Not to ask a dumb question, but I am assuming pine straw is just the needles off of pine trees. How do you bale it, and what is it used for? I have large pine trees on the back side of my house, and each fall the tree deposit 4 inches of pine needles onto the roof and gutters. I was just up on my roof a couple of days ago blowing the needles to the ground, and then I mow them up and get rid of them.
