If a container grown tree planted about 6 years ago (Maybe about 8 feet tall now) and growing nicely had soil added around the trunk this spring because of construction in the area at a level perhaps 4-6 inches higher than the previous ground level. Is that a good thing or bad thing and why or why not.

Placing 4 to 6 inches of soil around an established tree is not a good thing. Tree roots are quite shallow. Most tree roots are located in the upper 12 inches of soil. Placing 4 to 6 inches of soil around a tree may bury some of the tree's roots so deeply that they suffocate and die.
