Shag-bark hickory (member of the Walnut family) - will it cause allopathic 
toxicity due to the amount of juglone released by its roots to fruit-crop 
trees like Prunus (cherry, apricot, etc.) and other plants like che 
(Cudrania)?


I know that shag-bark hickory produces far less juglone then black walnut.  
Thanks,
Steve
