Reviving a Droopy Peace Lily: Overwatering and Root Rot

A 10-year-old peace lily (Spathiphyllum) in a 12-inch plastic pot wouldn't perk up despite weekly gallon-watering and fertilizer. Owner feared it was dying.

Diagnosis: Overwatering and Root Rot

A gallon weekly in a 12-inch pot is excessive. Constant moisture rotted roots, so they can't absorb water—hence persistent droop.

Recovery Plan

1. Dry it out fast. No water until pot feels very light.
2. Drastically reduce water: Max 1.5 quarts, only when bone-dry.
3. Check weight before watering: Heavy = wet; light = ready.
4. Bright indirect light: Hand should cast a clear shadow, but no direct sun.
5. Winter: Water every 2 weeks, sparingly.
6. Never let sit in saucer water.

Expect Dieback

Much foliage may die and need trimming. But with patience and strict dryness, new healthy growth will return.
