DIY - Homemade Gabion wall ie rocks encased in wire baskets and used as a retaining wall - creates a dramatic feature in a garden. No directions on link. Nice someone figured out how to landscape with river rock. I swear they grow!
Just 3 simple steps: Pour quick-set concrete into the mold on any flat surface. Smooth with a trowel. Wait one minute, lift mold and move on. This mold measures 20 inches x 24 inches x 2 inches, and holds one 60 pound bag of premix concrete.
