A friend told me that you shouldn’t put potato peelings onto the compost heap but didn’t know of any reason for this. Is this correct? Answer … The only reason for not composting potato peelings is that they are a potential source of the fungus that causes potato blight. Blight spores can survive only on living plant material. Potato peelings can provide this when the buds in the eyes of potato skins grow into potato plants. To ensure that the peelings don’t sprout, bury them well down in the compost and ensure that you turn the heap regularly. If you do this, it is fine to compost the peelings. https://www.gardenorganic.org.uk/faqs/potato-peelings
