Tree trunk problem
We have a tree trunk that appears to be scaling off bark. Not sure the problem or the solution. We believe it to be a Korean Dogwood, but not sure. The tree is in full sun. We've attached 2 photos for your consideration. Property is located in Sykesville, MD. Thanks for your comments.
Based on your description and photos the tree looks like a Kousa dogwood. It is normal for the bark to exfoliate.
We notice that the tree is planted too deeply and has excessive mulch around the trunk. You should be able to see the flare at the base of the trunk where it joins the root system. Remove the mulch from the base of the trunk. Make sure it is no thicker than several inches and keep away from the base of the trunk. If you see no flare, you can carefully remove the soil from the circumference of the trunk to the point where the trunk flares out into root growth.
