The balled up castings that did not make it through also get returned back into the worm bin. I then pick the worms out and return them back to their bin. I put some castings in from the bin into the sifter and rock it back and forth over a plastic tote that will catch all the castings that fall through.

But the plus side is that I can quickly get the castings I need. The down side so far is that more worms make it through the screen than they did with the metal wastebasket version. Some castings still ball up, but no where near as many as the other method mentioned above. The holes in this sifter are a little bigger and allow most castings to fall through easier. I am not going to retire it for those days when the castings are dryer in the hot summer days, but I did create another quick, inexpensive alternative to sifting the castings. Since my worm bins have been a little more moist lately, that tumbling process has not been performing as well now as it did when I first created it. For the most part, I have found that it still works great for me, but the castings do need to be a little dryer than usual for them to properly filter through the screen, otherwise they start balling up during the tumbling process and you don’t get as many castings. Some people say the holes are too small since they are only about an ⅛”. With the busy lives we all seem to live these days, we all desire quick results.īack on December 29, 2017, I wrote about a Worm Casting Harvester that I made from a metal wastebasket (Check out the post here: ).

I ask the same question myself all the time. This seems to be a question I see a lot through Facebook groups/pages and other websites on worm composting. “What is a fast and easy way to collect worm castings?”
