Walling and edging in landscaping encompass various elements crucial for effective design and implementation. Material selection is key, considering factors such as durability, suitability to the environment, and aesthetic appeal. Height and design of walls should align with functional needs, whether for retaining soil or defining boundaries, while maintaining visual harmony with the landscape. Edging specifications focus on delineating areas like flower beds and pathways, with materials chosen for ease of installation, maintenance, and longevity. Permeability for drainage, adherence to local regulations, and consideration of sustainability principles further inform the specifications, ensuring that walling and edging contribute to the overall coherence and functionality of the landscape.
