Ideal temperature for bald cypress bonsai 'cascade'
Bald Cypress Bonsai 'Cascade' is comfortable in any room a person is comfortable in, roughly -15 to 30°C (5-86°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 -15°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Bald Cypress Bonsai 'Cascade' is comparatively hardy (USDA 4-9 (cold-hardy outdoor bonsai), RHS H7). 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 bald cypress bonsai 'cascade'
Bald Cypress Bonsai 'Cascade' sits happiest at around 40-70% relative humidity. Undemanding about air humidity given how wet the roots are kept; natural outdoor humidity is ample. The fine foliage simply needs steady root moisture rather than misting. 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.
