Ideal temperature for cotyledon eliseae
Cotyledon Eliseae is comfortable in any room a person is comfortable in, roughly 10-27°C (50-80°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
Cotyledon Eliseae is frost-tender (USDA 9-11 (indoor or frost-free in most US homes), 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 cotyledon eliseae
Cotyledon Eliseae sits happiest at around 30-50% relative humidity. Prefers average to dry household humidity and needs no misting. High humidity and poor airflow encourage fungal problems and spoil the farina, so favour good ventilation. 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.
Cotyledon Eliseae temperature & humidity — frequently asked questions
What temperature is best for cotyledon eliseae?
Cotyledon Eliseae grows best between 10-27°C (50-80°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 cotyledon eliseae tolerate?
Cotyledon Eliseae starts to suffer below roughly 10°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.
What humidity does cotyledon eliseae need?
Cotyledon Eliseae prefers about 30-50% relative humidity. Prefers average to dry household humidity and needs no misting. High humidity and poor airflow encourage fungal problems and spoil the farina, so favour good ventilation.
How do I raise humidity for cotyledon eliseae?
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 cotyledon eliseae live outside?
Cotyledon Eliseae is rated for USDA zone 9-11 (indoor or frost-free in most US homes) 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.
