Yes, landscape fabric is highly effective on slopes and hills, where its primary role is to provide erosion control and soil stabilization. When installed correctly, the fabric holds the soil in place and prevents heavy rain from washing it downhill, which is a common problem on steep grades. It also helps stabilize the cover material, such as mulch or decorative rock, by giving it a surface to "grip" onto, preventing the mulch from sliding or washing away.
For sloped applications, it's essential to use high-quality, professional-grade fabric and secure it carefully with an ample number of landscape staples to ensure it stays in place. While it will help stabilize soil and reduce maintenance, steep slopes may still require reinforcement with plants or retaining structures.
