The most common terminal diagnosis. Brown, mushy, smelly roots can’t absorb water. Plant droops despite wet soil. Trim every soft root with sterile scissors. Repot in fresh dry potting mix with extra perlite. Water sparingly until new white roots appear.

Dry, crispy rootball that’s pulled away from the pot wall. Water runs through the cracks without absorbing. Bottom-water in a saucer of room-temp water for 30 minutes. Repeat until rootball is fully rehydrated. Resume normal schedule.

Why Is My Monstera 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

The most common terminal diagnosis. Brown, mushy, smelly roots can’t absorb water. Plant droops despite wet soil.

Fix: Trim every soft root with sterile scissors. Repot in fresh dry potting mix with extra perlite. Water sparingly until new white roots appear.

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.
