More about shingle plant
Ideal temperature for shingle plant
Aim for 18-29C (65-85F) 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
Shingle Plant is frost-tender (USDA 10-12 (outdoors); grown as a houseplant elsewhere, 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 shingle plant
Shingle Plant sits happiest at around 60-80% relative humidity. A true high-humidity plant. It thrives at 60% and above; growth slows or stalls when humidity drops much below 50-60%. Group with other plants, run a humidifier, or grow in a more enclosed space. A damp moss pole helps keep aerial roots and new leaves shingling tightly. 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.
Shingle Plant temperature & humidity — frequently asked questions
What temperature is best for shingle plant?
Shingle Plant grows best between 18-29C (65-85F). 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 shingle plant tolerate?
Shingle Plant 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 shingle plant need?
Shingle Plant prefers about 60-80% relative humidity. A true high-humidity plant. It thrives at 60% and above; growth slows or stalls when humidity drops much below 50-60%. Group with other plants, run a humidifier, or grow in a more enclosed space. A damp moss pole helps keep aerial roots and new leaves shingling tightly.
How do I raise humidity for shingle plant?
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 shingle plant live outside?
Shingle Plant is rated for USDA zone 10-12 (outdoors); grown as a houseplant elsewhere. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
