I have black walnuts all around my feilds , as long as Im more than 10 feet from the outside edge of the canopy I have no problem with growing any vegetables except for greens, including lettuce, they seem especialy sensitive. Also blueberries dont seem able to tolerate it either.

the Permaculture literature has addressed this issue very well. I would suggest looking towards the index of David Jacke's book "Edible Food Forests" printed by Chelsea Green. There is a composite of plants resistant to juglone. I know one can use mulberries and elderberies in a guild with Juglans nigra (Black Walnut). These plants effectively buffer and partly neutralize the allopathic effects of juglone in the surrounding soil profile.

Most vegetables can be affected. The high-risk zone is anything within 1.5x the drip line. Some think its more because it depends on sensitivity/tolerance and movement of walnut debris. > > Bill > > William H.
