More about baby tears plant
Ideal temperature for baby tears plant
Aim for 10-24°C (50-75°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 10°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Baby Tears Plant is comparatively hardy (USDA 9-11 (hardy outdoors in mild climates; frost tender in most UK winters), RHS H3). 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 baby tears plant
Baby Tears Plant sits happiest at around 60-80% relative humidity. Loves high humidity. An ideal candidate for terrariums, bottle gardens, and bathroom windowsills. In dry rooms the foliage browns at the tips and the mat thins out. 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.
Baby Tears Plant temperature & humidity — frequently asked questions
What temperature is best for baby tears plant?
Baby Tears Plant grows best between 10-24°C (50-75°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 baby tears plant tolerate?
Baby Tears Plant starts to suffer below roughly 10°C. It tolerates a cold dormant period within USDA 9-11 (hardy outdoors in mild climates; frost tender in most UK winters), but a wet cold root zone is more dangerous than cold air.
What humidity does baby tears plant need?
Baby Tears Plant prefers about 60-80% relative humidity. Loves high humidity. An ideal candidate for terrariums, bottle gardens, and bathroom windowsills. In dry rooms the foliage browns at the tips and the mat thins out.
How do I raise humidity for baby tears plant?
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 baby tears plant live outside?
Baby Tears Plant is rated for USDA zone 9-11 (hardy outdoors in mild climates; frost tender in most UK winters) and RHS hardiness H3. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
