Ideal temperature for cherapu
Temperature kills fewer cherapu 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 21–35°C (70–95°F) is fine; the spot you put the plant in matters more. Below roughly 21°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Cherapu is frost-tender (USDA 10b–12, RHS H1a). 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 cherapu
Cherapu sits happiest at around 70–95% relative humidity. Requires high humidity typical of Peninsular Malaysian lowland forest. In cultivation outside the tropics, grow in a heated greenhouse or mist daily. Low humidity causes bud and flower drop, preventing fruiting. 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.
Cherapu temperature & humidity — frequently asked questions
What temperature is best for cherapu?
Cherapu grows best between 21–35°C (70–95°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 cherapu tolerate?
Cherapu starts to suffer below roughly 21°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 cherapu need?
Cherapu prefers about 70–95% relative humidity. Requires high humidity typical of Peninsular Malaysian lowland forest. In cultivation outside the tropics, grow in a heated greenhouse or mist daily. Low humidity causes bud and flower drop, preventing fruiting.
How do I raise humidity for cherapu?
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 cherapu live outside?
Cherapu is rated for USDA zone 10b–12 and RHS hardiness H1a. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
