More about common pothos
Ideal temperature for common pothos
Common Pothos is comfortable in any room a person is comfortable in, roughly 18-28°C (65-82°F). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Common Pothos is frost-tender (USDA 10-12 (indoor-only outside tropical climates), RHS H1b). It cannot survive a frost, so in most of the US and UK it lives indoors year-round or summers outside and comes back in well before the first autumn frost — once nights drop toward 10-12°C is the cue, not the first frost warning. Acclimate it over a week when moving between indoors and out so the leaves do not shock.
Humidity for common pothos
Common Pothos sits happiest at around 50-70% relative humidity. Prefers moderate to high humidity; tolerates typical household levels of 40-50% but may show brown leaf tips below this. A pebble tray or occasional grouping with other plants is sufficient in most homes. The usual low-humidity tell is crisp brown leaf tips and edges while the soil moisture is fine — a sign the air, not the watering, is the problem. If you need to raise it, the reliable methods are grouping plants together, standing the pot on a tray of damp pebbles (the pot above the waterline, never in it), or running a small humidifier in winter when indoor heating dries the air most. Misting is the least effective — it raises humidity for minutes, not hours.
Common Pothos temperature & humidity — frequently asked questions
What temperature is best for common pothos?
Common Pothos grows best between 18-28°C (65-82°F). Keep it out of cold draughts, off freezing windowsills in winter, and away from the hot dry air directly above radiators — the extremes matter far more than the average room temperature.
How cold can common pothos tolerate?
Common Pothos starts to suffer below roughly 18°C. It is frost-tender and will be damaged or killed by a frost, so bring it indoors once nights fall toward 10-12°C.
What humidity does common pothos need?
Common Pothos prefers about 50-70% relative humidity. Prefers moderate to high humidity; tolerates typical household levels of 40-50% but may show brown leaf tips below this. A pebble tray or occasional grouping with other plants is sufficient in most homes.
How do I raise humidity for common pothos?
Group it with other plants, stand the pot on a tray of damp pebbles (kept above the waterline), or run a small humidifier in winter. Misting only helps for a few minutes, so it is the weakest option for a plant that genuinely needs more humidity.
Can common pothos live outside?
Common Pothos is rated for USDA zone 10-12 (indoor-only outside tropical climates) and RHS hardiness H1b. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
