Reitz's sinningia problems — and how to fix them
Reitz's sinningia (Sinningia reitzii) 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.
Spider mites
Hot, dry indoor conditions during summer encourage spider mite infestations on the undersides of leaves. Increase humidity and treat with insecticidal soap or neem oil at the first sign of fine webbing.
Powdery mildew
Poor air circulation combined with high humidity can trigger powdery mildew on leaves. Ensure good ventilation around the plant and avoid wetting foliage.
Leggy growth and poor flowering
Insufficient light is the primary cause. Move to a brighter location or supplement with a full-spectrum grow light placed 20–30 cm above the plant for 12 hours per day.
