Large Corn Plant Decline: Overwatering or Scale After Repotting

6-year-old corn plant repotted into larger pot, moved to brighter spot. Leaves yellowing, stems "strangled" look, some branches dying.

Two Likely Causes

1. Overwatering: New soil retains more moisture. Water only when dry; empty saucer. Repot only when root-bound, into slightly larger pot.
2. Scale insects: Small bumps on stems/leaves cause yellowing and stem shriveling.

Action

• Trim yellow/brown foliage.
• Spray Triple Action Plus (kills mites, insects, fungus) – can mix with horticultural oil.
• Reduce watering.
• Re-evaluate if no improvement.
