Quotation: I have seen some landscapers use very deep layers of mulch—a foot or more in tight rings around trees and shrubs. Is this a healthy practice?…This is sometimes called volcano mulching because of the steep sides and hollow center around the base of the tree. It may be better than no mulch at all, but it can cause problems, especially with newly planted trees.

This catchword has yet to be researched.
Comments:
I was once told, by a Minneapolis park employee, that the extra mulch discourages lawnmowers (from injuring the tree’s bark). Evidence of a covert power struggle between arborists and landscapers?
