What is the role of mulch in landscaping?

Mulch plays a crucial role in landscaping primarily by retaining soil moisture and suppressing the growth of weeds. When applied as a cover over the soil, mulch acts as a barrier that reduces evaporation, helping to keep the soil moist for longer periods. This moisture retention is particularly beneficial during dry spells or in areas with high temperatures.

Additionally, mulch effectively suppresses weeds by blocking sunlight from reaching the soil surface. Without sunlight, weed seeds are less likely to germinate and grow, which helps maintain a clean and visually appealing landscape while reducing the competition for water and nutrients between desirable plants and weeds.

While mulch may have some indirect benefits related to soil fertility and attracting beneficial insects, its primary functions center around moisture retention and weed suppression, making it an essential component of effective landscaping practices.
