Ideal temperature for microsorum pteropus 'windelov'
Microsorum pteropus 'Windelov' is comfortable in any room a person is comfortable in, roughly 20-28°C (68-82°F). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly 20°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Microsorum pteropus 'Windelov' is frost-tender (USDA Tropical aquarium fern; not frost-hardy (keep above 18°C), RHS H1a). 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 microsorum pteropus 'windelov'
Microsorum pteropus 'Windelov' sits happiest at around 100% (submerged) or near-saturated if emersed relative humidity. Grown submerged, humidity is irrelevant. If grown emersed in a paludarium or terrarium it needs near-saturated humidity to keep the fine frond tips from drying out. 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.
Microsorum pteropus 'Windelov' temperature & humidity — frequently asked questions
What temperature is best for microsorum pteropus 'windelov'?
Microsorum pteropus 'Windelov' grows best between 20-28°C (68-82°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 microsorum pteropus 'windelov' tolerate?
Microsorum pteropus 'Windelov' starts to suffer below roughly 20°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 microsorum pteropus 'windelov' need?
Microsorum pteropus 'Windelov' prefers about 100% (submerged) or near-saturated if emersed relative humidity. Grown submerged, humidity is irrelevant. If grown emersed in a paludarium or terrarium it needs near-saturated humidity to keep the fine frond tips from drying out.
How do I raise humidity for microsorum pteropus 'windelov'?
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 microsorum pteropus 'windelov' live outside?
Microsorum pteropus 'Windelov' is rated for USDA zone Tropical aquarium fern; not frost-hardy (keep above 18°C) and RHS hardiness H1a. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
