Some of My Camellia Plant Leaves Are Turning Yellow
On the yellowing leaves of my camellia plant, I notice a slight profusion of tiny, immobile raised brownish bumps on the undersides of the yellowing leaves. I can't find a corresponding description in the research I've done, and wonder if you can help.

The bumps are most likely scale insects, which are causing stress to the plant, thus reaulting in the yellowing of leaves. You may also notice a sticky substance, called honeydew, on the camellia as well. You can try treating your camellia with neem oil and this should help take care of the pest issue.
