Diagnosing Total Leaf Browning in Indoor Palms: Overwatering and Fertilizer Issues

Watering 3×/Week Is Drowning the Roots

A 5.5-foot indoor palm with all leaves (including center) turning brown, fungus on soil, and herb fertilizer used: classic overwatering + wrong fertilizer.

Corrections

• Water once a week or when dry halfway down.
• Mist fronds frequently.
• Use granular palm fertilizer every 3 months.
• Stop herb fertilizer—it's wrong formulation.

Root Recovery

Let soil dry. If roots aren't rotted, new growth appears in weeks. Fungus on soil surface confirms excess moisture.
