Substitution of moss with karesansui

Quick answer：

Karesansui, or 'dried landscape,' is a Japanese Zen garden style that uses gravel, rocks, and occasionally moss to represent a natural landscape in miniature. The term 'substitution of moss with karesansui' refers to replacing the traditional living moss in a karesansui garden with a non-living, gravel-based design. This change is often made for practical reasons, such as moss maintenance or to achieve a specific aesthetic effect. Moss is traditionally used in karesansui gardens to represent grass and water, but the substitution alters the representation to focus more on the arrangement of rocks and the natural patterns of the gravel.
