1.3 Erosion Control
Rocks help stabilize the soil and prevent erosion, especially in sloped areas or regions with heavy rainfall. By creating a protective layer on the soil surface, rocks minimize soil displacement and runoff, preserving the integrity of your flower beds and preventing damage to surrounding areas. Studies from Arizona State University’s School of Earth and Space Exploration show that rock mulches significantly reduce soil erosion compared to bare soil or organic mulches.
1.4 Weed Suppression
Rocks can act as a natural barrier to weed growth by blocking sunlight and preventing weed seeds from germinating. While they may not eliminate weeds entirely, they significantly reduce their presence, minimizing the need for herbicides and manual weeding. Regular maintenance, such as removing any weeds that do emerge and replenishing the rock layer as needed, will further enhance weed control.
