Ideal temperature for golden delicious apple
Aim for -20 to 35°C (-4 to 95°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 -20°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Golden Delicious apple is comparatively hardy (USDA 5-8, 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 golden delicious apple
Golden Delicious apple sits happiest at around 35–65% relative humidity. Prefers moderate humidity. High humidity promotes russeting on the fruit skin (a cosmetic issue common with this cultivar) and increases scab pressure. In humid UK climates, fungicide programs and open pruning are important. 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.
Golden Delicious apple temperature & humidity — frequently asked questions
What temperature is best for golden delicious apple?
Golden Delicious apple grows best between -20 to 35°C (-4 to 95°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 golden delicious apple tolerate?
Golden Delicious apple starts to suffer below roughly -20°C. It tolerates a cold dormant period within USDA 5-8, but a wet cold root zone is more dangerous than cold air.
What humidity does golden delicious apple need?
Golden Delicious apple prefers about 35–65% relative humidity. Prefers moderate humidity. High humidity promotes russeting on the fruit skin (a cosmetic issue common with this cultivar) and increases scab pressure. In humid UK climates, fungicide programs and open pruning are important.
How do I raise humidity for golden delicious apple?
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 golden delicious apple live outside?
Golden Delicious apple is rated for USDA zone 5-8 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.
