In Reply to: Planting under Walnut Trees posted by Nicky on April 25, 19100 at 00:49:27:
: I have a grove of large Black Walnut trees and have been told that their roots are toxic to certain plants. My Doublefile Viburnums are thriving beneath them, as are mass plantings of daffodils. I would like to plant a Kousa Dogwood within close proximity. Can you tell me if it will be compatible? Thank you.
