Mass Cane (Corn Plant) Yellow/Brown Leaves: Root Rot from Overpotting

Root Cause

Soil staying wet for a month = pot too large, no drainage, dense soil, or light too low. Roots rot, causing yellow spots and brown leaves.

Diagnosis Checklist

• Did you repot into a larger pot?
• Does the pot have drainage holes?
• Is soil heavy/peaty without perlite?
• Is light very dim?

Fix

Address the specific cause. Trim brown leaf tips with scissors for appearance. Let soil dry more between waterings.
