    Justis seeing you're the papaya guru, can you tell me if it's true that you can alter the sex of a papaya or paw paw tree by inserting a rusty nail into it's trunk?  I remember my grandmother used to tell me that when I was a kid, but like most grandmothers she was quite guilty of believing in things  which have since been shown to be myths.
