It's well-understood that black walnut exceeds, respectively, English
(/Carpathian) walnut and hickory in its juglone toxicity to juglone-sensative
plants (i.e. bluberry, pears, etc.). However, "to a lesser extent" means
very little to me.

Will a juglone-sensitive plant be at all negatively impacted by the effects
of being planted near an English walnut - or, being yet lower in juglone
concentration, a hickory tree? My suspicion is: to an extent, yes w/English
walnut (J. regia), to much less an extent w/hickory (except maybe to a large
extent w/pecan hickory).

Any anecdotal evidences here?
