Camellias are very susceptible to honey fungus. You may see the telltale mushrooms forming in autumn.
Sooty mound
This black fungus grows on the sugary honeydew secreted by sap-sucking insects like aphids.
Buds dropping
There are a number of reasons for this; earlyflowering varieties can be sensitive to frost.
