Add initial layer of waste including twigs and branches for air circulation. Layers should be 6 to 12 inches deep.
Add Compost Starter – one cup for 16 square feet of layer area.

Tips and Suggestions

  • Reducing the size of waste by shredding will speed the composting process.
  • Any organic waste can be composted including kitchen scraps, leaves, grass clippings, etc.
  • Composting meat scraps may attract animal pests.
  • If you experience problems, these can often be addressed by adding Compost Starter and turning the pile.
  • If you notice a foul odor, the process has turned anaerobic (not enough air). Turn the pile more often to allow air to penetrate the center.
