Ideal temperature for begonia 'picotee lace pink'
Temperature kills fewer begonia 'picotee lace pink' 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 13-24°C (frost-tender) (55-75°F (frost-tender)) is fine; the spot you put the plant in matters more. Below roughly 13°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Begonia 'Picotee Lace Pink' is frost-tender (USDA 9-11 outdoors; grown as an annual or lifted tuber in cooler zones, RHS H2 (frost-tender; lift and store tubers over winter)). 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 begonia 'picotee lace pink'
Begonia 'Picotee Lace Pink' sits happiest at around Average to moderately high (40-60%) relative humidity. Content in normal garden and patio humidity. Good airflow matters more than added humidity; crowded, damp, stagnant conditions promote powdery mildew and botrytis on the soft, double blooms. 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.
Begonia 'Picotee Lace Pink' temperature & humidity — frequently asked questions
What temperature is best for begonia 'picotee lace pink'?
Begonia 'Picotee Lace Pink' grows best between 13-24°C (frost-tender) (55-75°F (frost-tender)). 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 begonia 'picotee lace pink' tolerate?
Begonia 'Picotee Lace Pink' starts to suffer below roughly 13°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.

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 begonia 'picotee lace pink' live outside?
Begonia 'Picotee Lace Pink' is rated for USDA zone 9-11 outdoors; grown as an annual or lifted tuber in cooler zones and RHS hardiness H2 (frost-tender; lift and store tubers over winter).
