Any advice on how to rectify my compost heap. Firstly the grass I used was old grass which was just lying in a heap so I incorporated this with some manure, twigs, fruit & veg and paper into my compost heap. It is very wet so I am going to add a lot of paper, and cardboard. Is it possible to rectify my earlier mistakes, old grass and not enough paper. I don't mind waiting a few years in order for it to decompose so long as I am not wasting my time. Any advice appreciated.
