More about wild garlic vine
Ideal temperature for wild garlic vine
Wild Garlic Vine is comfortable in any room a person is comfortable in, roughly 18–35°C; minimum 1–2°C briefly for established plants (64–95°F; minimum 34–36°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 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Wild Garlic Vine is frost-tender (USDA 9-11, RHS H1c). 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 wild garlic vine
Wild Garlic Vine sits happiest at around Moderate to high (50–80%) relative humidity. Native to humid Amazon lowlands, so benefits from moderate to high humidity. In dry environments, occasional misting helps. In subtropical and tropical outdoor gardens, ambient humidity is generally adequate. Good air circulation prevents fungal issues even in humid conditions. 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.
Wild Garlic Vine temperature & humidity — frequently asked questions
What temperature is best for wild garlic vine?
Wild Garlic Vine grows best between 18–35°C; minimum 1–2°C briefly for established plants (64–95°F; minimum 34–36°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 wild garlic vine tolerate?
Wild Garlic Vine starts to suffer below roughly 18°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 wild garlic vine need?
Wild Garlic Vine prefers about Moderate to high (50–80%) relative humidity. Native to humid Amazon lowlands, so benefits from moderate to high humidity. In dry environments, occasional misting helps. In subtropical and tropical outdoor gardens, ambient humidity is generally adequate. Good air circulation prevents fungal issues even in humid conditions.
How do I raise humidity for wild garlic vine?
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 wild garlic vine live outside?
Wild Garlic Vine is rated for USDA zone 9-11 and RHS hardiness H1c. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
