Camelia needs help!
I have four Camelia bushes in my yard and they all look very sickly. They all did bloom this year, but the leaves are yellowish and moldly on the surface and on the underside, there are some rusty looking scales. What are these? I tried spraying them with a fungicide, but it didn't do much to it. What should I do to get rid of this disease? Here's a picture of some of the leaves.
