What is the primary reason to use mulch in landscaping?

The primary reason to use mulch in landscaping is to suppress weed growth. Mulch creates a barrier that blocks sunlight from reaching weed seeds, thereby reducing their germination and growth. This helps maintain a clean and attractive landscape while allowing desired plants to thrive without competition for resources. Additionally, mulch can help retain soil moisture and regulate soil temperature, which further supports plant health. While it does offer benefits related to soil texture and can contribute to ecological functions, its most prominent role in landscaping is effectively managing weeds, making it easier to maintain gardens and landscapes.
