i am trying to stop my massive walnut tree from producing. does anyone know
how to do this? i think it's a black walnut. it's pretty old, it shades
about 1/3 of an acre. thank you!

To stop a tree from producing, cut it down. If it *is* black walnut,
you may be able to sell the wood or trade it for the tree removal,
although *I* never had any success on that line.
