Description

Decomposed granite is like gravel, but finer and generally more stable. It’s formed from the natural weathering and erosion of solid granite, a tough, hard, igneous rock. The DG sold as landscaping material is typically composed of fine three-eighths-inch (or smaller) particles; some may be no bigger than a grain of sand. Colors vary, from buff to brown, and include various shades of gray, black, red, and green.
