I always add kitchen waste to my compost piles (veggies, coffee, grounds, egg shells etc.) but can I also add potato peels and lemon/orange peels? Is there anything in the veggie family that you shouldn't add? I've heard you shouldn't add onions. Is that true? Thanks in advance. :O
Yes add the potato peels and the citrus. Just be prepared to pull a lot of sprouting potato vines. I have read not to add to much citrus if you are growing worms in the compost, but other than that I know of no reason not to add all you have. It does take a long time for both potato peels and citrus peels to decompose, but they do.
I have found that dry onion skins are more of a dry "brown" than a wet green, so they take longer. Also peach, plum, cherry type pits don't break down for me. And I'm still finding dry peanut shells at the bottom of my pile.
