Ideal temperature for apple 'gala'
Aim for -25 to 30°C tolerated; 15-24°C in growing season (-13 to 86°F tolerated; 59-75°F in growing season) 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 -25°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Apple 'Gala' is comparatively hardy (USDA 4-8 (outdoor; needs winter chill), RHS H6). 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 apple 'gala'
Apple 'Gala' sits happiest at around Ambient outdoor relative humidity. A hardy orchard tree with no humidity requirement. Damp, still conditions raise the risk of scab and mildew, so prioritise an open, sunny, airy position and good pruning. 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.
Apple 'Gala' temperature & humidity — frequently asked questions
What temperature is best for apple 'gala'?
Apple 'Gala' grows best between -25 to 30°C tolerated; 15-24°C in growing season (-13 to 86°F tolerated; 59-75°F in growing season). 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 apple 'gala' tolerate?
Apple 'Gala' starts to suffer below roughly -25°C. It tolerates a cold dormant period within USDA 4-8 (outdoor; needs winter chill), but a wet cold root zone is more dangerous than cold air.
What humidity does apple 'gala' need?
Apple 'Gala' prefers about Ambient outdoor relative humidity. A hardy orchard tree with no humidity requirement. Damp, still conditions raise the risk of scab and mildew, so prioritise an open, sunny, airy position and good pruning.
How do I raise humidity for apple 'gala'?
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 apple 'gala' live outside?
Apple 'Gala' is rated for USDA zone 4-8 (outdoor; needs winter chill) and RHS hardiness H6. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
