More about magdalene angraecum
Ideal temperature for magdalene angraecum
Magdalene Angraecum is comfortable in any room a person is comfortable in, roughly 14–24 °C (day 18–24 °C; night 14–18 °C; winter minimum ~8 °C briefly tolerated) (57–75 °F (day 64–75 °F; night 57–64 °F; brief dips to 46 °F tolerated when dry)). 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 14°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Magdalene Angraecum is frost-tender (USDA 10–12, 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 magdalene angraecum
Magdalene Angraecum sits happiest at around 60–80% relative humidity. Ideally 70–80% during active growth; can tolerate lower humidity (60%) during the cool, dry winter rest. Ensure good airflow at all times to prevent cold-season fungal issues. 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.
Magdalene Angraecum temperature & humidity — frequently asked questions
What temperature is best for magdalene angraecum?
Magdalene Angraecum grows best between 14–24 °C (day 18–24 °C; night 14–18 °C; winter minimum ~8 °C briefly tolerated) (57–75 °F (day 64–75 °F; night 57–64 °F; brief dips to 46 °F tolerated when dry)). 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 magdalene angraecum tolerate?
Magdalene Angraecum starts to suffer below roughly 14°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 magdalene angraecum need?
Magdalene Angraecum prefers about 60–80% relative humidity. Ideally 70–80% during active growth; can tolerate lower humidity (60%) during the cool, dry winter rest. Ensure good airflow at all times to prevent cold-season fungal issues.
How do I raise humidity for magdalene angraecum?
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 magdalene angraecum live outside?
Magdalene Angraecum is rated for USDA zone 10–12 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.
