New Guinea Impatiens problems — and how to fix them
New Guinea Impatiens (Impatiens hawkeri) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Wilting in heat
Sun and warmth dry pots fast; plants droop but recover when watered. Mulch beds and water containers more frequently in hot spells.
Leggy, sparse growth
Too little light or over-feeding with nitrogen. Move to brighter conditions and pinch tips to encourage bushiness.
Cold damage
Frost-tender; even a light chill blackens foliage. Do not plant out until nights are reliably above 10°C / 50°F.
Spider mites / aphids
Stippled or sticky leaves in dry conditions. Rinse foliage and treat with insecticidal soap; keep plants well-watered.
