Soil erosion around a home foundation is simply as much an issue for homes on flat land since it is for homes on slopes. Each individual’s garden area is going to have a completely different soil structure. If the region that you tested for garden drainage is a comparatively modest area, you are able to still use the area by choosing plants that could tolerate loads of moisture.
Common rough gray gravel employed in under-layment and driveways is known as quarter-minus. Smaller drainage issues can be handled with a trench that’s 5 to 6 inches wide, while larger problems will take a bigger trench. Rock gardens require maintenance, so begin with a size that’s easily manageable.
