Pour pebblestone in landscaping as a mulch cover for plants. It creates a different look for the landscaping from the more traditional bark mulch or pine needles.
Spread pebblestones around stepping stones on a path to help define the walkway. This also helps block the light from the soil and helps keep weeds from growing.
Dig a curving and winding space through the landscape and line it with pebblestones. Place a few medium-sized river rocks in the space to create the illusion of a dried-up creek bed. You can plant vegetation along the edges to enhance the illusion.
Form a design with different shades of pebblestone. Install landscape edging to form the various shapes, and then fill in with the shades of pebbles. Dig 4-inch-wide trenches 2 inches deep for the edging material. Place the edging in the trenches and tap anchor stakes through the holes to secure it at the base. Fill the trenches in, and then add the pebbles.
