If you’re an avid rock collector, you can put your collection to good use as a lawn edging along flower beds. With this type of lawn edging, use any size of stones, arranging them to create a visual tapestry of color and texture. Many gardeners who opt for a mixed stone edging rely on a spritz of grass killer to keep turf from growing around and between rocks. It creates a look like this at first, with the grass being straw colored and dead. After the grass dies, it breaks down, and the rocks take the spotlight.
