Just as edging a flower garden serves multiple purposes, edging may also be done in a number of ways. Edging will help to keep flower gardens neat by creating a barrier between the bed and the yard that surrounds it. Mulch that could slide out of the bed is frequently caught by edging and held in place. Additionally, weeds that try to become established in a bed are repelled by the wall that edging makes. You can edge a garden simply by digging a trench around your bed. Or you can create a physical barrier using metal sheeting, brick, rock or plastic edging strips.
Outline your flower garden with a garden hose to determine where the edging will be placed. Change the shape as often as you need to at this point until you are satisfied with the arrangement of the bed’s edging.
Install a guide by hammering stakes into the ground at points where the bed curves. Tie string between the stakes. You will dig your edging into the soil beneath the strings.
Dig a trench that is 6 inches deep into the soil with a spade and a scoop shovel. Slope the wall of the trench on the flower bed side so that it descends gently into the trench. Make the wall on the lawn side of the trench vertical.
Arrange your metal, plastic, brick or rock edging against the outer wall of the trench. Join all the pieces of interlocking edging together.
Slip stakes through metal or plastic edging. Hammer the stakes into the ground.
Bury the edging on the back side of the trench so that the soil line is level with the front side of the trench.
