As previously mentioned, unity and balance are essential elements for effective landscape design. Everything in your landscape, from the plants and shrubs to the landscape lighting and water features, should come together in harmony without feeling forced or constrained. Boundaries can be set almost imperceptibly, making proper use of pathways to separate key elements while making them still feel interconnected. Repetitive elements are sometimes used to bring that sense of cohesion, whether it be in the form of repeating colors, patterns, or plant species. Raised beds and concrete edge curbing can help define areas in your backyard or garden landscaping to make them more visually appealing. An eye for design and proportion is required to plant various flora without generating a sense of overcrowding, no matter how big or small the space.
