How to Control Edges Without Chemicals

Force an edger, sharp spade or shovel into the ground to make a V-shaped ditch or trench 4 to 6 inches deep and wide between sections of the landscape you wish to separate. Although it's a relatively simple and cost-effective way to control edges, it's far from permanent, allowing a great deal of flexibility if you want to change the border later.

Re-cut the trench or small ditch once or twice during each growing season, or as needed, to sever any roots and stems growing into the gap.

Choose a physical barrier or edging that fits in with your vision for the landscaping, whether it's plastic or poly edging, metal, untreated or treated wood, bricks, stones or poured concrete.

Install the physical barrier or edging material between sections of the landscape. Extend any edging or base material at least 6 inches below ground to contain or exclude vigorous, creeping grasses.

If you do not want to install edging or create a small trench, maintain a neat border by simply trimming edges with a power edger or weed eater or pulling stray plants along lawn edges every time you mow the grass during the growing season. Regular raking can pull wood chips and gravel back in position.
