things to put in vermiposting/ composting piles:
anything uncooked, fruit or vegtable. egg shells are ok, but avoid meat (and milk) my brother has some tubs with the red wiggler variety, they are eating newspaper and what ever veggies he throws in there. carrots and potatoes help if you shred them, if you really want to feed them
I've heard the worms get in bunches to procreate, and if you are worm composting you don't really need to turn your pile (it also disturbs the orgy) water all you want till the worms start to float to the surface, then water 20% less
avoid citrus, it doesn't really do anything
