| Special Attributes and Considerations |
The Black Walnut tree has a special defence mechanism know as Allelopathy. The tree's roots exude a natural herbicide known as juglone. The toxicity of juglones to other plants is still up for debate, but potatoes, tomatoes, apples and lilacs may be stunted if grown within close proximately to a Black Walnut tree. Rest assured, turf grass and Black Walnut trees get along just fine. |
