I have two backyard compost containers. One had a bunch of sawdust added to it by some workers at my place. It was awfully dusty in there so I watered it and mixed well. It was still dusty so more water and more mixing. Ever since, it smells pretty bad, like there's not enough oxygen in there. My theory is that it now has too much brown and needs more green. My friend Sarah thinks it needs more brown. I'd love to hear your compost stories and an answer, if you have one. Thanks!
