dogwood trees both white and pink

at the base of my trees which have been in the ground for a couple of years. the bark both below the soil line and above the soil the bark is coming off. it is slowly traveling up the trees.we have had plenty of rain this year.I did put mulch around the base of the trees and it is against the bark. I have been told that is not good. the soil is not the greatest, it has clay in the soil. in Tennessee that is quite common.I’m afraid in time I will loose these trees. I live in east Tennessee. would appreciate your help !!

It sounds like Crown Canker of your Dogwoods and the trunk rot is likely the later stages of this disease.
