cold damage on Pothos
Quick answer
If your Pothos has cold damage, the most likely cause is: Cold shock in Epipremnum aureum (pothos) occurs when ambient temperature drops below 50°F (10°C) for more than 2-4 hours, causing ice crystal formation within cell walls that ruptures thin tropical leaf tissue. Unlike temperate plants with dormancy mechanisms, pothos lacks antifreeze proteins and cannot enter protective dormancy — cellular damage is immediate and irreversible in affected tissues. The vining habit allows regrowth from undamaged nodes if vascular cambium survives.
Start here:
- 1. 1. Immediate relocation: Move plant to warm location (65-80°F / 18-27°C) away from cold drafts immediately upon discovering exposure.
- 2. 2. Assess damage: Check stems for firmness — green and flexible indicates living tissue; black, mushy, or wilted stems indicate kill.
Why Pothos gets cold damage
Epipremnum aureum
Cold shock in Epipremnum aureum (pothos) occurs when ambient temperature drops below 50°F (10°C) for more than 2-4 hours, causing ice crystal formation within cell walls that ruptures thin tropical leaf tissue. Unlike temperate plants with dormancy mechanisms, pothos lacks antifreeze proteins and cannot enter protective dormancy — cellular damage is immediate and irreversible in affected tissues.

How to reverse cold damage on Pothos
- 1
1. Immediate relocation: Move plant to warm location (65-80°F / 18-27°C) away from cold drafts immediately upon discovering exposure.

2. Assess damage: Check stems for firmness — green and flexible indicates living tissue; black, mushy, or wilted stems indicate kill.
- 3
3. Prune dead tissue: Remove all blackened, wilted, or crispy leaves with sterilized scissors, cutting back to healthy tissue.

4. Reduce watering by 50%: Cold-stressed roots have reduced uptake capacity; allow top 2-3 inches of soil to dry before watering.
- 5
5. Provide bright indirect light: Position in 1000-2000 lux to support recovery photosynthesis without phototoxic stress.
- 6
6. Monitor for 2-4 weeks: New growth from nodes indicates recovery; if no new growth after 4 weeks, propagate from healthy cuttings.
- 7
7. Recovery propagation: If no sign of recovery after 4 weeks, take 4-6 inch cuttings from healthy vines, remove bottom leaves, place in water to root.
Keep cold damage off this Pothos
Maintain minimum ambient temperature of 55°F (13°C) year-round; position plants away from windows, exterior doors, and HVAC vents during cold months; use smart thermostat alerts for temperature drops; avoid placing pothos in rooms with poor insulation or where cold drafts occur.
