What is the function of mulch in landscaping?

Mulch serves several important functions in landscaping, with its primary role being to conserve moisture in the soil while also suppressing weed growth. When applied to the soil surface, mulch acts as a barrier that reduces evaporation, helping to retain moisture during dry periods. This is particularly beneficial for plants, as consistent moisture levels contribute to their health and growth.

Additionally, mulch blocks sunlight from reaching the soil surface, which inhibits the germination and growth of weeds. By reducing competition for nutrients, water, and light, mulch ultimately supports the growth of desirable plants.

While mulch can influence soil temperature and improve soil structure over time, its main benefits revolve around moisture conservation and weed suppression, making it an invaluable tool in effective landscaping practices.
