Ideal temperature for philodendron 'prince of orange'
Temperature kills fewer philodendron 'prince of orange' plants than you'd think. What kills them is the micro-climate within a normal-temperature room — a leaf pressed against single-glazed winter glass, the hot dry updraft directly above a radiator, the cold blast from an AC vent. The thermostat reading at 15-29C (60-85F) is fine; the spot you put the plant in matters more. Below roughly 15°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Philodendron 'Prince of Orange' is comparatively hardy (USDA 9-11 (grown as a houseplant elsewhere; not frost-hardy), RHS undefined). Within that range it tolerates a cold dormant spell outdoors; outside it, grow it in a container you can move under cover or overwinter in a cool but frost-free spot. Hardiness assumes an established plant in well-drained soil — a wet, cold root zone kills far more plants than cold air alone.
Humidity for philodendron 'prince of orange'
Philodendron 'Prince of Orange' sits happiest at around 50-70% relative humidity. As a tropical aroid it prefers moderate to high humidity (ideally 60-70%) but adapts to average home levels around 50%. Boost humidity with a humidifier or by grouping plants if leaf edges brown. 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.
Philodendron 'Prince of Orange' temperature & humidity — frequently asked questions
What temperature is best for philodendron 'prince of orange'?
Philodendron 'Prince of Orange' grows best between 15-29C (60-85F). 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 philodendron 'prince of orange' tolerate?
Philodendron 'Prince of Orange' starts to suffer below roughly 15°C. It tolerates a cold dormant period within USDA 9-11 (grown as a houseplant elsewhere; not frost-hardy), but a wet cold root zone is more dangerous than cold air.
What humidity does philodendron 'prince of orange' need?
Philodendron 'Prince of Orange' prefers about 50-70% relative humidity. As a tropical aroid it prefers moderate to high humidity (ideally 60-70%) but adapts to average home levels around 50%. Boost humidity with a humidifier or by grouping plants if leaf edges brown.
How do I raise humidity for philodendron 'prince of orange'?
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 philodendron 'prince of orange' live outside?
Philodendron 'Prince of Orange' is rated for USDA zone 9-11 (grown as a houseplant elsewhere; not frost-hardy). Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
