Ideal temperature for philodendron 'florida ghost'
Philodendron 'Florida Ghost' is comfortable in any room a person is comfortable in, roughly 18-29°C (65-85°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 18°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Philodendron 'Florida Ghost' is comparatively hardy (USDA 9-11 (grown as a houseplant elsewhere), 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 'florida ghost'
Philodendron 'Florida Ghost' sits happiest at around 60-80% preferred; tolerates 45%+ relative humidity. Thrives in above-average humidity; higher levels (60-80%) encourage larger, well-formed leaves. It survives at average household humidity (around 45-50%) but very dry air can cause deformed new growth and brown leaf edges. Group plants, use a pebble tray, or run a humidifier to raise local humidity. 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 'Florida Ghost' temperature & humidity — frequently asked questions
What temperature is best for philodendron 'florida ghost'?
Philodendron 'Florida Ghost' grows best between 18-29°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 philodendron 'florida ghost' tolerate?
Philodendron 'Florida Ghost' starts to suffer below roughly 18°C. It tolerates a cold dormant period within USDA 9-11 (grown as a houseplant elsewhere), but a wet cold root zone is more dangerous than cold air.
What humidity does philodendron 'florida ghost' need?
Philodendron 'Florida Ghost' prefers about 60-80% preferred; tolerates 45%+ relative humidity. Thrives in above-average humidity; higher levels (60-80%) encourage larger, well-formed leaves. It survives at average household humidity (around 45-50%) but very dry air can cause deformed new growth and brown leaf edges. Group plants, use a pebble tray, or run a humidifier to raise local humidity.
How do I raise humidity for philodendron 'florida ghost'?
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 'florida ghost' live outside?
Philodendron 'Florida Ghost' is rated for USDA zone 9-11 (grown as a houseplant elsewhere). Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
