This may be a stupid question, but I can't seem to find an answer online.
I've read that, depending on various factors, it will take anywhere from weeks to months for
compost to "finish."
Ok, that's all well and good, but how does that work if you're constantly adding new material to your heap? Take a typical suburban composter such as myself; won't I be adding new material (kitchen scraps, fallen leaves, grass cuttings, etc.) weekly, if not daily? So won't there always be "new" material in my heap that isn't broken down? (assume I'm just using a basic bin or tumbler, and not vermicomposting) In that case, it seems like the compost will take forever to "finish."
Perhaps I'm over thinking this, but do you see what I'm getting at?
