Troubleshooting
African Violet 'Optimara' problems — and how to fix them
African Violet 'Optimara' (Streptocarpus sect. Saintpaulia 'Optimara') 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.
Failure to bloom
Almost always too little light or too much nitrogen. Move to bright indirect light and switch to a high-phosphorus violet feed.
Leaf ring spot
Pale rings appear where cold water touched the leaves. Always use tepid water and water from below.
Crown and root rot
Overwatering or a waterlogged crown causes a mushy, collapsing centre. Let the surface dry slightly and never leave the pot standing in water.
Powdery mildew
A white dusty film in cool, damp, stagnant air. Improve airflow, reduce humidity around the leaves and remove affected foliage.
