Ideal temperature for mignonette alpine strawberry
Mignonette Alpine Strawberry is comfortable in any room a person is comfortable in, roughly -30 to 28°C (-22 to 82°F). 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 -30°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Mignonette Alpine Strawberry is comparatively hardy (USDA 4-9, 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 mignonette alpine strawberry
Mignonette Alpine Strawberry sits happiest at around 40-70% relative humidity. An outdoor perennial of woodland margins, content in normal garden humidity and the cooler, slightly moist air of part shade. No special humidity control is needed when grown outside. 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.
