Root Rot in Mature Mass Cane: Emergency Drying Protocol

Vinny's 20-year-old, 8-foot mass cane suddenly smelled like sour rotting garbage. Mushrooms grew at the base and in the soil.

Diagnosis: Root Rot from Overwatering

The smell and mushrooms confirm rotting roots and soil. The plant is sitting in a "swamp."

Immediate Steps

1. Empty the drain tray NOW.
2. Dry out aggressively: Place pot in bathtub without tray for 24 hours to maximize drainage.
3. No water for 3–4 weeks – let soil become very dry.
4. Winter care: Water only every 2 weeks, small amounts, until spring.

Mass canes hate wet feet. Short days mean less water use. Dry conditions now can save this longtime companion.
