I started a large compost pile at the beginning of last summer. i made a large bin out of pallets and it is almost full now. there is about a foot of space left, maybe a couple inches more. i am planning on covering the pile with several layers of newspaper and then filling the top in with garden soil and planting it. most of the compost has been in there over winter and has already shrunken down(it was over full) just wondering if this is going to work or not. has anyone grown like this before?
