Brick landscaping around a tree can act as a solid retaining lip for mulch that you plan to place around the tree. Brick pavers can replace ugly plastic edging to add a colorful touch to your landscaping. Installing brick landscaping requires more work than installing plastic edging but the result is a cleaner and more attractive appearance.
Place a circle around the tree with marking paint to set the inner boundary of the brick edging. Place a second circle around the first circle to mark the outer limit of the edging. The distance between the two circles must equal the thickness of the bricks.
Place several stakes into the hole and place a string onto the posts. Use a line level to ensure the string remains level. This will serve as the top of your edging.
Excavate the space between the circles with a shovel approximately half as deep as the bricks are long.
Fill the trench approximately half way full with cement and level it out with a trowel.
Place the first brick into the trench long way and position it at a 45-degree angle to the ground. Set it deep enough that the tip of the brick's corner touches the string, Pack cement on the side the brick leans to prevent the brick from falling.
Position the second brick next to the first brick and then install each additional brick until you complete the circle around the tree. Once completed, remove the stakes and string. Allow 24 hours for the cement to dry.
Backfill the trench with as much dirt as possible. Tamp the dirt with a tamper to compact it in the ground.
