Banana Plant in Pot: White Film, Brown Edges—Check Drainage and Pot Size

White film on banana leaves + brown edges on new growth in a covered lanai suggests:

• Standing water: If saucer holds water >15 min after watering, roots rot. Empty saucer or elevate pot.
• Low humidity: Mist leaves or group plants.
• Pot-bound: Bananas grow fast; may need larger pot.
• Cheap fertilizer: High salts burn edges. Use quality slow-release.
• Mosquitoes: Indicate wet soil/saucer.

Identify banana variety—some stay small, others huge.
