Ideal temperature for chain pleurothallis
Temperature kills fewer chain pleurothallis plants than you'd think. What kills them is the micro-climate within a normal-temperature room — a leaf pressed against single-glazed winter glass, the hot dry updraft directly above a radiator, the cold blast from an AC vent. The thermostat reading at 8-24°C (ideal day 16-22°C, night 8-13°C) (46-75°F (ideal day 61-72°F, night 46-55°F)) is fine; the spot you put the plant in matters more. Below roughly 8°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Chain Pleurothallis is frost-tender (USDA 10-12 (container/indoor only), 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 chain pleurothallis
Chain Pleurothallis sits happiest at around 75-90% relative humidity. Very high humidity is essential. A cool-mist humidifier, enclosed plant case, or terrarium with ventilation works well. Always pair high humidity with adequate air movement to prevent Botrytis and crown rot. 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.
Chain Pleurothallis temperature & humidity — frequently asked questions
What temperature is best for chain pleurothallis?
Chain Pleurothallis grows best between 8-24°C (ideal day 16-22°C, night 8-13°C) (46-75°F (ideal day 61-72°F, night 46-55°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 chain pleurothallis tolerate?
Chain Pleurothallis starts to suffer below roughly 8°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 chain pleurothallis need?
Chain Pleurothallis prefers about 75-90% relative humidity. Very high humidity is essential. A cool-mist humidifier, enclosed plant case, or terrarium with ventilation works well. Always pair high humidity with adequate air movement to prevent Botrytis and crown rot.
How do I raise humidity for chain pleurothallis?
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 chain pleurothallis live outside?
Chain Pleurothallis is rated for USDA zone 10-12 (container/indoor only) 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.
