The answer to 'which is better retaining wall or' is that both retaining walls and landscape edging have their own benefits and use cases. Retaining walls are better suited for managing steep slopes, erosion, and large elevation changes, while landscape edging is more appropriate for defining garden beds, creating clean borders, and separating different landscape elements.
Retaining walls are typically made of concrete, stone, or interlocking blocks and are designed to hold back soil and prevent it from eroding or sliding down a slope. They can be an effective solution for creating usable outdoor living spaces on sloped properties. Landscape edging, on the other hand, is a more decorative and functional element used to outline garden beds, walkways, and other landscape features. It comes in a variety of materials like plastic, metal, wood, or stone and helps to keep mulch, soil, and plants contained.
