Ideal temperature for hardy chinese windmill palm
Aim for -12 to 27°C (10-80°F) on the thermostat and you've handled the easy part. The hard part is the half-metre around the plant: window glass that drops to near-freezing on a January night, a radiator pumping out hot dry air, a draught from an opened front door. Move the plant 30 cm and you've usually fixed the problem. Below roughly -12°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Hardy Chinese Windmill Palm is comparatively hardy (USDA 7b-11 (established plants tolerate roughly -12 to -15°C), RHS H5). Within that range it tolerates a cold dormant spell outdoors; outside it, grow it in a container you can move under cover or overwinter in a cool but frost-free spot. Hardiness assumes an established plant in well-drained soil — a wet, cold root zone kills far more plants than cold air alone.
Humidity for hardy chinese windmill palm
Hardy Chinese Windmill Palm sits happiest at around Ambient outdoor humidity relative humidity. Unfussy about humidity as a garden palm and copes with damp temperate climates. Indoors it prefers average to slightly raised humidity and good air movement. 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.

How cold can hardy chinese windmill palm tolerate?
Hardy Chinese Windmill Palm starts to suffer below roughly -12°C. It tolerates a cold dormant period within USDA 7b-11 (established plants tolerate roughly -12 to -15°C), but a wet cold root zone is more dangerous than cold air.
