I think so!
This morning I was checking on a section of one of my outdoor worm windrows (worm beds currently sitting over top of my vermicomposting trenches) where I had added a lot of “homemade manure” not too long ago, and was totally blown away by the number of worms concentrated in this zone. What’s interesting is that I added lots of “real” aged manure (aka “worm candy”) to these beds not too long ago (and yes, I’ve been meaning to write about it ever since – haha), and the resident worms (those that overwintered in the trenches, along with countless others that hatched out this spring) absolutely went to town on it. It was like a worm magnet! My point here is that they LOVE this manure…yet the homemade stuff seems to be even more appealing!
It didn’t always look that way though! When I first made it I ended up letting it sit for quite a few days in the garbage can I mixed it up in. This was great for rotting it down and getting the cardboard nice and soggy, but I think it also allowed it to go pretty anaerobic. When I first put it in the windrow (likely for the first 2-3 days) the worms wouldn’t go near it! Then all of a sudden they went crazy for it!
Anyway, I definitely think I need to do some experiments with this stuff!
