Permanent, low-maintenance mulch for Indianapolis drainage areas
Compare this material's appearance, uses, and tradeoffs before choosing a finish. This educational guide is not a Mulch Indy product listing; confirm availability and suitability with us for landscape beds, or with independent suppliers for specialist uses.
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.

Depths describe the total mulch layer, including mulch already in place, not the amount to add each year. Adjust planting-bed depth for plant size, material texture, and drainage; keep trunks, stems, and crowns clear. Pathway depths serve a different use, and playground depths must come from product-specific safety documentation.
