Wood Chips as Mulch

I am more than half way finished with spreading the wood chips in the beds at the front and side of the entrance to my cottage. I have weeded this area so much that the soil level has gone down at least 4 or 5 inches. I got a free load of wood chips after hurricane Irene and they are perfect for spreading because they have aged to a nice brown color. My goal is to have neat beds with boxwood and whatever hardy perennials come back on their own. So far, so good. I see some Ladies Mantle. I hope the rest of it comes up even though it's buried below the chips. It's survival of the fittest around here. My plants are in the Army now.
