Ideal temperature for echeveria 'ice green'
Temperature kills fewer echeveria 'ice green' 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 18-27°C (65-80°F) is fine; the spot you put the plant in matters more. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Echeveria 'Ice Green' is frost-tender (USDA 9-11 (indoor or frost-free patio 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 echeveria 'ice green'
Echeveria 'Ice Green' sits happiest at around 30-50% relative humidity. Prefers dry to average household air. High humidity with poor airflow encourages fungal rot and spoils the farina, so good ventilation matters more than any added moisture. 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.
Echeveria 'Ice Green' temperature & humidity — frequently asked questions
What temperature is best for echeveria 'ice green'?
Echeveria 'Ice Green' grows best between 18-27°C (65-80°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 echeveria 'ice green' tolerate?
Echeveria 'Ice Green' starts to suffer below roughly 18°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 echeveria 'ice green' need?
Echeveria 'Ice Green' prefers about 30-50% relative humidity. Prefers dry to average household air. High humidity with poor airflow encourages fungal rot and spoils the farina, so good ventilation matters more than any added moisture.
How do I raise humidity for echeveria 'ice green'?
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 echeveria 'ice green' live outside?
Echeveria 'Ice Green' is rated for USDA zone 9-11 (indoor or frost-free patio 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.
