The answer to 'retaining wall vs' is that retaining walls and landscape edging are both effective ways to define and contain landscaping areas, but they have different features, benefits, and use cases. Retaining walls are sturdy structures built to hold back soil and prevent erosion, while landscape edging is a more decorative border that helps separate and define garden beds, walkways, and lawn areas.
Retaining walls are typically made of concrete, stone, or interlocking blocks and are designed to withstand the pressure of sloped or uneven terrain. They can be used to create raised garden beds, terraced landscapes, and to stabilize hillsides. The main benefits of retaining walls are improved drainage, erosion control, and the ability to maximize usable space in a yard. However, retaining walls can be more expensive to install than landscape edging.
