An Alternative to Weeds
Most natives cannot compete with weeds, and therefore must be weeded around constantly in order to thrive. Mulch is a practical alternative, which discourages and prevents weeds from growing.

Use Thick, Organic Mulches
Hawaii's hot, humid climate leads to the breakdown of organic mulches. However, thick organic mulches such as wood chips and leaves also make good hiding places for pests. Stone mulches are attractive, permanent, and can help to improve soil quality. Natural choices include:
  • Red or black cinder
  • Blue rock chips
  • Smooth river rocks
  • Coral chips
Other Useful Information
Macadamia nut hulls are also easy to find and can make a nice mulch. Never pile up mulch right next to the stem or trunk of a plant, keep it a few inches away.
