Ideal temperature for weeping blue atlas cedar
Temperature kills fewer weeping blue atlas cedar plants than you'd think. What kills them is the micro-climate within a normal-temperature room — a leaf pressed against single-glazed winter glass, the hot dry updraft directly above a radiator, the cold blast from an AC vent. The thermostat reading at -15 to 35°C (5 to 95°F) is fine; the spot you put the plant in matters more. Below roughly -15°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Weeping Blue Atlas Cedar is comparatively hardy (USDA 6-9, RHS H5). 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 weeping blue atlas cedar
Weeping Blue Atlas Cedar sits happiest at around Low to moderate (30–60%) relative humidity. Adapted to the semi-arid Atlas Mountain climate; tolerates low humidity well. Thrives in Mediterranean climates and warm-temperate regions. Excessive humidity combined with poor air movement can promote fungal issues. 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.
Weeping Blue Atlas Cedar temperature & humidity — frequently asked questions
What temperature is best for weeping blue atlas cedar?
Weeping Blue Atlas Cedar grows best between -15 to 35°C (5 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 weeping blue atlas cedar tolerate?
Weeping Blue Atlas Cedar starts to suffer below roughly -15°C. It tolerates a cold dormant period within USDA 6-9, but a wet cold root zone is more dangerous than cold air.
What humidity does weeping blue atlas cedar need?
Weeping Blue Atlas Cedar prefers about Low to moderate (30–60%) relative humidity. Adapted to the semi-arid Atlas Mountain climate; tolerates low humidity well. Thrives in Mediterranean climates and warm-temperate regions. Excessive humidity combined with poor air movement can promote fungal issues.
How do I raise humidity for weeping blue atlas cedar?
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 weeping blue atlas cedar live outside?
Weeping Blue Atlas Cedar is rated for USDA zone 6-9 and RHS hardiness H5. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
