Mulch is a material, usually organic, that is spread over the surface of soil to improve its fertility, appearance, and ability to retain moisture. It is also used to suppress weeds and control erosion. While mulch has many benefits, it can also have a negative impact on your nose if it smells bad.
Bad-smelling mulch is usually the result of anaerobic bacteria breaking down the organic matter in the mulch. This process can produce a variety of foul-smelling gases, including hydrogen sulfide and methane. The good news is that there are a few things you can do to reduce the smell of your mulch.
