Grafting Wax
The necessity to protect graft unions by excluding air and moisture from cut plant tissue led to the use of balls of mud in ancient times. Later, various kinds of waxes were used.
In 1879, Prof. J. L. Budd[2], head of the Horticultural Department at Iowa State College, using resin and linseed oil, side grafted 150 varieties of Russian apples received from the interior of Russia in the winter of 1878. A boy swabbed hot wax on the grafts, using a lantern heater not too different from those used nowadays.
Mr. F. O. Harrington and Mr. S. W. Snyder, Iowa nurserymen were teaching grafting to members of the Iowa Horticultural Society in 1900, 1901 and 1902, at their annual meetings. Mr. J. B. McLaughlin[9], College Springs, Iowa, speaks of successfully grafting walnuts in 1900 in a discussion of the horticultural society led by Van Houton, Edwards, etc.
In 1909, Mr. E. A. Riehl[14] gave a talk before the Iowa State Horticultural Society in which he advocated covering the whole walnut scion, buds and all, with liquid wax. His first Thomas grafted tree is in a ravine back at his barn at Godfrey, Illinois. It was planted about 1902[12].
In 1910, the Northern Nut Growers' Association was organized by Prof.
John Craig of Cornell University, Dr. Robert T. Morris, Dr. W. C.
Deming, Mr. T. P. Littlepage and others. Craig had previously been at
Iowa State College where he and Budd had shown much interest in nut
trees.
In 1912, Mr. J. F. Jones [1][7], came up from the South where he had been successful in pecan grafting and started a black walnut nursery at Lancaster, Penna. He had been in Florida up to 1907. While in Florida he became acquainted with Mr. John G. Rush, of Willow Run, Penna., and did some walnut grafting for him. It was Mr. Rush who advised him to go to Lancaster and start a nursery for northern black walnuts. Jones patented his patch budder in 1912, and using the hot wax method developed by Mr. E. A. Riehl was very successful in walnut grafting.
In 1914, Dr. W. C. Deming and President T. P. Littlepage of the N.N.G.A.
and Messrs. C. A. Reed and C. P. Close of the USDA had a conference in
Washington which resulted in the publication of the American Nut
Journal.
Paraffin In Grafting
Dr. Robert T. Morris[10], writing in the American Nut Journal in 1929, advocates the use of paraffin to cover walnut grafts instead of wax. Both he and Dr. J. Russell Smith[15] credit Mr. J. Ford Wilkinson with first using paraffin instead of wax on walnut grafts. Mr. Wilkinson wrote that he got the idea from seeing a careless workman splash paraffin on the buds as well as on the union in fruit tree grafting at the McCoy Nursery about 1914. The author bought apple and plum grafts about 1922 from the Gurney Nursery which were all covered with paraffin. It was at conventions of the Northern Nut Growers' Association that new methods like this were passed along to members.
