A method of installing an edging system for a unit pavement system includes positioning a paver-contacting surface of an edge restraint against an edge of a unit pavement system including a plurality of paver units, and driving a horizontal stake in a generally horizontal direction underneath at least one paver unit of the plurality of paver units and into a granular material layer upon which the unit pavement system is supported such that the horizontal stake is operatively connected with the edge restraint. The edge restraint includes a horizontal section and a vertical section joined at a corner. The vertical section extends upwardly from and generally perpendicular to the horizontal section. An edging system for a unit pavement system is also disclosed.
