Ideal temperature for network calathea (calathea musaica)
Aim for 18-30°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
Network Calathea (Calathea Musaica) is frost-tender (USDA 10-11 (grown as a houseplant elsewhere; not frost hardy), 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 network calathea (calathea musaica)
Network Calathea (Calathea Musaica) sits happiest at around 50-80% relative humidity. A humidity-loving tropical that does best above 50%. In dry indoor air the leaf edges crisp and brown. Boost humidity with a pebble tray, a nearby humidifier, or grouping with other plants; a bathroom or kitchen with bright light suits it well. 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.
Network Calathea (Calathea Musaica) temperature & humidity — frequently asked questions
What temperature is best for network calathea (calathea musaica)?
Network Calathea (Calathea Musaica) grows best between 18-30°C (65-85°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 network calathea (calathea musaica) tolerate?
Network Calathea (Calathea Musaica) 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 network calathea (calathea musaica) need?
Network Calathea (Calathea Musaica) prefers about 50-80% relative humidity. A humidity-loving tropical that does best above 50%. In dry indoor air the leaf edges crisp and brown. Boost humidity with a pebble tray, a nearby humidifier, or grouping with other plants; a bathroom or kitchen with bright light suits it well.
How do I raise humidity for network calathea (calathea musaica)?
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 network calathea (calathea musaica) live outside?
Network Calathea (Calathea Musaica) is rated for USDA zone 10-11 (grown as a houseplant elsewhere; not frost hardy). Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
