Decorative rock is a permanent, low-maintenance alternative to mulch for landscape beds, pathways, and drainage features. Unlike mulch, rock does not decompose, fade, or need annual replacement. A one-time investment that lasts decades.
Pea gravel works well for pathways and between stepping stones. River rock is ideal for dry creek beds, garden borders, and decorative accents. Lava rock is lightweight and works well in beds around heat-loving plants. Mexican beach pebble creates a polished, upscale look.
Before ordering, always install landscape fabric and measure your exact area. Use LotSite to paint your landscaping beds on a satellite map and get the square footage, no tape measure required.
Enter your address and paint the area to cover. The square footage adds up as you paint.
