One of the benefits of worm composting is the worms’ poop which is very nutrient-rich compost. Vermicompost (the fancy name for worm poop) is really good for all indoor and outdoor plants and excellent to add to a vegetable garden. It will take around 6 months before you are able to harvest vermicompost for the first time. After that, you will be able to harvest a small amount every month or so depending on the size of your worm compost bin and your worm herd.
One way of screening worm compost is to build your own homemade cylinder harvester. For more ways to harvest worm compost read: How to Harvest Worm Compost: Learn 7 different methods for Harvesting your nutrient-rich worm poop!
Cylinder Spinning Harvester – If you have a lot of worm compost to process you may want to consider building or buying a worm compost harvester that is designed to separate the worms from the worm compost. Check out this video of me using the one that I built. The cylinder is made from 1/4 inch hardware cloth. Handfuls of worm compost + worms go in the top, as it spins the small chunks of worm castings fall through the screen while the large chunks and the worms come out the back. It works decently but it is certainly not perfect.
