A new type of landscape edging device, namely RIM EDGING, is invented for mulching around the base of a tree and lawn/mulch edge control. The present invention, RIM EDGING, is a plurality of sections of concrete block that are connected together in a rim-like configuration. Each section comprises a recessed top surface, a wrap-around flange along the inner circumference, and joint connectors for coupling with one another. These design features along with the sturdy construction make the RIM EDGING more effective than the existing edging devices available today for (a) better care of trees, (b) better lawn/mulch edge control, (c) reduced yardwork, (d) reduced cost and maintenance of landscape edging, (e) enhanced appearance of the landscape.
