Many experienced nut tree propagators have little success in grafting the butternut. But Mr. Harry Burgart of Michigan, has found that nursery trees may be successfully grafted if the operation is performed at a point three or four feet from the ground, while the late Dr. G. A. Zimmerman of Pennsylvania, found that very early grafting gave him the best results. He reported that his best catch was from grafts set March tenth. Some moderately successful propagators do not pay careful attention to outside temperatures when they cut their scions. In contrast to this let us see what Mr. J. F. Jones thought about it. He was undoubtedly the most successful nut tree propagator in the East and he was always as generous in sharing his hard earned knowledge as he was skillful in its application in his own commercial nursery. Note this from his paper in the 1920 annual report. "In the case of trees that bleed freely when cut, we must guard against taking scions after hard freezing weather and before the tree has fully recuperated. This semi-sappy conditions following low temperatures that freeze the wood seems to be a provision of nature to restore the sap lost by evaporation. We always try to avoid taking scions of any kind soon after hard freezing weather. I have found scions of English and Japanese walnuts, cut from trees in this condition, to be practically worthless for propagation, although they may have been cut in late winter long before the sap gets up in the tree naturally." This warning would undoubtedly apply to the butternut as it bleeds freely when cut. Another pitfall for the inexperienced propagator lies in storing scions in packing material that is too moist. Sphagnum is commonly used. It should be no more than slightly moist to the touch.
