Use the edger to cut straight down into the grass and mark out a 1-foot-wide strip in the turf, and make it a few feet long.
Insert the tip of the spade into the line from the edger, then tilt it back at a sharp angle, close to parallel to the ground. Push the spade toward the center of the 1-foot-wide strip, and work your way around the entire strip until the turf is loose from the ground.
Roll the strip up tightly with your hands, rolling it like a piece of pastry or a newspaper. Repeat steps 1 through 3 for any remaining areas of turf that need removal.
