How do I maintain and care for gardening rocks?

Maintaining and caring for gardening rocks is relatively simple compared to other landscaping elements. Since rocks are inorganic and don’t decompose, they require minimal maintenance. However, periodic cleaning can help keep them looking their best. Use a stiff brush or pressure washer to remove dirt, moss, or algae buildup. You may need to occasionally reset or rearrange rocks that have shifted due to weather or foot traffic. For areas with heavy foot traffic, like pathways, consider using a compacted gravel base beneath the rocks for stability. Periodically remove any weeds or unwanted plants that sprout between the rocks. Avoid using herbicides directly on the rocks, as they can discolor or damage the surface.
