Natural, loose decomposed granite
Natural decomposed granite is the plain product, with nothing mixed in. It is weathered granite ground to fines, sold loose by the ton or cubic yard. It is the most common and the most affordable type, and it is where most DG projects start.
You spread it in lifts, wet each lift, and compact it with a plate compactor. Packed and damp, it forms a firm walking surface with a soft, natural feel underfoot. The earth-tone color reads as part of the landscape rather than a hard paved finish.
Natural DG works well for garden paths, informal patios, xeriscape beds, and under-tree areas. It drains well and lets water reach plant roots, which suits it to planted spaces. It also handles curves and irregular shapes easily, since you simply spread it to the edging you set.
The trade-off is upkeep. Loose DG can shed a little material underfoot and can wash or scatter in heavy rain or wind. Foot traffic wears low spots over time, and you top-dress and re-compact those spots as needed. A firm edge restraint around the perimeter keeps the fines from creeping into beds and lawns.
Choose natural DG when you want the softest, most natural look and you accept light seasonal maintenance. It is the right base type for a decorative or low-traffic space. If you need a firmer, lower-maintenance surface, a stabilized or resin-coated product builds on the same material. Whichever type you land on, size the order the same way, by area and depth.
