The Preferred Food Of Detritivores: A Composting Project
Difficulty of Project
Red wiggler worms are the lion’s share of the cost here. If you can find them locally, be prepared to spend about $22 for a lb, although you will likely not need that many. Many plant nurseries will sell them for about $10-$14 for approximately 300 worms- more than enough. The bonus about doing this project is that much of what you need in the project can be used to set up your own vermicomposting system at home afterwards, and all the other components are recyclable!
Always wash hands after handling both worms and composted materials.
