Growing Guide & Production Protocols
Cultivation & Growing Guidelines
New Guinea Impatiens are prized for their oversized, iridescent blooms and glossy foliage that stays vibrant even in summer heat. Best results come from bright shade or filtered sun, consistently moist and well‑drained soil. With strong branching, high humidity tolerance, and nonstop flowering, they excel in patio containers, hanging baskets, and shaded landscape beds – delivering season‑long color where other annuals fade.
Stick promptly, avoid over‑misting, maintain 72°F (22°C). pH 5.8–6.2, EC 0.8–1.0. Feed 50 ppm N early, then 100 ppm N. Fungicide at sticking and week 2; no pinch recommended.
