You'd think that someone who does a blog about composting would have the perfect composting system but I don't. As you can see in the picture some sort of critter (probably a raccoon) was able to rip through one of the screen covered air holes on my homemade compost tumbler and have a snack.
A well maintained compost pile should have no odor. I tell people that all the time. I have added that sentence to many of my posts. I wouldn't be surprised if my wife told me that I repeat it over and over while I sleep. Well I should pay more attention to myself.
You see, I added a ton of kitchen scraps to the pile over the weekend including eggs shells and green onion scraps. Now if I took my own advice I would have added more leaves to the bin at the same time and maintained the proper green:brown ratio. But I didn't. I didn't even roll the can around to mix the ingredients. I don't know why I didn't get to it. I was probably busy making green onion quiche or something.
After cleaning up the mess (and I'm lucky that it's a pretty small mess) I covered up the busted air hole and added about six inches of shredded leaves to the can. Then I gave it a good blast of water from the hose and rolled it around to mix it. The tumbler doesn't smell anymore and I've learned my lesson.
If you live in bear country or just don't want to worry about pests at all then I suggest sticking to mostly leaves and coffee grinds. You'll still get a nice compost and it shouldn't attract any attention from four legged friends.
