Ideal temperature for 'cherokee purple' tomato
Temperature kills fewer 'cherokee purple' tomato 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 18-29°C (65-85°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
'Cherokee Purple' Tomato is frost-tender (USDA Grown as a warm-season annual in zones 3-11; needs frost-free conditions, 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 'cherokee purple' tomato
'Cherokee Purple' Tomato sits happiest at around 50-70% relative humidity. Tolerates a wide range outdoors; very high humidity with poor airflow encourages fungal blights, so space and prune for ventilation. No misting. 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.
'Cherokee Purple' Tomato temperature & humidity — frequently asked questions
What temperature is best for 'cherokee purple' tomato?
'Cherokee Purple' Tomato grows best between 18-29°C (65-85°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 'cherokee purple' tomato tolerate?
'Cherokee Purple' Tomato 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 'cherokee purple' tomato need?
'Cherokee Purple' Tomato prefers about 50-70% relative humidity. Tolerates a wide range outdoors; very high humidity with poor airflow encourages fungal blights, so space and prune for ventilation. No misting.
How do I raise humidity for 'cherokee purple' tomato?
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 'cherokee purple' tomato live outside?
'Cherokee Purple' Tomato is rated for USDA zone Grown as a warm-season annual in zones 3-11; needs frost-free conditions 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.
