Ideal temperature for begonia × tuberhybrida 'non-stop mocca white'
Aim for 13-24°C (55-75°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 13°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Begonia × tuberhybrida 'Non-Stop Mocca White' is frost-tender (USDA 9-11 (tubers lifted and stored frost-free elsewhere; grown as an annual), 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 begonia × tuberhybrida 'non-stop mocca white'
Begonia × tuberhybrida 'Non-Stop Mocca White' sits happiest at around 40-60% relative humidity. Tolerates average room and garden humidity. Good air circulation matters more than high humidity here, as still, damp air encourages powdery mildew and botrytis on the 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.
