The magazine is copyrighted, but I can summarize the article in a few sentences.
I have cut several Osage trees on one property over the last 8 years. As the stumps produced sprouts, I spent a few minutes each summer stripping new twigs off the lower parts of the sprouts--working higher as the sprouts gained height. A few of those sprouts are now about three inches in diameter, are straight and have no branches for the first six of seven feet.
