Eastern black walnut trees (Juglans nigra) produce high-value, hardwood products and distinctively flavored, edible nuts. The potential for producting two valuable products from the same tree has captured the imagination of tree planters for years. Both large and small black walnut plantations have been established with the intent to harvest huge nut crops from trees that will eventually produce veneer-qualtiy logs. However, if experience has taught us anything about black walnut, it is that optimum nut production and optimum wood production are not normally produced by the same tree.
