First time poster here, so I apologize if I get anything wrong here. Out of curiosity, I am wondering if anyone else is doing something similar to what my mother is dong. She has some raised garden beds with flowers in them (she doesn't grow fruit of vegetables), where the soil has started slumping. As she doesn't want to go out to buy any commercial soil or compost mixes to build the soil back up, she has started to put kitchen scrapes into the paper supermarket shopping bags and once full, place another supermarket paper shopping bag over it inverted, to make it harder for birds and animals to get into the scrapes, then puts it onto the raised garden bed without burying it.
