Leaf Drop on rubber plant
What's Happening
The most common cause of rubber plant decline is well-intentioned but excessive watering frequency. Ficus elastica originates from Southeast Asian tropical forests with distinct wet-dry seasons, developing thick storage roots and waxy cuticles for drought tolerance. When watered on fixed schedules (e.g., 'every Sunday') rather than soil dryness, roots remain chronically moist, leading to oxygen deprivation and eventual rot. The paradox: declining plants often receive MORE water when they actually need LESS.
How to Fix It
- 1
Switch to soil-based watering: Insert finger 3 inches deep—water only when completely dry
- 2
Lift pot test: Heavy pot indicates moisture retention; light pot signals readiness to water
- 3
Implement 'soak and dry' cycle: Thorough saturation followed by complete dry-out
- 4
Reduce frequency in winter: 3-4 weeks between waterings in low-growth periods
- 5
Use terracotta pots to accelerate soil drying through porous walls
How to Prevent It
Establish discipline of checking soil moisture before every watering. Never water based on calendar schedules. When uncertain, wait 3-5 additional days—rubber plants tolerate underwatering far better than overwatering.
