Garden edging helps to define the border between the flower bed and the lawn, and prevents soil erosion in a sloped garden bed. There are many edging materials to try, including concrete, wire, bricks, or stones, and all can be installed in an afternoon. For an eco-friendly take on edging, try this whimsical wine bottle project from Charlotte Hupfield Ceramics. The colorful glass reflects the sunshine while creating a unique look for a stand-out garden.
