Berm Plants and Cover Products
Please guide us for correct steps, plants and ground cover to use for berms we want to plant. The area in mind is on the north side of our house. We are Zone 5b, southeast Colorado. Currently we have two rows of Pinon trees on north edge of grass, east side is wide open to alfalfa field, west side is basically open too. South side is the house, space is about 40 feet north to south and 100 feet east to west. We'll be replacing the grass at some point in this area, but for now we want interest and plantings. Never made a berm, have wild bermuda infringing on the grassy area we have and HOPE to stop this. Sure don't want it up in the berm, so steps to prevent this is a MUST as well. We have one 2 year old red maple located on east end and also on the west end of grass edge. Otherwise, no trees to block light.

Nearly anything you want can be planted in the berm, as long as it's suited to your area and specific growing conditions. I would recommend pouring boiling water on the areas where the bermuda grass was growing. Boiling water will kill whatever it comes in contact with.
