Is there any type of application to fight the toxic effect of the black walnut? I have planted some weeping willows in close proximity to several black walnut trees...did this before I knew the black walnut can be toxic to plants and trees. Would the weeping willow possibly be immune? Thanks

Yes, willow species are immune to Juglans, the chemical produced by black walnut. Looks like you should be ok. https://www.mortonarb.org/trees-plants/tree-and-plant-advice/horticulture-care/plants-tolerant-black...
