There are literally thousands of hedge posts in this area. I have set alot of them, pulled a fair amount and burnt a bunch of old ones at hog roasts, but I have never seen one that turned green. Two years ago I had one that had been in the ground 40+ years, then laid in a post pile another 10 or so. A friend that makes custom knives wanted some wood for knife handles so i cut him some out of that post. The wood was just as hard and dense as the new stuff. Once those post age about five years, they get so hard you can't drive a staple in them! George is right, hedge is EXCELLENT firewood, heat our house and fur shed with it.
