Ideal temperature for laos lady palm

Aim for 15–28°C (59–82°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 15°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.

Cold tolerance & winter care

Laos Lady Palm is frost-tender (USDA 9b–11, 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 laos lady palm

Laos Lady Palm sits happiest at around 50–70% relative humidity. Appreciates moderate to high humidity. Leaf tips brown in dry air below 40%. Mist foliage occasionally, use a pebble tray with water, or run a humidifier nearby. Avoid placing near heating vents or air-conditioning units. 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.

Laos Lady Palm temperature & humidity — frequently asked questions

What temperature is best for laos lady palm?

Laos Lady Palm grows best between 15–28°C (59–82°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 laos lady palm tolerate?

Laos Lady Palm starts to suffer below roughly 15°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 laos lady palm need?

Laos Lady Palm prefers about 50–70% relative humidity. Appreciates moderate to high humidity. Leaf tips brown in dry air below 40%. Mist foliage occasionally, use a pebble tray with water, or run a humidifier nearby. Avoid placing near heating vents or air-conditioning units.

How do I raise humidity for laos lady palm?

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 laos lady palm live outside?

Laos Lady Palm is rated for USDA zone 9b–11 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.
