Put in grass clippings, leaves, kitchen scraps, tea bags, used coffee grounds, egg shells and veggie/fruit scraps in it. Put the composter in the shade in your yard or balcony, keep it moist but not wet. Some worms will help it immensely. Especially red wigglers -ordered through your local gardening center or compost association. Put in about 2 lbs of worms. In about 4 months you should see a nice rich, dark earth. Scoop some out, sift it and top up your houseplants or outdoor plants with a couple of handfuls.
