Hardscaping refers to the non-plant elements of landscaping, such as patios, walkways, and retaining walls. It plays a crucial role in defining outdoor spaces and enhancing their functionality while providing a visually appealing structure. Incorporating hardscaping into your landscape design can improve drainage, reduce erosion, and create usable outdoor areas for activities. Materials like stone, brick, and concrete are commonly used, allowing for a variety of styles and finishes that complement the natural environment.
