We live in very wet western NC. We are getting rain darn near every day right now and we just had a problem where the drainage behind the barn that usually goes around the barn changed paths and was in fact running into the barn. So needless to say we had about a inch deep two foot wide puddle in the barn. We think we can get that to never happen again, but all of our hay in the barn is starting to mold as well as the sides of the hay rack and a couple other wooden thing we have in the barn. What should I do to clean everything off? We have struggled with hay molding in the past, but only after it sat in the barn for a long time. This hay was only in there since the beginning of the month. I think it probably had to do with the flooding, but I am not sure it hadn't started before that. We had put this last round on three layers of pallets to help it get off the floor, but that didn't help as even the very top of the stack had mold on it. I know that increased airflow is probably necessary, but without electricity in the barn and not enough sun to power anything solar, I fan is probably not an option. Maybe I just need to store my hay somewhere else? Any tricks for hay storage I don't know about? Sorry this is kind of long already, but one more thing. How does it work to store hay under tarps outside if there's no air flow under there?
