Diagnosing Brown Leaves on Massangeana Cane (Corn Plant)

A 3-year-old Massangeana Cane has many leaves turning brown. Owner wonders about repotting or fertilizing.

Light or water issues are the primary causes. A photo of the whole plant helps diagnosis.
Normal aging: Some lower leaf browning is expected.
New leaf discoloration: Indicates watering problem.
Repotting: Rarely needed. Only if roots circle drainage holes and mass at bottom; then trim roots and add soil to bottom of same pot.
Fertilizer: Won't help; excess causes more browning.
Water quality: If tap water is hard, use filtered, distilled, or rainwater.
Watering rule: Water when top quarter of soil feels dry.
Light: Very bright, indirect light is best.
