Ideal temperature for pelargonium 'lemon fancy'
Aim for 10-24°C (50-75°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 10°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Pelargonium 'Lemon Fancy' is frost-tender (USDA 9-11 (frost-tender; overwinter under cover or grow as an annual in colder regions), RHS H2). 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 pelargonium 'lemon fancy'
Pelargonium 'Lemon Fancy' sits happiest at around 40-55% relative humidity. Prefers average, on-the-dry-side household air and good airflow. Humid, stagnant conditions encourage grey mould on the foliage; no misting required. 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.

What temperature is best for pelargonium 'lemon fancy'?
Pelargonium 'Lemon Fancy' grows best between 10-24°C (50-75°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 pelargonium 'lemon fancy' tolerate?

What humidity does pelargonium 'lemon fancy' need?

Pelargonium 'Lemon Fancy' is rated for USDA zone 9-11 (frost-tender; overwinter under cover or grow as an annual in colder regions) and RHS hardiness H2. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
