More about calathea network gold

Ideal temperature for calathea network gold

Aim for 18-27°C (65-80°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

Calathea Network Gold is frost-tender (USDA 11-12 (grown indoors in most US homes), 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 network gold

Calathea Network Gold sits happiest at around 60-70% relative humidity. High humidity keeps the network crisp; below 50% the fine markings dull and edges brown. A humidifier, pebble tray, or grouping with other plants helps. Keep it away from radiators 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 Network Gold temperature & humidity — frequently asked questions

What temperature is best for calathea network gold?

Calathea Network Gold 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 network gold tolerate?

Calathea Network Gold 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 calathea network gold need?

Calathea Network Gold prefers about 60-70% relative humidity. High humidity keeps the network crisp; below 50% the fine markings dull and edges brown. A humidifier, pebble tray, or grouping with other plants helps. Keep it away from radiators and cold draughts.

How do I raise humidity for calathea network gold?

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 calathea network gold live outside?

Calathea Network Gold is rated for USDA zone 11-12 (grown indoors in most US homes) and RHS hardiness H1b. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
