Frequently Asked Questions
How deep should a berm be?
There are many ways to create berms, and each one can vary in size and can have more than one peak. Berms can be as deep as your customer desires, but typically, they are no taller than 18-24 inches.
How much dirt do I need for a berm?
The volume of the dirt in the berm is the area of the triangular cross section, times the length. The area of a triangle is one half of the length of the base, times the height which in your case is square feet. Thus the volume of the berm is 64 imes 100 = 6400 cubic feet.
What do you use to build a berm?
Build A Berm Or Landscape Mounds Berms are often constructed using fills such as plant debris, sand, asphalt, soil, or rubble. Use the fill materials to fill the major part of the berm, forming its shape around it using the soil. Firmly tamp the fills to ensure compactness.
How big does a berm rock garden need to be?
A berm is a type of raised garden with informal edges. This style of rock garden is often used on relatively level sites. Freely draining rock garden soil is mounded at least 12" above grade. Rocks of different sizes are then placed and partially buried along the berm.
What kind of soil to use for berms?
To save money, use topsoil as a top layer (it is great to grow your plants in), but use clayey soil as a second layer, not a fill such as gravel or rubble. Clay is a type of soil more impervious to water than is fill, so your topsoil won’t percolate through it. Underneath the clay, use fill to build up the bulk of the base.
Why do you need a berm in your garden?
Landscape mounds, also known as berms, improve drainage in soil and raise plants to provide greater privacy in flat garden spaces. A berm is suitable for a rock garden or drought-tolerant plant bed, and it gives plants that well-drained soil to grow in.
