Dry stacked rock walls are typically built against a hillside, as it can be used as a tool to prevent soil erosion from ruining a garden [1] X Research source
Each type will give your wall a different look and feel, so make sure you look at pictures to determine which would be the best fit for your house and landscape. Note that flatter stones tend to be easier to work with than rounder ones, as they are more suited for stacking.
Freestanding dry rock walls can be stable if they are up to three feet in height[3] X Research source
Try to cut the ditch into native soil rather than loose added soil, as the former provides a more stable foundation for the wall. Level the foundation trench. Smooth over the ground beneath your wall with a shovel, and line it with crushed stone pieces called stone screenings, stone dust or fines. This material will also be useful for filling in gaps.
Avoid large vertical gaps in your wall. Try to rearrange the stones so that those don’t appear.
