Ideal temperature for strawberry ground cherry
Temperature kills fewer strawberry ground cherry 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 18–32°C (65–90°F) is fine; the spot you put the plant in matters more. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Strawberry Ground Cherry is frost-tender (USDA 8–11 (perennial); 3–7 (grown as annual), 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 strawberry ground cherry
Strawberry Ground Cherry sits happiest at around 40–70% relative humidity. Adapts to the typical range of summer humidity in temperate gardens. The fine grey hairs on the plant provide some protection against moisture loss in drier conditions. Adequate plant spacing (45–60 cm) prevents fungal issues in humid climates. 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.
Strawberry Ground Cherry temperature & humidity — frequently asked questions
What temperature is best for strawberry ground cherry?
Strawberry Ground Cherry grows best between 18–32°C (65–90°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 strawberry ground cherry tolerate?
Strawberry Ground Cherry 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 strawberry ground cherry need?
Strawberry Ground Cherry prefers about 40–70% relative humidity. Adapts to the typical range of summer humidity in temperate gardens. The fine grey hairs on the plant provide some protection against moisture loss in drier conditions. Adequate plant spacing (45–60 cm) prevents fungal issues in humid climates.
How do I raise humidity for strawberry ground cherry?
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 strawberry ground cherry live outside?
Strawberry Ground Cherry is rated for USDA zone 8–11 (perennial); 3–7 (grown as annual) 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.
