Abstract
Abstract Two or more fiberglass preformed sections interfit to form a cover about the base of a tree. The sections are provided with a series of underlying rings spaced apart concentrically radially outward from a central opening through which the tree extends. The rings provide reinforcement to each section and function as guides for subsequent cutting of larger holes as the tree grows. When concrete or the like is to be poured about the tree, a framework is used as a concrete form to insure the cover sections fit together properly.
