black hills spruce and black walnuts

cdeckMay 17, 2006

I have read several lists of trees and shrubs that are tolerant to the juglone toxicity caused by black walnuts, however, I have not found anything about whether black hills spruce are resistant or sensitive to juglone. Can the two species co-exist?

I have seen that Norway Spruce are juglone tolerant but I would prefer the black hills variety.
