Dropping Leaves on rubber plant
What's Happening
Ficus elastica exhibits rapid leaf abscission as a survival mechanism when exposed to sudden environmental changes. When moved from high to low light, subjected to temperature fluctuations, or relocated to new environments, the plant activates pre-formed abscission layers at leaf bases. This stress response occurs within 24-72 hours and affects lower leaves first, progressing upward if stress persists. The mechanism is evolutionary adaptation to tropical understory conditions where rapid shedding conserves energy during unfavorable periods.
How to Fix It
- 1
Maintain stable location for minimum 2-4 weeks after any environmental change
- 2
Provide bright indirect light (2000-5000 lux) immediately to halt further drop
- 3
Avoid multiple changes simultaneously (light, humidity, temperature)
- 4
Gradually acclimate over 7-14 days when moving to permanent location
- 5
Expect 2-8 week recovery period; new growth emerges only from stem tips
How to Prevent It
Quarantine new plants for 14 days in stable environment before integrating into home. Gradual acclimation to light changes over 7-10 days. Maintain consistent 65-85°F temperatures and 40-60% humidity year-round.
