Mulch comes in many forms. Some mulch is made from organic materials, such as chipped and organically treated wood. Other mulches are made from inert materials. The one that is right for you will be based on your flower beds, the scale of your landscaping, and your personal preference.
Mulch helps a flowerbed in several ways. It helps prevent fugitive weed seeds from gaining a foothold. It also helps with moisture retention and moisture consistency throughout the soil layers. Not to mention it is also more visually appealing than bare soil.
There are several types of mulch to consider. The one that is right for your landscaping will depend on several factors, including your personal preference for aesthetics and material use.
