Likely causes
Leaf Spot Disease
Most likelyHow to tell: You will see small brown or black spots, often with a yellow halo around them. These spots may grow and merge as the infection spreads.
What to do: Remove and dispose of all affected leaves immediately to stop the spread. Water only at the base of the plant to keep the foliage dry. Apply a copper based fungicide if the infection persists.
Powdery Mildew
PossibleHow to tell: This looks like a dusting of white flour on the surface of the leaves. It often happens when air circulation is poor.
What to do: Thin out nearby plants to improve airflow around your Coral Bells. Avoid overhead watering during humid weather. Use a neem oil spray if the white coating covers more than a quarter of the leaves.

When to worry
Worry if the spots are spreading rapidly to new growth or if the plant begins to lose its vigor. A few old leaves with spots are normal and can simply be trimmed away.
Stopping it coming back
Water at the soil level early in the morning and maintain proper spacing between plants to keep leaves dry.

Questions people ask
- Should I cut off all the spotted leaves?
- Yes, removing infected foliage helps stop the spread of spores. Just make sure to sanitize your shears with alcohol between cuts.
- Will my plant die from leaf spot?
- Usually no, provided you catch it early. It mostly affects the appearance of the plant rather than killing it outright.
