Ideal temperature for european cypress (goldcrest lemon cypress)
Aim for 13-18°C (55-65°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 13°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
European Cypress (Goldcrest Lemon Cypress) is comparatively hardy (USDA USDA 7a-10b (outdoors), RHS RHS H4 (hardy to about -10°C); holds the RHS Award of Garden Merit). 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 european cypress (goldcrest lemon cypress)
European Cypress (Goldcrest Lemon Cypress) sits happiest at around 40-60% (moderate) relative humidity. Tolerates average household humidity but dislikes the hot, dry air near radiators, wood stoves and heating vents, which scorches foliage to brown. Keep it cool and away from heat sources, and mist or stand it on a pebble tray during winter when indoor air is driest. 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.
European Cypress (Goldcrest Lemon Cypress) temperature & humidity — frequently asked questions
What temperature is best for european cypress (goldcrest lemon cypress)?
European Cypress (Goldcrest Lemon Cypress) grows best between 13-18°C (55-65°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 european cypress (goldcrest lemon cypress) tolerate?
European Cypress (Goldcrest Lemon Cypress) starts to suffer below roughly 13°C. It tolerates a cold dormant period within USDA USDA 7a-10b (outdoors), but a wet cold root zone is more dangerous than cold air.
What humidity does european cypress (goldcrest lemon cypress) need?
European Cypress (Goldcrest Lemon Cypress) prefers about 40-60% (moderate) relative humidity. Tolerates average household humidity but dislikes the hot, dry air near radiators, wood stoves and heating vents, which scorches foliage to brown. Keep it cool and away from heat sources, and mist or stand it on a pebble tray during winter when indoor air is driest.
How do I raise humidity for european cypress (goldcrest lemon cypress)?
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 european cypress (goldcrest lemon cypress) live outside?
European Cypress (Goldcrest Lemon Cypress) is rated for USDA zone USDA 7a-10b (outdoors) and RHS hardiness RHS H4 (hardy to about -10°C); holds the RHS Award of Garden Merit.
