Water-washed stone garden design refers to the artistic arrangement of stones in a garden, where the stones are meticulously cleaned and polished. This design technique is often used to create visually appealing and natural-looking garden landscapes. It involves selecting stones of varying sizes, shapes, and textures, and arranging them in a way that complements the overall garden aesthetic. The process may also include the use of other elements like plants, water features, and pathways to enhance the overall design.
