Harvesting Worm Castings

So, we've had the worm bin for about a year and I finally decided to take out the four inches of castings that are sitting in the bottom. I tried several ways but settled on removing all the large pieces of bedding, taking small handfuls of castings mit worms and placing them in a colander and shaking it gently to get all the loose castings out of the bottom. This way little pieces of newspaper, food, seeds, and worms don't end up in the castings. Then we can bottle it up in little spice jars and give it to people as gifts with directions to make "worm tea" for fertilizing houseplants. I love Christmas. :-)
