Peace Lily Yellow Leaves: The Overwatering Connection

Three peace lilies (Spathiphyllum) developing yellow-marble leaves that turn brown and dry indicate chronic overwatering. Even with filtered light and fertilizer sticks, constantly wet soil suffocates roots, causing rot and yellowing.

Correct Watering Routine

1. Water thoroughly until moisture reaches drain tray.
2. Empty drain tray after one hour—never let plants sit in water.
3. Wait until top soil feels very dry and pot feels light before watering again.
4. Allow a 2-day dry period between waterings for root aeration.

Peace lilies prefer to dry slightly between waterings. The "wet-dry" cycle lets roots breathe, preventing rot. New green leaves will emerge once the cycle is established.
