Ideal temperature for jasmine (pink jasmine)
Temperature kills fewer jasmine (pink jasmine) 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 15-22C in active growth; 4-13C for 4-6 weeks in autumn to set flower buds (59-72F in active growth; 40-55F for 4-6 weeks in autumn to set buds) is fine; the spot you put the plant in matters more. Below roughly 15°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Jasmine (Pink Jasmine) is frost-tender (USDA USDA 9-11 (RHS hardiness H2; tender, minimum 1-5C / mid-30s to low-40s F). Grow indoors or under glass where frost occurs; can summer outdoors in mild, sheltered spots., 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 jasmine (pink jasmine)
Jasmine (Pink Jasmine) sits happiest at around 40-50% relative humidity. Prefers moderate to slightly elevated humidity. In dry, centrally heated rooms raise humidity with a pebble-and-water tray, a humidifier, or by grouping plants. Avoid placing it directly over hot radiators, which dry foliage and buds. 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.
Jasmine (Pink Jasmine) temperature & humidity — frequently asked questions
What temperature is best for jasmine (pink jasmine)?
Jasmine (Pink Jasmine) grows best between 15-22C in active growth; 4-13C for 4-6 weeks in autumn to set flower buds (59-72F in active growth; 40-55F for 4-6 weeks in autumn to set buds). 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 jasmine (pink jasmine) tolerate?
Jasmine (Pink Jasmine) 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 jasmine (pink jasmine) need?
Jasmine (Pink Jasmine) prefers about 40-50% relative humidity. Prefers moderate to slightly elevated humidity. In dry, centrally heated rooms raise humidity with a pebble-and-water tray, a humidifier, or by grouping plants. Avoid placing it directly over hot radiators, which dry foliage and buds.
How do I raise humidity for jasmine (pink jasmine)?
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 jasmine (pink jasmine) live outside?
Jasmine (Pink Jasmine) is rated for USDA zone USDA 9-11 (RHS hardiness H2; tender, minimum 1-5C / mid-30s to low-40s F). Grow indoors or under glass where frost occurs; can summer outdoors in mild, sheltered spots.. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
