Steps

1
Select a sunny location on the ground to allow earthworms to access the pile. Ensure the area is level and close to a water source.
2
Begin building the pile by layering materials. Start with a coarse base of brown materials to prevent matting and improve airflow, then alternate layers of greens and browns.

3
Incorporate a handful of garden soil or finished compost into the new pile to jump-start the process by introducing beneficial bacteria.
4
Water each layer as you add it. The mixture should be moist but not soggy, maintaining a consistency similar to a wrung-out sponge.
5
Ensure the pile reaches a minimum size of 3 feet wide and 3 feet tall to effectively retain the heat necessary for decomposition.

6
Aerate the pile by turning it with a garden fork every 7 to 10 days. If using grass clippings, turn more frequently (daily for the first two weeks) to prevent the material from matting into anaerobic sludge.

7
Monitor the internal temperature. A healthy hot compost pile should ideally reach between 130°F and 160°F.
8
Verify the compost is finished when the pile has shrunk in size, the original materials are unrecognizable, and it has a dark, crumbly texture with an earthy aroma.

Pro Tips

  • Avoid adding meat, dairy, fats, or oils, as these attract pests and create foul odors.
  • Small particles decompose faster; shredding or chopping large materials before adding them can expedite the process.
  • Keep an excess supply of brown materials (like cardboard) on hand to add if the pile becomes too wet or smells of ammonia due to excess nitrogen.
