Well, IDK how they breakdown in the wild but (and this will sound gross) I had three valencia oranges on a fruits stand on my counter from last November until last week. They never rotted, molded or smelled odd. Heck, they didn't even get rock hard like I thought they would!
I guess it was the right blend of low humidity and temp.
Wow! Those are some special oranges!
I do have a couple in my fridge that my parents gave me from their tree... probably in March. They still look & feel good, but I'm askeered to eat them now...
When I compost, the stuff is getting mixed with all kinds of decomposing matter, plus worms and bugs are working on it, and probably other critters too, so I'm sure it decomposes faster than normal. I promise y'all I won't be throwing any orange peels on the side of the road! I'll save it for the pile at home...
On a tangent, has anyone ever used a composting drum? One of the ones you spin every day or so? I've often thought of getting one, and with all the wild animals around here scavenging for food, it's probably not a bad idea to enclose the scraps...
