Done-for-you mulching · Free · No obligation
Gravel and decorative rock mulch provides a permanent, maintenance-free alternative to organic mulches. Unlike wood-based products, gravel does not decompose, attract insects, or require regular replacement. It's the preferred choice for xeriscape designs, dry creek beds, Mediterranean-style gardens, and areas with drainage challenges.
