What is the function of mulch in landscaping?

The function of mulch in landscaping primarily revolves around its ability to inhibit weed growth. By covering the soil, mulch blocks sunlight from reaching potential weed seeds, effectively preventing their germination and growth. This allows desirable plants to thrive by reducing competition for nutrients, water, and sunlight. Additionally, mulch helps maintain soil moisture levels, contributing to a healthier environment for the plants. While some other functions of mulch might include moisture retention and temperature regulation, the most significant and widely recognized role is indeed in the suppression of weeds, making it an essential tool in landscape management.
