My erosion bundles (see here for details) have been outside for just over two weeks now. Snow didn't materialize here, but it has been cold and yesterday's rain deposited leaves and some dirt on my bundles.
I don't notice much if any change yet. It occurs to me that I may end up with — ewwwww — a bunch of mold. For those of you who are following, here are pictures of the three bundles: Art, Phoenix, and Canvas, as they looked this morning.
