Troubleshooting
Primrose-leaf Streptocarpus problems — and how to fix them
Primrose-leaf Streptocarpus (Streptocarpus primulifolius) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf scorch and bleaching
This species is adapted to deep shade; even moderate direct light causes pale, bleached patches and dry leaf margins. Always position on a north-facing or heavily shaded windowsill, well away from unfiltered glass.
Powdery mildew
Poor air circulation combined with consistently high humidity can encourage powdery mildew on the leaf surface. Improve ventilation around the plant while maintaining humidity at the root level with a pebble tray rather than enclosed in glass.
