Need to end your Garden Wizard rock wall section against a flat surface such as house cinder blocks or a deck? Just use the Garden Wizard Border Finish Kit to close the connector gaps on your terminating rock wall. Each kit comes with a single peg stake to hold the blocks in place (stakes can work on flat surfaces or be driven into the ground by sliding a piece of metal or rebar into the sleeve). Kits are available in all Garden Wizard rock wall colors.
