I have a medium sized black walnut in the yard and want to plant some blueberry bushes within about 10 feet of the base of the walnut. Are blueberries sensitive to walnut?
Many plants such as tomato, potato, blackberry, blueberry, azalea, mountain laurel, rhododendron, red pine and apple may be injured or killed within one to two months of growth within the root zone of these trees. The toxic zone from a mature tree occurs on average in a 50 to 60 foot radius from the trunk, but can be up to 80 feet.
