Plant + symptom guide

Peace Lily yellow leaves

Yellow leaves are a pattern, not a diagnosis. On this plant, read them against soil moisture, light level, leaf age, drainage, and recent care changes.

For peace lily, adjust the diagnosis around this plant profile: Peace lilies wilt dramatically, so the key is separating dry-soil droop from wet-soil root stress. Brown tips are common and should be read with watering and humidity.

How to confirm it

Check whether yellowing starts on old lower leaves or appears across new growth too.

Feel the soil below the surface before watering again.

Look for a recent move, seasonal light drop, or a pot that stays wet.

Lift the pot before watering because peace lilies droop from both dry and wet soil.

Check whether brown tips are old cosmetic damage or paired with yellowing.
