For about two years, we've been piling kitchen scraps (coffee grounds, egg shells, and raw fruit and vegetable trimmings), almost daily, and dead leaves, when available, into a 4' x4' pile on the ground in one corner of our garden. We cover the scraps with soil from the bottom of the pile about once per week, and the kitchen scraps are gone within a month. The material created seems like good compost to me . . .
however, a class I recently took said that you have to carefully balance the amount of grass clippings with dead leaves and kitchen scraps. According to this method, I've been putting in too much kitchen scraps. Will lack of brown matter make my compost a lower quality? Is my compost missing something it needs?
Thank you for your help!!
