Ideal temperature for singapore yellow frangipani
Singapore Yellow Frangipani is comfortable in any room a person is comfortable in, roughly 15–38 °C (59–100 °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 15°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Singapore Yellow Frangipani 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 singapore yellow frangipani
Singapore Yellow Frangipani sits happiest at around 40–70% relative humidity. Naturally from humid tropical regions and tolerates high humidity well; moderate household humidity is equally acceptable. Prioritise good air circulation to prevent frangipani rust and other fungal problems. Avoid misting the foliage directly. 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.
Singapore Yellow Frangipani temperature & humidity — frequently asked questions
What temperature is best for singapore yellow frangipani?
Singapore Yellow Frangipani grows best between 15–38 °C (59–100 °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 singapore yellow frangipani tolerate?
Singapore Yellow Frangipani starts to suffer below roughly 15°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 singapore yellow frangipani need?
Singapore Yellow Frangipani prefers about 40–70% relative humidity. Naturally from humid tropical regions and tolerates high humidity well; moderate household humidity is equally acceptable.
