Scale plays a crucial role in establishing compositional harmony within a landscape garden. When planning a garden layout, it is essential to consider the proportions of various features in relation to each other and the surrounding environment. Larger elements, such as trees or large sculptures, can create a sense of permanence and stability. In contrast, smaller plants and decorative objects can provide visual interest without overwhelming the scene. Striking a balance between these different sizes ensures that no single feature dominates the space, allowing for a more cohesive design.
