How to Make a Berm for Landscaping
Flat landscapes work in some cases, but to add interest and elevation to a deaf appearing garden, add one or more berms. A berm is an area of mounds of land for planting. It can be added to the perimeters of the garden or in the center. Berms in unusual form add even more interest.
Large retaining walls allow more plants, possibly a central focus tree with shrubs around it. Small retaining walls work well for shrubs, perennials, herbs and much more. Be creative and design with your plants in mind.
- Make sure you have a list of what plants you want to grow in your berm (s). Find out what your mature size will be and plot a basic layout outlined for where you are going. Avoid overcrowding, both in your drawing and when to plant. For example, you do not want to put 30 bushes and 3 trees on a 6 foot by 4-foot berm.
- Request a load of soil for your garden or large shopping bags in sufficient quantity if making a smaller berm. You will have enough land to the Lomita at 1 to 2 feet in height for an average berm.
- Move loads from the ground trolley to the locations of the berm, adding enough until they have reached the approximate size. Experiment with length, sizes, and shapes that appeal to you. Add more soil than you anticipate for each berm as they are laid and flattened a little.
- Spread the soil and form the berm using shovels and rakes. Rake the top of the berm of something level and that the slope of edges naturally on the existing floor. Walk down the berm gently to help flatten it. Step back and see the berm on all sides, add more soil where necessary to fill the sunken areas.
- Lay potted plants in their previously sketched exit locations. You can alter the arrangement simply by moving the plants to get an idea of how they look at you when on the ground. Once you find a satisfactory design, dig holes of the right size for your plants, add the nutrients, fertilizer and install the plants.
A practical berm with rockery if you wish. Larger stones work best for large retaining walls, and smaller ones may not need any at all. This is simply a matter of design and maintenance. Some gardeners prefer to let grass or ground cover grow up and over the berm, under trees and shrubs. Finish by adding a garden ornament, such as a bird bath, sculpture or another interesting element.
