  • Mulch should be applied on the surface of the BMP in a layer of 75 -100 mm.
  • As in other landscaping applications, the mulch helps to preserve soil moisture for plant survival, and suppresses weed growth.
  • Mulch is considered to be an normal finishing touch to many types of formal landscaping. Maintaining mulch application can help increase aesthetic value of LID BMPs.
  • Shredded hardwood mulch is recommended. Its fibrous texture knits together somewhat; providing erosion control on the surface of the BMP.
  • Regular fresh applications of wood mulch also promotes denitrification, reducing nitrates in impacted surface waters.
