More about buchholz's tylecodon

Ideal temperature for buchholz's tylecodon

Buchholz's Tylecodon is comfortable in any room a person is comfortable in, roughly 10–30 °C (optimal); avoid below 2 °C (50–86 °F (optimal); avoid below 35 °F). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly 10°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.

Cold tolerance & winter care

Buchholz's Tylecodon is frost-tender (USDA 10b–11b, RHS H1c). 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 buchholz's tylecodon

Buchholz's Tylecodon sits happiest at around Under 50% RH; tolerates coastal fog but not stagnant humidity relative humidity. Adapted to dry coastal fog, not indoor humidity. Good air movement is essential. Avoid sealed terrariums or humid rooms. The difference between fog-moisture and ambient indoor humidity is significant — fog dries quickly on the plant surface. 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.

Buchholz's Tylecodon temperature & humidity — frequently asked questions

What temperature is best for buchholz's tylecodon?
