Abstract: A landscaping device comprises a plurality of segments which may be interconnected to surround a plant or other vertical object. Each segment is made of a plurality of radially extending walls which are spaced to provide a plurality of reservoirs. The reservoirs are triangular-shaped to direct water toward the root system of the plant. The bottom surfaces of the reservoirs are permeable so that water which fills the reservoir through rain or run-off will seep slowly into the ground surrounding the plant. The apparatus has a substantially flat top so that a lawn mower or other implement may easily drive over it to facilitate trimming the vegetation surrounding the element.
