发明名称 Tree ring for prevention of vegetation growth at trunks
摘要 A tree ring that inhibits and/or prevents vegetation growth around the trunks of trees. The tree ring comprises an elastic outer peripheral edge and an elastic inner peripheral edge. In between elastic outer peripheral edge and the elastic inner peripheral edge is a flexible sheet. The flexible sheet has a plurality of holes. The tree ring is removably secured onto a tree pot of any dimension, size, or shape. The elastic outer peripheral edge stretches around the rim of the tree pot, and the elastic inner peripheral edge snugly fits around a tree trunk. It is noted that the distance between the elastic outer peripheral edge and the elastic inner peripheral edge that makes up flexible sheet may vary.
