How Cold Can Pothos Tolerate? Ultimate Guide

By Marcus Williams · January 23, 2026

Golden pothos (Epipremnum aureum) can typically tolerate brief exposure to temperatures as low as 50°F (10°C), but prolonged cold below this threshold causes irreversible damage. Frost is fatal.

Understanding Pothos Cold Tolerance

Pothos, a tropical vine native to Southeast Asia and the Pacific Islands, thrives in warm, humid environments. While it's one of the most resilient houseplants, its cold sensitivity stems from its evolutionary adaptation to consistently warm climates. Exposure to cold temperatures disrupts cellular function, leading to chilling injury, leaf drop, and root damage.

Key Signs of Cold Stress in Pothos

Wilting or drooping leaves despite moist soil
Blackened or mushy stems and leaves
Yellowing foliage unrelated to watering
Stunted growth or complete growth halt
Foul odor indicating root rot from cold-damp conditions

Optimal Temperature Range for Pothos Health

For peak performance, maintain daytime temperatures between 70–90°F (21–32°C) and nighttime lows no lower than 60°F (15.5°C). Sudden temperature drops—even within these ranges—can stress the plant if they occur rapidly.

Indoor vs. Outdoor Growing Considerations

Indoors, pothos adapts well to standard home temperatures. Outdoors, it's best suited to USDA zones 10–12. In temperate regions, it should be grown in containers and brought inside before fall temperatures dip below 55°F.

Temperature (°F)	Temperature (°C)	Effect on Pothos	Duration Tolerance
90–100	32–38	Heat stress; increased transpiration	Short-term (hours)
70–90	21–32	Optimal growth range	Unlimited
60–69	15.5–20.5	Slowed metabolism; reduced growth	Days to weeks
50–59	10–15	Chilling injury risk; cell membrane damage	Hours (avoid prolonged)
32–49	0–9	Frost-freeze damage; tissue death	Minutes to hours (fatal)
<32	<0	Instant freezing; plant death	Immediate

Table data source:1, 2, 3

The data confirms that pothos begins experiencing physiological stress below 60°F, with significant risk emerging at 50°F. Temperatures near freezing cause rapid cellular breakdown due to ice crystal formation. Even short exposure during transport or near drafty windows can trigger decline.

Protecting Pothos from Cold Damage

Winter Indoor Care Tips

Avoid placing pothos near drafty windows, doors, or air conditioning vents
Maintain consistent room temperature above 60°F
Use thermal curtains to buffer window cold at night
Group plants together to create a microclimate with higher humidity

Safely Moving Pothos Indoors and Outdoors

Begin transitioning pothos indoors when nighttime temperatures consistently fall below 55°F. Wait until all frost danger has passed and nighttime temps stay above 60°F before moving back outside in spring. Acclimate gradually over 7–10 days to prevent shock.

Recovering a Cold-Damaged Pothos

If your pothos suffers cold exposure:

Move immediately to a warm, stable environment (70–75°F)
Cut away blackened or mushy stems with sterilized pruners
Reduce watering until new growth appears
Provide bright, indirect light—no direct sun
Wait 2–4 weeks for recovery signs; new shoots indicate survival

Note: Do not fertilize until full recovery, as this stresses weakened roots.

About Pothos Cold Tolerance: Common Questions

Can pothos survive 40°F?

No, pothos cannot survive 40°F (4.4°C). At this temperature, ice forms in plant tissues, causing irreversible cell rupture and death. Even a few hours at 40°F can kill the plant.

Will pothos come back after freezing?

Generally, no. If the main stem and root system have frozen, recovery is unlikely. However, if only outer vines were damaged and the base remains firm and green, trim the dead parts and wait for regrowth from healthy nodes.

Is 55°F too cold for pothos?

55°F (12.8°C) is below ideal but may be tolerated briefly. Prolonged exposure slows growth and increases disease susceptibility. For long-term health, keep above 60°F.

Can I leave my pothos outside in winter?

Only in USDA zones 10–12 where temperatures never drop below 50°F. In colder zones, bring pothos indoors before fall frosts. Outdoor exposure to cold rain and wind accelerates chilling injury.

How do I protect pothos during cold transport?

Wrap the plant in insulating material like bubble wrap or a moving blanket. Avoid leaving it in a cold car overnight. Transport during daylight hours when temperatures are highest, and acclimate indoors away from drafts before unwrapping.
