During my 5+ years of vermicomposting, I have found that they love pumpkins. In the past, I have halved and quartered pumpkins and tossed them into the worm bins. After a day or so, I checked on them and lifted a piece of the pumpkin and to my surprise, I found a cluster of red wigglers underneath! Way cool!!!
If you have a worm bin and pumpkins left, go ahead and feed them to your worms!
Thanks to all of my friends for supplying these nasty, rotting pumpkins!
