Ideal temperature for lemon tree 'meyer'
Temperature kills fewer lemon tree 'meyer' 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 13-29°C (55-85°F) is fine; the spot you put the plant in matters more. Below roughly 13°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Lemon Tree 'Meyer' is frost-tender (USDA 8b-11 outdoors (hardier than true lemons); container-grown and overwintered indoors elsewhere, RHS H2). It cannot survive a frost, so in most of the US and UK it lives indoors year-round or summers outside and comes back in well before the first autumn frost — once nights drop toward 10-12°C is the cue, not the first frost warning. Acclimate it over a week when moving between indoors and out so the leaves do not shock.
Humidity for lemon tree 'meyer'
Lemon Tree 'Meyer' sits happiest at around 40-60% relative humidity. Handles normal indoor humidity but benefits from a boost in dry, heated winter rooms to deter spider mites and reduce bud drop. Keep away from radiators and cold drafts. 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.
Lemon Tree 'Meyer' temperature & humidity — frequently asked questions
What temperature is best for lemon tree 'meyer'?
Lemon Tree 'Meyer' grows best between 13-29°C (55-85°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 lemon tree 'meyer' tolerate?
Lemon Tree 'Meyer' starts to suffer below roughly 13°C. It is frost-tender and will be damaged or killed by a frost, so bring it indoors once nights fall toward 10-12°C.
What humidity does lemon tree 'meyer' need?
Lemon Tree 'Meyer' prefers about 40-60% relative humidity. Handles normal indoor humidity but benefits from a boost in dry, heated winter rooms to deter spider mites and reduce bud drop. Keep away from radiators and cold drafts.
How do I raise humidity for lemon tree 'meyer'?
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 lemon tree 'meyer' live outside?
Lemon Tree 'Meyer' is rated for USDA zone 8b-11 outdoors (hardier than true lemons); container-grown and overwintered indoors elsewhere and RHS hardiness H2. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
