I don't yet have a worm bin for my garden, but what I do have is a mealworm bin for my hedgehog, who enjoys the little things more than anything in the world. Does anyone possibly have any experience with mealworm poop? I've about five gallons of the stuff right now, a very fine grey powdery material, and I'm wondering what the hell to do with it.
UPDATE: I did some digging! Insect poop is called "frass" - and according to wikipedia
http://en.wikipedia.org/wiki/Frass - "It causes plants to excrete chitinase due to high chitin levels, it is a natural bloom stimulant, and has high nutrient levels. Frass is known to have abundant amoeba, beneficial bacteria, and fungi content. Frass is a microbial inoculant, also known as a soil inoculant, that promotes plant health using beneficial microbes. It is a large nutrient contributor to the rainforest, and it can often be seen in leaf mines."
-From a site on setting up mealworm bins for your birds - "Mealworm frass is an exquisite plant fertilizer – indoors and out. We do, however, recommend not having it on the top of the soil for indoor plants as watering it will enhance its odor. Otherwise, we’ve not met any kind of plant – leafing, flowering, or fruiting - that doesn’t love mealworm frass."
-Someone did an article about it over at another growing site, but I'm not sure on IC's rules about posting links to other grow forums, is it allowed?
-I've found frass for sale from hydrostores online. It's suggested that frass A)Kills fungus gnats, B)kills root-feeding nematodes, and C)It contains, and I don't know how believable this one is, I hope microbeman stops by "6+ TRILLION cfu/gm(Is gm a typo there? Do they mean g?); no other biologic source comes close - 100 Billion Fungi spores per gram"
If any of those claims are true I've some awesome stuff on my hands!
Since the mealworm bin needed cleaning anyway, I might as well save the frass. Apparently frass is made up of eggs and poop, so I will have to save it for a couple weeks with some oats, let the larvae hatch, and then sift them out. After that though I should have a bucketful of frass!
Unfortunately I'm not growing that wonderful good green(for a variety of reasons) right now, but I'm going to try a side-by-side with some tomatoes indoors, and then a side-by-side out in the main garden. It's a start to figuring out the effect this stuff will have. The worms will be here regardless, but if I can get a fertilizer out of them as well they're paying their way twice.
