Stone pavers have a wide variety of uses in the home landscape, including patios, walkways, retaining walls and flower bed edging. Another use for pavers is creating a circle around the base of trees to improve the appearance of the landscape. It's best to only install pavers around mature trees so that you do not have to widen the ring once the trunk expands with age. If desired, you can even place plants within the paver ring for an improved appearance.
Place the end of a tape measure at the base of the tree trunk, and measure outward 3 to 6 feet.
Lay a piece of string at this location so that it is perpendicular to the tree trunk. Work your way around the tree measuring outward to the desired distance, and then wrap the string around the trunk in a circle.
Use spray chalk to spray all the way around the outer edge of the string to mark the edge of the tree ring in the soil. Set the string aside.
Dig down along the chalk outline using a spade, and create a trench all the way around the trunk. Make the trench at least 3 to 4 inches deep and the same width as the pavers, which is typically at least 5 to 6 inches.
Hit the ground inside the trench repeatedly with a plate compactor to pack the soil down firmly.
Spread a 2-inch layer of sand inside the trench, and use the plate compactor to pack it down.
Lay one of the pavers into the trench with the widest side facing away from the tree. Place additional pavers directly bedside it until you have a single layer of pavers all the way around the tree. Place a level across the pavers as you insert them to ensure they are all the same depth.
Start a second row by placing another paver on top of two underlying pavers, straddling the joint between the two. Place additional pavers directly next to the first until you have a second circle all the way around the tree to complete the ring.
