Never heard of the juglone. I'll have to ask my favorite tree geek if there's any truth to "juglone" & stuff. I know he loves walnut trees (he's the town horticulturist) and is always trying to get people to get walnut trees. I think the only thing he's said bad about 'em is being knocked on the head by walnuts.
