For what it's worth: I, too, planted a row of tomatoes essentially 
under a black walnut, as stupid as it sounds. The tree was a 
beautiful black walnut and it was east of the main garden. In the 
first two east rows, I planted tomatoes. Didn't even realize what I 
did until a visitor said 'Funny, I didn't know tomatoes could grow 
this close to a black walnut."

The following year, I planted winter squash in those rows. The vines 
did great and in September we harvested a bumper crop of GROUND 
HOGS!!! (one actually had a burrow right below the trunk of the tree.)
