Living Retaining Walls: What are They and How Do They Work?

Living retaining walls are a type of landscaping feature that combines the functionality of a traditional retaining wall with the beauty of living plants. These walls are designed to hold back soil and other materials while also providing an attractive and natural-looking addition to any outdoor space.

Living retaining walls are typically made from a combination of soil, rocks, and plants. The soil and rocks provide the structural support for the wall, while the plants help to stabilize the soil and add visual interest. The plants used in living retaining walls can vary depending on the desired look and function, but typically include shrubs, grasses, and other low-growing plants.

The main purpose of a living retaining wall is to provide stability for soil and other materials that would otherwise be prone to erosion or collapse. These walls can be used to create terraces or steps in a sloped landscape, or to hold back soil in areas where it would otherwise be prone to sliding or shifting. Living retaining walls can also be used to create attractive borders around gardens or other outdoor spaces.

In addition to providing stability, living retaining walls can also help to reduce noise pollution in urban areas. The plants used in these walls act as natural sound absorbers, helping to reduce noise from traffic or other sources. Living retaining walls can also help to reduce air pollution by trapping dust and other particles before they enter the atmosphere.

When designing a living retaining wall, it is important to consider the type of soil and plants that will be used. Different types of soil will require different types of plants, so it is important to choose plants that are suited for the specific conditions of the area. Additionally, it is important to consider the size and shape of the wall, as well as any drainage requirements that may be necessary.

Once the design of the wall has been determined, it is important to properly install it. This typically involves digging a trench for the wall and then filling it with soil and rocks. The plants should then be planted in the soil and rocks, with additional soil added as needed. It is important to ensure that the wall is properly secured with stakes or other supports so that it does not shift or collapse over time.

Living retaining walls can provide an attractive and functional addition to any outdoor space. They can help to reduce noise pollution, air pollution, and erosion while also providing an attractive border or terrace for gardens or other outdoor spaces.
