Landscape Berms And Mounds

Berms are simply mounded hills of soil that are constructed to serve a purpose in a landscaped area. They can be used for aesthetics, excess rainwater drainage, separating different areas of the garden, accent walkways, and as foundations for privacy screens.

How do you build a landscaping berm?

To build a berm, outline its shape and dig up any grass. Next, add the desired fill to the excavated area and begin packing around it with soil. Then, continue piling on the soil, tamping as you go, until you reach the desired height. The berm should carefully slope outward.

What are landscaping mounds called?

Drainage Issues in Berms The use of a base of gravel or sand as well as drainage ditches can help alleviate such soil loss.
