When your garden calls for something dramatic, place a boulder amid your plants. To ensure that the boulder looks natural in the landscape, the area must be properly prepared. You can place a boulder with a little effort and a few basic garden supplies.
Walk around your garden to determine the precise placement for the boulder, then place a large box or container there to simulate the boulder in the landscape. Step back and determine if you like the effect.
Draw a line on the landscape with chalk to mark where you will place the boulder.
Dig into the marked area with a shovel and remove enough soil so that approximately 1/3 of the boulder will be under the soil. Put the removed soil aside.
Cut a piece of landscape fabric that is large enough so it will extend approximately 2 feet out from the edges of the boulder. Spread the landscape fabric in the excavated area and press it into place.
Lift the boulder onto a tree dolly with the help of an assistant, then move the boulder into position.
Shovel the excavated soil onto the landscape fabric that extends from under the boulder. Apply 2 inches of mulch over the soil to finish covering the landscape fabric.
