Troubleshooting
Streptocarpus 'Black Panther' problems — and how to fix them
Streptocarpus 'Black Panther' (Streptocarpus 'Black Panther') 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.
Overwatering and root rot
Constantly wet soil rots the fleshy roots and collapses the plant. Let the surface dry between waterings and reduce water sharply in winter.
Sparse flowering
Low light or under-feeding. Increase indirect light and feed regularly with a high-potash feed through spring and summer.
Faded or scorched blooms and leaves
Direct sun bleaches the dark flowers and burns foliage. Shift to bright but indirect light.
Brown leaf tips
Dry air or fertiliser salt build-up. Flush the soil periodically and raise humidity slightly if room air is very dry.
