Black Walnut Allelopathy versus Young Maple

chickencoupe

Question about allelopathic nature of Black Wanut Trees: Will its allelopathic nature inhibit or bother the growth of a young maple about 3 years old? We lost a couple of walnut trees gracefully providing shade in the children's play area. Since then, we have permitted new growth at the stump. Now, we've discovered the maple nearby which is more worthy of growth in this area because of its low maintenance and native longevity. Should I kill the Walnut stump or will they be okay together?

The base of each tree spans approximately 2-1/2 to 3 yards from each other.
