Why Is My Peace Lily Dying?

When a houseplant looks like it’s dying, you have about a week to diagnose correctly — here’s the triage order.

Quick answer

Step 1: pull it out of the pot. White roots = save it. Brown mushy roots = root rot, trim and repot in dry mix. Dry rootball = soak it.

Three things to check, in order

Cause 1

Root rot

Cause 2

Severe dehydration

Dry, crispy rootball that’s pulled away from the pot wall. Water runs through the cracks without absorbing.

Fix: Bottom-water in a saucer of room-temp water for 30 minutes. Repeat until rootball is fully rehydrated. Resume normal schedule.

Cause 3

Pest infestation past tolerance

Heavy spider mite, mealybug, or scale infestation can kill a plant if untreated for weeks.

Fix: If less than 30% of foliage is affected, treat with insecticidal soap + neem oil and quarantine. If more, throw it out and bag the soil to protect other plants.
