Hoop edging is perhaps the simplest edging material to install because no digging is required. Hoops come in rustic willow for a cottage look or sturdy iron for traditional gardens. Plastic-coated aluminium hoops are an economical choice. When choosing hoop edging, consider the style of your home, as well as your climate. Willow hoop edging probably won't last long in climates with heavy snows and rains, while iron edging is more durable.
Lay down a garden hose to delineate the boundaries of the flower bed.
Sprinkle powdered chalk along the garden hose to create an outline of the boundaries. Remove the garden hose.
Remove grass along the chalk line and in the intended flower bed area with your shovel to prepare the flower bed. Dig the flower bed to a depth of 6 to 8 inches before planting to loosen soil.
Set a piece of edging on the grass adjacent to the flower bed.
Push the spikes at the bottom of the edging securely into the soil so the hoop is parallel with the edge of the flower bed.
Tap the hoops of the edging in several places with a rubber mallet to securely push it into the ground.
Install the rest of the edging, butting each piece up to the next one.
Hoop edging won't keep grass out of flower beds as well as pavers or metal edging. Grass grows underneath edging, requiring frequent trimming. String trimmers and lawnmowers easily damage willow edging so use care when operating equipment around this material.
