Ideal temperature for jelly palm
Temperature kills fewer jelly palm 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 -12 to 38°C (10 to 100°F) is fine; the spot you put the plant in matters more. Below roughly -12°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Jelly Palm is comparatively hardy (USDA 8a–11, RHS H3). 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 jelly palm
Jelly Palm sits happiest at around 40–70% relative humidity. Tolerates a broad range of humidity levels from subtropical to temperate. Not sensitive to the moderate humidity typical of UK gardens. Avoid siting in cold, damp hollows where frost pockets and high soil moisture combine. 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.
Jelly Palm temperature & humidity — frequently asked questions
What temperature is best for jelly palm?
Jelly Palm grows best between -12 to 38°C (10 to 100°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 jelly palm tolerate?
Jelly Palm starts to suffer below roughly -12°C. It tolerates a cold dormant period within USDA 8a–11, but a wet cold root zone is more dangerous than cold air.
What humidity does jelly palm need?
Jelly Palm prefers about 40–70% relative humidity. Tolerates a broad range of humidity levels from subtropical to temperate. Not sensitive to the moderate humidity typical of UK gardens. Avoid siting in cold, damp hollows where frost pockets and high soil moisture combine.
How do I raise humidity for jelly palm?
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 jelly palm live outside?
Jelly Palm is rated for USDA zone 8a–11 and RHS hardiness H3. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
