Ideal temperature for coffee-leaf anubias
Aim for 22-28°C (72-82°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 22°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Coffee-leaf Anubias is comparatively hardy (USDA N/A (aquatic, tropical), RHS N/A). 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 coffee-leaf anubias
Coffee-leaf Anubias sits happiest at around N/A (submerged aquatic) relative humidity. Fully submerged in freshwater. Also kept emersed in very humid vivariums or paludariums where the leaves grow above water. 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.
Coffee-leaf Anubias temperature & humidity — frequently asked questions
What temperature is best for coffee-leaf anubias?
Coffee-leaf Anubias grows best between 22-28°C (72-82°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 coffee-leaf anubias tolerate?
Coffee-leaf Anubias starts to suffer below roughly 22°C. It tolerates a cold dormant period within USDA N/A (aquatic, tropical), but a wet cold root zone is more dangerous than cold air.
What humidity does coffee-leaf anubias need?
Coffee-leaf Anubias prefers about N/A (submerged aquatic) relative humidity. Fully submerged in freshwater. Also kept emersed in very humid vivariums or paludariums where the leaves grow above water.
How do I raise humidity for coffee-leaf anubias?
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 coffee-leaf anubias live outside?
Coffee-leaf Anubias is rated for USDA zone N/A (aquatic, tropical) and RHS hardiness N/A. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
