What is one of the primary benefits of using mulch in landscaping?

Using mulch in landscaping primarily helps to reduce soil compaction and erosion. Mulch acts as a protective barrier on the soil surface, which slows down water runoff during rain, thereby minimizing erosion. It also helps improve soil structure by preventing compaction caused by foot traffic or heavy rain. The presence of mulch can continue to protect the soil, promoting better infiltration and helping to maintain moisture levels.

This benefit is significant in maintaining a healthy landscape ecosystem, as reducing erosion supports the stability of plants and prevents the loss of topsoil, which is essential for nutrient retention. In contrast, while mulch can have some influence on factors like soil acidity and nutrient availability, its main role is in protecting the soil and aiding in moisture retention and aeration, making it a vital tool in sustainable landscaping practices.
