Rock Garden Design on a Slope: Seek Professional Help for Layout

A 30-degree slope, 70×5 ft, demands structural expertise. Rock placement must be stable, drainage engineered, and plants chosen for microclimates. This is not a DIY design project. Hire a landscape architect or designer with rock garden experience. They will create a construction plan, specify stone sizes, and select plants that thrive in your Zone. The fee ($1,500–$3,000) prevents costly failures.
