Ideal temperature for hoya polyneura (fishtail hoya)
Temperature kills fewer hoya polyneura (fishtail hoya) 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 10-25C (50-77F) is fine; the spot you put the plant in matters more. Below roughly 10°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Hoya polyneura (Fishtail Hoya) is frost-tender (USDA 10-11 (grown as an indoor houseplant in cooler climates), RHS undefined). 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 hoya polyneura (fishtail hoya)
Hoya polyneura (Fishtail Hoya) sits happiest at around 50% or higher relative humidity. Comes from monsoon-misted Himalayan forests and prefers steady moderate-to-high humidity, around 50% or more. It copes with average household air better than many thin-leaved hoyas, but a pebble tray, nearby plants or a humidifier helps in dry, heated rooms. Avoid prolonged spells below ~40% humidity. 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.
Hoya polyneura (Fishtail Hoya) temperature & humidity — frequently asked questions
What temperature is best for hoya polyneura (fishtail hoya)?
Hoya polyneura (Fishtail Hoya) grows best between 10-25C (50-77F). 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 hoya polyneura (fishtail hoya) tolerate?
Hoya polyneura (Fishtail Hoya) starts to suffer below roughly 10°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 hoya polyneura (fishtail hoya) need?
Hoya polyneura (Fishtail Hoya) prefers about 50% or higher relative humidity. Comes from monsoon-misted Himalayan forests and prefers steady moderate-to-high humidity, around 50% or more. It copes with average household air better than many thin-leaved hoyas, but a pebble tray, nearby plants or a humidifier helps in dry, heated rooms. Avoid prolonged spells below ~40% humidity.
How do I raise humidity for hoya polyneura (fishtail hoya)?
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 hoya polyneura (fishtail hoya) live outside?
Hoya polyneura (Fishtail Hoya) is rated for USDA zone 10-11 (grown as an indoor houseplant in cooler climates). Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
