Ideal temperature for alocasia maharani (grey dragon)
Aim for 18-29°C (65-85°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
Alocasia Maharani (Grey Dragon) is frost-tender (USDA 10-11 (frost-tender; grown as a houseplant in cooler climates), 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 alocasia maharani (grey dragon)
Alocasia Maharani (Grey Dragon) sits happiest at around 60-80% relative humidity. A tropical plant that thrives in high humidity, ideally 60% or above. A humidifier is the most reliable way to provide it. Avoid heavy misting, as water sitting in the leaf crevices can encourage fungal disease; group with other plants or use a pebble tray instead. 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.
