Mulching is the process of adding a layer of material to the soil around plants in order to improve soil health, hold onto moisture, regulate temperature, and prevent weed growth. Bark, compost, wood chips, straw, or grass clippings are examples of organic materials that can be used in addition to inorganic alternatives like gravel, plastic sheeting, or landscape fabric. https://texasgardenmaterials.com/landscape-design-houston-tx/mulch-delivery-installation/
