I’d suggest dump the chips now, disk them in, then over seed with annual ryegrass(the cheap cattle feed stuff not the improved varieties for lawns. That ryegrass will grow like gangbusters in the corner of a trailer, gravel, wood chips, anywhere. Put a little N on it a couple weeks after germination. Let it go all winter and into spring. You should have a lot of green manure from that come March/April. Cut it and let it lay. Put some clover down then if you like.
