Ideal temperature for coppertone stonecrop
Aim for 18-27 C (65-80 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 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Coppertone Stonecrop is frost-tender (USDA USDA zones 10-11 (hardy to about 30 F / -1 C); not frost-tolerant, grow as a houseplant or overwinter indoors in colder zones., RHS undefined). 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 coppertone stonecrop
Coppertone Stonecrop sits happiest at around Low (around 30-50%) relative humidity. A dry-tolerant succulent that prefers low ambient humidity and good airflow. No misting needed; high humidity with poor ventilation invites rot. 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.
Coppertone Stonecrop temperature & humidity — frequently asked questions
What temperature is best for coppertone stonecrop?
Coppertone Stonecrop 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 coppertone stonecrop tolerate?
Coppertone Stonecrop 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 coppertone stonecrop need?
Coppertone Stonecrop prefers about Low (around 30-50%) relative humidity. A dry-tolerant succulent that prefers low ambient humidity and good airflow. No misting needed; high humidity with poor ventilation invites rot.
How do I raise humidity for coppertone stonecrop?
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 coppertone stonecrop live outside?
Coppertone Stonecrop is rated for USDA zone USDA zones 10-11 (hardy to about 30 F / -1 C); not frost-tolerant, grow as a houseplant or overwinter indoors in colder zones.. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
