Potato Peelings and Skins are a great addition to the composter.
Some people may be worried about potatoes sprouting in the compost. This can start to happen if you are adding whole potatoes or large pieces of potato. However, if there is sufficient heat in your composter, the heat will kill off the sprouting potato shoots.
This problem will not happen if you are just adding potato skins or peels. They will decompose quickly without sprouting.
