Perhaps some pointers about composting are in order, particularly that there should never be any animal products like meat scraps, cheese, or gravy in the compost bins, and if you are a meat eater you can probably forget about doing this. Although you can compost coffee grounds and any outdoor yard waste. Outdoor composting bins will attract city wildlife like opposums, racoons, and rats whether you want them or not, so they have to be secure. Mixing compost with some good rich garden soil is a way to get those worms working and speed up the process of making dirt.
