A friend has a neighbor that is letting me come pick up horse manure from her paddock. I have tubs and used most of the "older" areas and now am working my way into deeper and somewhat newer poo/straw. The manure is dark, doesn't smell too badly but I am hesitant about using these next batches directly in my gardens.
I have two compost bins in different stages of decomposition. Currently have no green material (other than kitchen scraps) but oodles of dead leaves. Can I effectively mix shredded leaves with the horse manure and layer that intermitently with the partially finished compost? I can't see it heating up much but I need to use the horse poo while I have access to it (farm is on the market).
