Mulch is a material spread over the soil around trees, shrubs, and other plants. It helps to retain moisture, suppress weeds, and regulate soil temperature. Mulch can also improve the appearance of your landscape and provide a habitat for beneficial insects.
There are many different types of mulch available, including organic materials like wood chips, bark, and compost, and inorganic materials like gravel and rubber. The best type of mulch for your needs will depend on the plants you are growing, your climate, and your budget.
