Garden beds are used as decorative accents to lawns. People grow various plants in garden beds, including trees, bushes, small shrubs and flowers. Garden beds typically use mulch or landscape rock spread in a thin layer around the plants. The mulch or rock keeps weeds from sprouting up, which helps limit the maintenance required.
Pick a location for your garden bed. Mark the outline of the bed on the lawn with marking paint.
Set up a lawn sprinkler and water the soil thoroughly where you want to create your garden bed. Water until you can push a screwdriver into the ground easily.
Take a flat spade and push it into the ground 3 inches around the entire perimeter of your marked out garden bed. Step into your bed. Take your spade and push it into the ground at an angle toward your vertical cut. The cut should begin about 6 inches in from the vertical cut. Repeat this process around the entire perimeter of your bed.
Lift out the sod strip you created from making the two cuts and dispose. You should now have a small trench around the entire perimeter of the bed. This prevents the grass from spreading into the bed and keeps the mulch contained in the bed.
Mix the appropriate amount of non-selective herbicide concentrate and water together in your pump-up sprayer. Read the instructions on the herbicide for the indicated rate. Spray all the grass inside the bed until wet.
Wait the length of time indicated on the herbicide bottle before replanting. Plant the desired plants in your bed.
Spread a 2 to 3 inch layer of mulch or decorative stone around the plants in your bed.
