Cobblestone

Functional benefits

​​

• Keeps mulch in place. A raised stone lip (typically 3"–6" above grade) creates a physical barrier that prevents bark, chips, and shredded mulch from washing into the lawn during storms or being blown out by leaf‑blowers.

• Clean mowing edge. A 4"‑wide stone strip provides a stable track for a mower wheel, letting you cut right up to the bed line and greatly reducing the need for string‑trimming.

• Durable. Natural cobblestone won’t rot, warp, or fade like plastic or wood. It’s UV‑stable, shrugs off line‑trimmer scuffs and pet traffic, and—when set on a compacted base—handles freeze–thaw without deforming.

• Permeable joints. Sand or stone‑dust joints allow rainfall to infiltrate instead of sheeting off like a poured curb, which helps reduce runoff and minor erosion. 

• Pest‑resistant. Stone is inert and offers no food or nesting material, unlike landscape timbers that can attract termites or carpenter ants.

• Handles slopes. A single raised course holds mulch on gentle grades; on steeper sections you can step the edge or add a second course. Setting stones with a slight inward lean helps resist outward pressure from mulch.

• Aesthetics. Cobblestones give a crisp, finished line between lawn and beds. Their natural texture and color suit both cottage and formal styles and frame plantings so foliage and flowers stand out.
