Why do my dogwoods (Cornus florida) keep dying?

For years now I have been planting various color dogwoods, but after a year or two they all seem to die. They usually don't make it through the winter. Some of these dogwoods tend to get a whitish powdery residue on the leaves in late summer. Do you know why they are dying and is there anything I can do to prevent it from reoccurring?
