Ideal temperature for divine orange new guinea impatiens
Temperature kills fewer divine orange new guinea impatiens 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 10 to 32°C (50 to 90°F) is fine; the spot you put the plant in matters more. Below roughly 10°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Divine Orange New Guinea Impatiens is frost-tender (USDA 10-12 (grown as a half-hardy annual in zones 2-9), 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 divine orange new guinea impatiens
Divine Orange New Guinea Impatiens sits happiest at around 50-70% relative humidity. Prefers moderate to high humidity. Handles outdoor humidity levels well. In very arid conditions, water more frequently and mulch to reduce moisture loss. 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.
