If you have Black Walnut trees consider using Arborvitae. The roots of Black Walnut (Juglans nigra L.) and Butternut (Juglans cinerea L.)are known to produce a substance known as juglone (5-hydroxy-alphanapthaquinone). There are many plants such as blackberry, blueberry, azalea, mountain laurel, rhododendron, white pine and apple may be injured or killed within one to two months of growth within the root zone of trees. The toxic zone from a mature tree occurs on average in a 60 foot radius from the trunk, but can be as far as 80 feet. The area affected extends outward each year as a tree enlarges. Many susceptible plants will be dead within the root zone and fail at the margins.
