Ideal temperature for philodendron 'florida green'
Temperature kills fewer philodendron 'florida green' 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 18-29 C (64-84 F) is fine; the spot you put the plant in matters more. Below roughly 18°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Philodendron 'Florida Green' is comparatively hardy (USDA USDA 9b-11 outdoors; 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 green'
Philodendron 'Florida Green' sits happiest at around 50-70% relative humidity. Comfortable in average household humidity but rewards higher levels with larger, more lobed leaves. Aim for 50-70%; group plants or run a humidifier in dry rooms. Light and root health drive growth more than humidity, so do not over-rely on misting. 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 Green' temperature & humidity — frequently asked questions
What temperature is best for philodendron 'florida green'?
Philodendron 'Florida Green' grows best between 18-29 C (64-84 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 green' tolerate?
Philodendron 'Florida Green' starts to suffer below roughly 18°C. It tolerates a cold dormant period within USDA USDA 9b-11 outdoors; grown as a houseplant elsewhere, but a wet cold root zone is more dangerous than cold air.
What humidity does philodendron 'florida green' need?
Philodendron 'Florida Green' prefers about 50-70% relative humidity. Comfortable in average household humidity but rewards higher levels with larger, more lobed leaves. Aim for 50-70%; group plants or run a humidifier in dry rooms. Light and root health drive growth more than humidity, so do not over-rely on misting.
How do I raise humidity for philodendron 'florida green'?
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 green' live outside?
Philodendron 'Florida Green' is rated for USDA zone USDA 9b-11 outdoors; 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.
