This particular pile was well over a year & a half. It was big. I have a plastic compost bin from the town- about 4 x 4. There are still scraps at the top, but when I lifted the side bottom panel, the stuff on the bottom was cooked. It's a dark brown bin, with a cover. My youngest daughter searches for big fat worms under our mulch after it rains & puts them in. I can't imgaine how many worms there might be in there...lol There were no worms at all in what I removed- they headed upward, I guess. Dang miracle, I tell you.
