re: Worm Farmin'

To harvest the castings when the bin gets full I separate the worms and undigested food out. The food goes in my overflow bin. The worms I separate by hand. You can make a sifter with a wood frame and screen of some sort on the bottom. Sometimes I lay clear plastic on the ground and put the castings in piles on it. The worms run to the bottom to get away from the light. It makes it easier to separate them. The worms I harvest go in my overflow bin which goes into the rotation. The bin I emptied becomes my food overflow bin. I enjoy the worm bins and it keeps a lot of food out of my sewer line. It really helps with keeping my ancient main line going.
