During last years harvest we wrapped our 4x4 round haylage bales with 20 wraps. We ended up with more mold than expected when we went to feed them this year. We were wondering how many wraps others have used and how successful you were with keeping mold out of the bales. No holes were visible and yet mold penetrated to the center on some and was only on the outside on others. We are located in Western Washington. Thanks in advance.
