Berms are a new way of landscaping gardens that I haven't seen too much of in the New Orleans area. I will break down the anatomy of a berm and you can decide if you can tackle such a task. If not, and you love the idea, then you can always call me to build you such an amazing specimen.
The berm in the pictures started with a patch of grass 35 ft. by 15 ft. First, I cut away the sod with a sod cutter and hauled that off.
Now that there was a large swath of empty space, I had to build up the foundation to begin our berm in the landscape design. And that, of course, requires a lot of sand and a ton of compaction.
So now that the berm is fully built, it is time to start adding plants. You might say, "oh, planting is easy. I'll just pick up some stuff at the Home Depot and it'll look great!" Before you get all gung-ho, let me bring you back to reality because for this giant landscaping project, we have chosen 1,000 plants and purposely placing every last one of them.
Hills can't take being pounded by rain without some support holding them up. Since there is no retaining wall in use, I had to build a living one, with the plants roots acting as a rebar system. So, I put the perennials with deep growing roots on the base corners and the ridge of the berm. I also added some nice sized chunks of limestone rock in the upper slopes for added support. The rock gives a natural look as well.
