Question
Eastern NC, Dogwood 10 inches at base and about 25 ft tall.  Good foliage.  Bark is separating from the tree and there is a patch about a foot sqaure missing completely. Bare wood is dark and has a white fungus growing on it.  The rest ot the bark of the main trunk is falling off if mildly touched.  This is occuring from the base to about a foot after the specimen y's into branches (3 to 5 ft).  Is it to late?  What can be done to help this tree to be healthy again? No bugs noted other than a few small ants crawling up and down.

Answer
If the tree's foliage is good it should be ok--not sure why it is loosing the bark. I would call the local office of the N.C. Division of Forestry (state agency) and ask one of their Foresters to come out and take a look. This is a free service and an on the ground inspection should be able to ID any problems. Here is their web page link to the County offices information.
