Ideal temperature for egremont russet apple
Egremont Russet Apple is comfortable in any room a person is comfortable in, roughly -20 to 30°C (fully hardy; needs winter chill to fruit) (-4 to 86°F (fully hardy; needs winter chill to fruit)). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly -20°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Egremont Russet Apple is comparatively hardy (USDA 4-8 (outdoor orchard tree), 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 egremont russet apple
Egremont Russet Apple sits happiest at around Outdoor ambient relative humidity. An outdoor hardy tree with no humidity requirement; it actually shows good resistance to scab in damp climates. Good airflow through the canopy via pruning reduces fungal disease in wet seasons. 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.
