More about ice cream banana
Ideal temperature for ice cream banana
Aim for 18-30°C (65-86°F) on the thermostat and you've handled the easy part. The hard part is the half-metre around the plant: window glass that drops to near-freezing on a January night, a radiator pumping out hot dry air, a draught from an opened front door. Move the plant 30 cm and you've usually fixed the problem. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Ice Cream Banana is frost-tender (USDA 8-11 outdoors (more cold-hardy than Cavendish); container/indoor in cooler zones, RHS H2). 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 ice cream banana
Ice Cream Banana sits happiest at around 50-70% relative humidity. Likes moderate to high humidity for lush foliage but tolerates breezier sites well. Dry indoor air browns leaf edges and encourages spider mites. 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.
Ice Cream Banana temperature & humidity — frequently asked questions
What temperature is best for ice cream banana?
Ice Cream Banana grows best between 18-30°C (65-86°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 ice cream banana tolerate?
Ice Cream Banana starts to suffer below roughly 18°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 ice cream banana need?
Ice Cream Banana prefers about 50-70% relative humidity. Likes moderate to high humidity for lush foliage but tolerates breezier sites well. Dry indoor air browns leaf edges and encourages spider mites.
How do I raise humidity for ice cream banana?
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 ice cream banana live outside?
Ice Cream Banana is rated for USDA zone 8-11 outdoors (more cold-hardy than Cavendish); container/indoor in cooler zones and RHS hardiness H2. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
