Edging is commonly used in landscaping to separate a flower bed from the lawn area, to contain mulch and prevent it from spreading outside its confines, and to give the overall landscape a well-groomed look. Edging a flower bed also protects delicate flowers from the sharp blades of a lawn mower. There are many types of edging options available at nurseries, home improvement stores and garden centers. Depending on the surrounding landscape and the exterior of your home, you can install wood, decorative concrete blocks, metal and plastic edging.
How to Edge Your Flower Bed
Demarcate the area around the flower bed that you want to edge to get an idea of how much to purchase. Simply spray around the flower bed with a can of spray paint as straight as you can or use powdered chalk. Measure the outline with a measuring tape and purchase edging of your choice.
For a curved flower bed, line the area with your garden hose and measure with measuring tape.
Purchase edging depending on the type you want to install around your flower bed, ensuring it complements the landscape. Also decide whether you want the edging above the ground to form a physical barrier that is visible from afar, or one that is flush with the surface, so that it sinks into the ground with the lip above the surface.
Dig a trench over the marked line with a square-edged spade or edger. The trench should be at least 2 inches wide and about 6 inches deep or more, depending on the height of the edging you have purchased.
Collect the shoveled soil in a wheelbarrow because you will be using it to backfill the trench.
Add an inch of sand into the trench to form a secure base for the edging.
Set one block of edging into the trench to determine its height. Step back to see how it looks, and add or remove sand to raise or lower the edging in the ground appropriately.
Lay all the pieces or blocks of the edging vertically into the trench, pushing each with force to set it in place. You can also hammer or tamp it down to set it firmly in the trench.
Fill the gaps around the edging in the trench with collected soil from the wheelbarrow so it stays secure and does not wobble.
Walk the entire length of the flower bed to ensure the edging is secure.
Water the newly installed edging around the flower bed so the soil around it sets in place and grips it firmly.
