Can kitchen wastes (like potato peels, onion skins, orange rinds, egg shells, tea inside tea bags etc) be used as manure? If so, how to use them?
Right now, I'm just dumping them in soil, which I feel is a wrong way to do this. Apart from looking like garbage, it takes a long time to degrade. I wonder whether they degrade at all, or just get buried in mud while watering.
Will it cause any damage to the plants? Is dumping them on soil considered okay? Or should they be treated in some way before dumping them on soil?
