Jives,
I am both intrigued and surprised to hear you are experimenting with Osage Orange trees. I live in Northern Kentucky and these trees are prevalent. When I bought 7 acres adjoining my existing 5, all hillside facing west, the land hadn't been bush hogged for four years. There were over a hundred clusters of saplings of OO, called Hedge Apple trees around here. And these dang things have nasty thorns! I spend months walking down there and clipping them off as low as I could to the ground. Then I dragged 'em to a nice spot in my forested area and piled the branches up. I consider them my prime nuisance, but if they didn't have thorns then perhaps they could be grown and marketed.
Not to hijack the thread, but I read up on Osage Orange trees. They were a natural tree in America, but only grew in the Red River area where Texas, Louisiana and Arkansas come together. No farm animals will eat the fruit, and birds don't like it, although horses may taste them a bit after they fall to the ground according to my neighbor. Some scientists surmise that with the heavy fruit evolution would not have favored the tree unless something ate it and pooped the seeds out in different locations. Some think that might have been the giant ground sloth, which went extinct about 12,000 years ago. It was used as a hedge to contain livestock before barbed wire. During the depression the federal government created a dual purpose work program to plant the Osage Orange all over the midwest. Created jobs and the idea was to create wind barriers to cut down on soil loss during those dust bowl years.
Another name for the OO tree is "Ironwood Tree". Really hard wood - will dull chain saws fairly quickly. Native Americans used the wood to make bows - and early French settlers also used the wood for that purpose. It is a very pretty cream color with the bark stripped off, with a green/yellowish tinge, and the mature trees around my property don't seem to have quite the thorns the younger saplings display.
If you know more about marketing these, and about the thornless variety, please share. The dang things grow GREAT on my property!
