The Garden Wizard 4ft Wall is a single 50" wall section. The wall can be used in a variety of ways to create striking borders that are easy to install or to expand the Garden Wizard RBG or Garden Wizard RBGH. Don't struggle with expensive bricks when you can easily buy a few of these landscape borders. The walls can also hold water which can be distributed to a bordering garden via a specially designed soaker hose. The included pin links walls together in a straight line or at 90 degree angles.
