When to worry
If the spots are spreading rapidly across the whole plant, it is a serious concern. A few isolated spots are usually just a minor cosmetic issue.
Stopping it coming back
Water at the base of the plant rather than over the leaves, and ensure the plant has enough space for air to move.

Questions people ask
- Are these spots a sign of a pest?

- Should I use a fungicide?
- Only if the spots are spreading quickly after you have improved air circulation. Good cultural care is usually enough.
