We have a dogwood and maple planted about 3 yrs ago by same vendor. The dogwood is now half dead with pealing trunk. The nearby maple has rather small leaves but leafed out, but now also pealing trunk bark. The first 2 pics are of the dogwood and the 3rd the maple. Cause? Solution?

Dogwoods as beautiful as they are in Spring are prone to many diseases.
Dogwood anthracnose is a fungal disease what can prove fatal to the tree if left untreated.
The maple could also be infected with the same disease. You might consider contacting the company that planted the trees and discuss with them a plan.
A Certified Arborist in your area might offer a treatment plan that could be worth while.
Below is additional information from the Extension network on IMP regarding Dogwoods.

The vendor wouldn’t take care of the bushes that he planted that died right away so I’m sure won’t come back now 3 years later. The only arborist I have been able to find says they won’t deal with trees this small. Any suggestions if finding a qualified arborist?
