Sizes & Colors
Black Shredded Mulch
Shredded strips of bark and wood, typically 1-4 inches long, dyed with carbon-based black colorant. The dye is non-toxic and safe for plants and pets. Double-shredded black mulch mats together better and resists displacement.
Decomposed Granite
Decomposed granite is a mix of fine particles and small chunks, typically 1/4" and smaller. Colors include gold, tan, brown, gray, and reddish-brown depending on the granite source. Stabilized DG (with resin binder) creates an even firmer surface.
