Answer: It is difficult to diagnose leaf spots long distance. I would suggest you contact your county extension to obtain a specific diagnosis of the leaf spots on your camellia. They may appreciate photos of the overall plant and closeups of the affected leaves, as well as possibly a freshly cut sample enclosed in a clear plastic bag and kept cool so it stays fresh. If it is something that requires a chemical control, they will be able to give you the most up to date recommendations on what to use and how/when to use it for best results. I hope it's nothing too serious.
