INSTALLATION OF LANDSCAPE EDGING Trench preparation requires consistency and can be a laborious task.
Along the entire alignment, excavate a shallow, shaped trench that is approximately 1 inch deeper than the vertical dimension of the edging (Figure 36-3).
For large installations, rental of an edging machine is recommended.
Continue this excavation along the entire length of the edging location.
Begin installation by placing a length of the edging flat against the vertical side of the trench.
Join pieces of edging by cutting 6 inches of the rounded bead off the top of one end of an edging piece.
Steel and Aluminum Edging. Typically reserved for commercial or large installations, a more permanent and higher priced choice for edging is steel or aluminum.
