About 120 days ago I emptied my compost bin and put about a yard and ahalf of rich, black compost into the vegetable garden. That was satisfying, but it was a bit discouraging looking at that bin and thinking "man, how long will it take to have compost again?" Well, last weekend I sifted two full garbage cans and a full wheelbarrow of rich, black compost from that bin and I have a new batch started. All from kitchen waste and yard trimmings. It's easy and cheap, and the effect of good, fresh, rich compost teeming with microbes is really fantastic.
