Adding mulch to your garden will improve the health of the soil and beautify the appearance of your landscaping.
Cover garden beds with a layer of mulch to keep weeds down and reduce the need for water. Annual weed seeds are less likely to sprout when the soil is covered with enough mulch to keep the soil surface in the dark.
When it comes to water, even a thin layer of mulch (nature’s moisturizer) will reduce evaporation from the soil surface. Thicker mulches can reduce water use by as much as 50 percent.
