I've always used hay, but hay has weed seeds. And, mostly because of the lingering herbicide in it (and until I can find hay that is NOT sprayed) I decided to try the shavings. So far, so good! I've run out of shavings so until I get back to town Monday I get to take a break. I wasn't sure how I'd like the look - but I'm ok with it so far. It's supposed to "darken" a bit with a couple of rains. I just really hope it helps keep the weeds down. I've spread paper feed sacks under it to help. Not sure how long it will take for the paper to break down, and then in turn, for the shavings to break down. But, time will tell.
