How Do You Grow Walnut Trees With Black Walnut Rootstock?
Black Walnut trees (Juglans nigra) are relatively easy to propagate by seed, or nut. However, the time it takes for the nut to become a tree can be prohibitive for many growers wanting quicker profit or gratification from their trees. If there are trees which growers want to replicate–hybrids that are particularly disease resistant or quick growing, for instance–using rootstock to clone a particularly well-performing tree may be a better way than gambling on a nut that may or may not have the genetic qualities of a favorite tree. With an extremely sharp knife, slice a slanted cut into the rootstock, across the center and close to the base where it will be planted in the ground. If the diameter of the rootstock and the scionwood are similar, you may cut diagonally into the rootstock deep enough to accept the width of the scionwood (wedge grafting). If the scionwood and rootstock are different sizes, you may have to cut into the side of the rootstock a width that matches the diameter o
