How you harvest castings.

There are a number of different ways to harvest your bin once you are ready.
First of all it depends on the size of your bin. My bins are 4'x 8'. In a bin this size I am able to split out one end and reserve it for finished material. I have the bin marked off in 6 parts. I pull all the "fresh" material off the top from part C - F. If your bin is working as it should be, then the majority of your worms are going to be up in this fresh material feeding. (There are things you can do to make sure most of the worms are in the top layers.) I have one end of the bin empty (A & B) so I have a place to put the finished material I will pull from the bottom of the bin. The top portion you pulled off to begin with then goes back in the bin and the space left from the finished bottom layer being removed leaves you room to start adding more fresh material on top. The finished material will rest in the end of the bin, get turned to help it start to dry out and whatever worms are still in it will continue to work the material until they decide to move back into the other end of the bin or die.
With a smaller bin I would have a second container for a holding bin. The process would still be the same. Take the fresh material off the top, move the finished material into the holding bin. Add the fresh material back into the composting bin. The finished material will need to be turned periodically to help it dry out. The worms left in the finished material will continue to work until they die.
