Dogwood bushes

I have three dogwood bushes. They have red branches in the winter and grow white leaves in the spring and summer. They start off well, but by summer have dark spots in the leaves. They were delivered and planted this way 2 years ago. Last summer, the same thing happened. Are they just damaged plants or is there something that I can do for them?

There are many copper fungicides that can be applied, but I recommend using wettable sulfur and dolomitic lime to correct fungal issues such as this. It will also recondition the soil to a more nourishing condition for the tree. You may not notice improvement until the next year, but it will kill off most pathogens in the soil.
