Cold Damage on rubber plant
What's Happening
Ficus elastica is tropical in origin and suffers chilling injury when exposed to temperatures below 55°F (13°C). Cold damage manifests as blackened, water-soaked patches on leaves, wilting, and rapid leaf drop. Unlike sunburn (which affects exposed surfaces), cold damage often appears uniformly or on leaves closest to cold sources. Drafts from windows, air conditioning vents, or winter transport from stores are common causes. Recovery is slow as cellular damage is permanent.
How to Fix It
- 1
Move plant immediately to stable 65-75°F location away from drafts
- 2
Remove severely damaged leaves to prevent secondary infection
- 3
Do NOT fertilize or repot until plant shows new growth—additional stress impairs recovery
- 4
Increase humidity to 60%+ to support stressed tissue
- 5
Expect 6-12 week recovery period; monitor for new growth as recovery signal
How to Prevent It
Maintain minimum 60°F year-round. Never place near drafty windows in winter. Avoid locations near AC vents. When purchasing in cold months, wrap plant thoroughly for transport and minimize outdoor exposure.
