If you want a part of your lawn to be maintenance-free, remove the grass and lay down small pebbles. You can create designs with multiple coloured stones and gain a space that doesn't need mowing or watering. This is a simple project, but does require manual labour to make sure the grass won't grow back.
Shovel up as much of the grass as you can. Skim the top 5 cm (2 inches) of the yard to remove as much of the grass and roots as possible.
Till the soil to bring any remaining roots or rhizomes to the surface. Push a tiller back and forth across the lawn area you're renovating. Till to a depth of 10 cm (4 inches).
Spray a non-selective systemic herbicide over the soil. You want to kill all vegetation. Spray evenly over the surface with the aid of a garden sprayer. Apply the herbicide to the grass when there's no chance of rain for two days. You don't want the chemical washed away or diluted before it has a chance to kill the vegetation. The systemic herbicide absorbs through the roots and kills the entire plant.
Wait two weeks and watch for regrowth. Repeat the spraying process if needed.
Rake the soil out smooth.
Spray paint lines to define areas for different coloured pebbles if you aren't going to fill in with one colour. Make the lines straight or form patterns depending on your preferences.
Dig a 10 cm (4 inches) wide trench along the lines for landscape edging. The edging divides the different stones. Make it 5 cm (2 inches) deep so part of the edging is above ground.
Place the edging in the trench. Tap the anchor stakes through the holes at the bottom to hold them in place.
Fill the edges of the trenches in with the soil that you originally removed.
Fill in the area with small pebbles or stones. Use different stones in different sections if you prefer. Create waves, lines, patterns, or pictures depending on where you place the edging.
