Perfectly edged beds and borders

Follow these four steps to keep lawns and beds looking neat


As an interior designer, I’ve always known the importance of well-defined lines. Inside the house or out, a clean, smooth line provides a finished look and a sense of clarity to an area. In my garden, a razor-sharp edge serves as a stage that sets off the careful planning and maintenance I do. Such meticulous attention to detail doesn’t require a lot of work. I use four simple steps to create and freshen up my edges in spring, giving my beds the crisp lines that reflect the effort I put into my garden.

The first step is to cut the edge. If you are creating a new bed, you’ll need to use a garden hose to mark your desired lines. If you are freshening up an existing bed, you can jump right in.

Method 1: The traditional way to do this is to use either a spade or a half-moon edger to move along the line you’ve set out. Neither tool does a great job of cutting curves, and it can be difficult to evaluate the course you’re taking as you move along.

Method 2: Use an Edge Cutter, a tool with a circular blade on wheels. I simply walk behind the tool as it rolls easily along, cutting a continuous line into the soil. The wheels give the tool the mobility to make nice curves, and you can clearly see as you cut, making it easy to evaluate and revise the line of your bed.

Remove the turf

Once you’ve established your edge, refine it with a spade, deepening the cut to 120 to 150mm. If you are cutting a new bed, you also need to cut the turf on the inside of the bed with the spade. The loosened turf can then be removed easily by hand. The goal is to create an edge at a 90-degree angle.

Hone the edge

I like my edges to be razor sharp, so I place hand shears vertically along the trench wall and cut any remaining grass blades from the edge.

Care should be taken not to hold the shears horizontally to avoid destroying the right angle of the edge. I repeat this step two or three times during the growing season to keep my edges looking groomed.

Mulch the bed

The final step is to put down 50mm of mulch on the bed. The mulch not only suppresses weeds but also adds a rich, dark colour to the edge. I mulch right up to the edge of the turf to create a gentle slope from the bottom of the edge to the top of the bed.
