How much aged manure can I use in my raised beds? I have four new huge raised beds, 16X 8 X 12 and it's going to cost a fortune to fill them with dirt. I have an almost unlimited supply of aged manure, not mixed with anything. It's really aged, at least 5-6 months old and I put a bunch in my other two gardens which are thriving with it. Just wondering if I could go as much as half or there quarters manure and get away with it?
Also, what's the cheapest place to get some soil delivered to Mesa? It doesn't need to have any compost in it since I'll be mixing my composted manure into it.
