It depends on why you are using it

Most types of mulch take a few years to break down and decompose. How much you use-and how often-depends on why you are using it.

  • If you are just looking for aesthetics, maintain at least a 1″ layer of mulch over your native soil.
  • If you are also trying to suppress weed growth and want your soil to retain more moisture, we recommend maintaining a 2-3″ layer of mulch around your plants.
  • Always make sure to leave a little space around the stem base of bushes or tree trunks. This prevents rotting and allows your plants to get more oxygen.
