orange peels are AWESOME for the compost, I have at least 100 oranges worth in my compost, what I like to do (since i'm a fruit eatin monkey) is get brown shopping bags, and fill them with the trimming as I trim my herb (seems like i'm endlessly trimming) and as I fill the bags with cannabis leaves I alternate layers of the orange peels (like a min compost pile), them when they are half full I crumple up the tops, and bury them in my compost pile.
by the time I turn the pile they are already half broken down, the bags are already broken down, and the oranges are big ole globby fuzzy green moss.
sometimes I add banana peels in those bags as I trim too...
the worms don't seem to mind the oranges when they are like that..
as a "rule" they say citrus in the wormbin is a "no-no" but the worms seem to not mind that rule being bent a lil, citrus in the wormbin doesn't hurt em much, but the key is you want the peels on the way to decaying, so to add being fresh i'd think would be bad.
but I have added some fuzzy green orange peels to my bin before
you know what they are LOVING, is this leftover steer manure, I emptied my entire compost into a 250 gallon smartpot,(to keep the damn redwood roots away) and had a speck of room on top, so I emptied half the bag of this old manure I had on top of the compost, in the smartpot, to help keep the moisture in, and WOW.. those worms wen nutso, those are some bull-shit-eatin worms
gives new meaning to the phrase "shit-eating-grin"..
