch dry between waterings.
4. Low light: Bright indirect (north windowsill or under fluorescents).
5. Over-fertilizing: Half-strength, only during vigorous growth.

Repotting Warning

Repotting unless severely rootbound increases root rot risk and reduces flowering. Your repotting may be part of the problem.

Action

Address the applicable factors above. Trim brown tips (they won't heal).
