Growing Black Walnut for Nut Production
Eastern black walnut trees (Juglans nigra) produce high-value, hardwood products and distinctively flavored, edible nuts. The potential for producing two valuable products from the same tree has captured the imagination of tree planters for years. While black walnut trees can be grown for timber and/or nut production, the focus of this guide is toward planting, managing and harvesting top-quality black walnut nuts for sales at the retail or wholesale level from an orchard practice, similar to pecan and other nut trees. This guide is a collaborative effort of the nut tree research cluster at the Center for Agroforestry and the nut research program of Kansas State University and represents a decade of research on growing black walnut trees in an orchard practice for nut production.
