Hamilton's Strobilanthes problems — and how to fix them
Hamilton's Strobilanthes (Strobilanthes hamiltonianus) 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.
Bud drop and failure to flower
Caused by low humidity, sudden temperature drops, or erratic watering. Maintain consistent moisture and humidity during the bud formation stage. Avoid moving the plant while buds are forming.
Aphids on new growth
Soft shoot tips attract aphid colonies, causing distorted new leaves. Knock off with a strong water jet or treat with insecticidal soap. Regular inspection of growing tips prevents build-up.
Powdery mildew in poor air circulation
A white powdery coating on leaves can develop in warm, humid, still air. Improve ventilation around the plant, avoid wetting foliage, and treat with a dilute potassium bicarbonate or neem solution.
