Worm Harvesting

This is an email I recieved about worm compost way too wet for separation at harvesting time:

I just purchased one of your worm harvesters and I am anxious to use it. I teach second grade and I keep my bin in my classroom. My kids help to manage the bin. I really would like them to begin harvesting the compost using the harvester worm poop is very wet and not dropping through the screen. I know you suggested drying it a bit but exactly how do I do that? I find when I have dried the compost it dries in hard clumps.
How do I create light, dry, loose compost and castings. We would like to sell it at school as a fundraiser but I want it to be just right.

Thanks for your help!


Your material is way too wet I think. Here are some ideas. Tear newspaper into chunks (not shredded). Mix it into the material well until wet then remove. Do this several times with new paper each time. You should be able to absorb a lot of moisture this way.

The material should be more manageable after this. Now put the material on a tray with shallow sides (to keep the worms in) and run a fan on this. Periodically run your hands through this to break up clods and stir the material so that it all dries evenly. Soon you should have harvestable compost.

I hope this helps. The kids will get such a kick out of harvesting time :o)
