Water the entire lawn with a garden hose or sprinkler two to three days before you plan to remove the sod. Make sure the soil is wet to a 3- or 4-inch depth by digging down into it with screwdriver to test it. The water loosens the soil and makes digging much easier.
Walk to the edge of your installation area and measure over 12 inches. Insert an edger tool into the ground parallel to the longest side of the installation area. Step on the top of the metal base with your foot to cut down into the sod.
Remove the edger, place it directly beside the first location and repeat the process. Continue this technique all the way to the end of the installation area to cut the sod into 12-inch-wide strips.
Walk back to within 1 to 2 feet of the starting location, and cut the long sod strip widthwise with the edger, which creates short strips that are easier to remove than long ones.
Place the blade of the spade at the location of one of the cut lines and push it under the sod. Lean back gently on the spade handle to pry the sod's roots up from the ground.
Grasp the sod with your hands and pick it up. Place the sod in a new location or set it off to the side out of the way.
Continue cutting and removing sod until all of it is removed.
