Dogwood tree losing bark

Question

Our flowering dogwood tree bark is cracking and falling of at the tree trunk and has lost most of its bark on the tree trunk. What can we do to safethe tree?.

Answer 1

What you describe is a very dire situation. The tree cannot survive extensive bark loss. The most likely reason for this is that the tree has died from lack of water. But there are other possibilities.
You don't say if the tree still has any green foliage.
Without photos of the tree and the site, and description of the growing conditions and history of soil and water management, we cannot determine the cause and remedy if any.
