Cold Damage on parlor palm
What's Happening
Parlor palms are tropical plants native to the warm understory of Central American rainforests. They have minimal cold tolerance and suffer damage when temperatures drop below 50°F (10°C). Frost causes ice crystals to form within leaf cells, rupturing cell walls and creating characteristic brown, desiccated fronds. Cold damage is often mistaken for underwatering or disease, but the timing (after a cold snap) and the pattern (affecting outer fronds first) are diagnostic.
How to Fix It
- 1
Trim only fully brown, desiccated fronds at the base—leave partially green fronds for photosynthesis
- 2
Move plant to a warm location (65-75°F) with bright indirect light
- 3
Water sparingly during recovery to prevent root rot in weakened plant
- 4
Maintain humidity at 50-60% to support recovery
- 5
Monitor central growing point for 4-6 weeks—new growth indicates survival
- 6
If the central spear is mushy, the plant may not recover
How to Prevent It
Keep parlor palms indoors when temperatures drop below 55°F. Avoid placing near drafty windows in winter. Never leave outdoors unprotected in cold weather.
