Not every flower bed needs to follow the traditional norms of hugging the exterior of the house. Round flower beds allow gardeners to landscape in the middle of the yard. By creating round, centrally located flower beds, you draw emphasis to the middle of the yard. It is important to be careful when mowing to keep the grass clippings from away from the gardening beds. Design round flower beds to incorporate striking elements to your landscape.
Draw a diagram of the yard and include the driveway, home, pathways, flower beds and immovable objects, such as sheds. Measure the square footage of the yard by multiplying the length by the width. Indicate on the diagram where you would like to place your round flower beds. You can use the square footage to create a uniform look of perfectly centred flower beds or draw on an eclectic look of multiple beds placed in various locations in the yard.
Place a stake where the centre of the flower bed will be located. Measure from this centre where you want the outside or perimeter of the flower bed and place a stake into the soil. Move around the centre and place stakes in a circular fashion around the proposed bed.
Tie one continuous string to each stake. Step back and check out the flower bed. Repeat the process if creating multiple beds in the yard.
Drive a shovel into the grass and lift up to remove the grass roots from underneath. Throw the grass into compost or burn.
Spray the inside of the flower bed with pre-emergent herbicide to kill the grass seeds in the soil. Give the herbicide several weeks to prevent seeds from germinating before planting flowers.
Create a border around the round flower bed by using bricks, wood or mulch to prevent grass from impeding on the bed.
Avoid using a broad spectrum herbicide to remove the grass from the beds, because it will kill off the surrounding grass.
