I have read up a little about osage orange fence. From what I understand, you need to plant them close together. In the fall, bend them down and stick the top into the ground. This will cause them to grow more vertical shoots. These vertical shoots are then bent down again but woven together this time, and then repeat with new shoots. At some point you allow it to grow, and trim it into a hedge. This fence will be made bull strong, horse high, and hog tight. Only down side is the constant trimming.
