# Understanding Decomposed Granite: A Versatile Landscaping Solution Decomposed granite (DG) is a popular and aesthetically pleasing material widely used in residential and commercial landscaping. Despite its name, decomposed granite is not truly granite at all—it’s a naturally weathered rock consisting primarily of fine granular particles formed from the breakdown of weathered granite. This unique composition makes DG a durable, porous, and attractive option for driveways, walkways, patios, and decorative garden features. ## What Is Decomposed Granite? Decomposed granite is created when large granite rocks break down over time due to natural weathering processes like freeze-thaw cycles and erosion. The result is a soft, granular material composed mostly of quartz and feldspar minerals mixed with sand, silt, and clay. Unlike solid granite, decomposed granite is loose and granular, which allows for excellent drainage while maintaining a stable and rugged appearance.
