Diagnosing Yellow Leaves on Mass Cane (Corn Plant)

A mass cane plant from Walmart declined after months of health. Leaves yellowing; white worm-like critters found in soil (possibly dead). Owner considers repotting to replace soil.

Soil Critters Are a Distraction

Soil organisms indicate poor soil quality but don't cause yellowing. Repotting/replacing soil is drastic—like replacing all blood for an infection. Never warranted.

Real Causes: Light and Water

• Light: Best near uncovered north/east window or 4-6 feet from west/south window
• Water: If not repotted, remove loose surface soil. Water when top quarter of soil dries. Should reach that dryness in 1-2 weeks. Proper drying cycle is critical.

Yellowed leaves won't recover—remove them. Plant should gradually recover over a month with corrected conditions.
