Cedar mulch is also known as a natural pest controller. According to GreenNature.com, cedar oil is a natural insect repellent; however, fresh aromatic cedar mulch will repel pests better than mulch that has been exposed to elements over time.
Cedar mulch should survive for several years; however, it is recommended that gardeners add mulch every year in order to maintain color and beauty of the mulch.
Non-toxic dye is added to the cedar bark, the dye remains bright for only about one year. Colors generally are available in red, black or brown.
Cedar mulch will not harm plants since it does not mix with the soil and decays slowly. Cedar mulch is completely organic and non-toxic.
Follow directions located on the package of mulch. Directions normally suggest applying a 2- to 3-inch layer of cedar mulch to the area. According to SBCCedar.com, a 56 L sized bag of mulch should cover approximately 8 to 12 sq. feet.
