Ideal temperature for calathea louisae 'maui queen'
Temperature kills fewer calathea louisae 'maui queen' 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
Calathea Louisae 'Maui Queen' is frost-tender (USDA 11-12 (grown as a houseplant in most of the US), RHS H1b). 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 calathea louisae 'maui queen'
Calathea Louisae 'Maui Queen' sits happiest at around 60-70%+ relative humidity. Requires high humidity; below about 50% the leaf margins crisp and brown. A humidifier gives the most consistent results, supported by pebble trays and grouping with other plants. Keep it away from radiators, vents and cold draughts. 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.

Calathea Louisae 'Maui Queen' 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 calathea louisae 'maui queen' tolerate?

How do I raise humidity for calathea louisae 'maui queen'?
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.
