A good portion of my lot was meant to grow Christmas trees but they were never cut so now I have nearly 100 tall scotch pines.Obviously a lot of the inner trees have been choked out and are dead or dying and I have harvested a dozen or so into my piles but I never see anyone commenting on how well they burn. I haven't tried them yet because they are in the pile closest to the house and that pile won't get worked on until February when the other piles have become inaccessible.It looks like they rot quick so the bad ones just ended up in the brush pile.
