Steps to make compost

  1. Place bin in a strategic spot
    For best results, place your bin in a level, well-drained, partly sunny location.
  2. Create base layer
    Add approximately 6 – 10 cm (3 – 4 in) of leaves, straw, or twigs to the bottom of the bin. This allows air to circulate and encourages proper drainage.
  3. Add materials
    Add a mixture of green and brown materials. Greens are quick to rot and provide important nitrogen and moisture. Browns are drier, provide fiber and carbon, and allow important air pockets to form.
  4. Mix bin contents and regulate moisture
    Mix bin contents every 1 – 2 weeks. Mixing adds air and distributes moisture and heat which help speed up composting. Bin contents should be like a wrung-out sponge. Mix the contents to determine the moisture content. If compost is too wet, add more brown materials; if it is too dry, add some green materials.
  5. Use compost
    The composting process usually takes 3 – 9 months. Finished compost is the dark brown, almost black soil-like layer found at the bottom and center of the bin. Remove the door or lid and use a shovel to remove your compost. Spread the finished compost on your garden beds to retain moisture, add nutrients, and suppress weeds.
