A Member: Does that work on pecans as well as hickories?
Mr. Jones: Yes sir. To show the value of this patch, we have grafted rows side by side and got 80 per cent where we used this patch and 34 per cent where we waxed it over solid and left no ventilation or exit for the sap.
A Member: Isn't that to keep the wax out of the cambium layer?
Mr. Jones: Yes sir, it does that too.
Prof. Smith: Are there any fine points about this trimming, other than mere wedge?
Mr. Jones: No sir, only it's thick on one side, as you will see so that it wedges tightly.
A Member: Isn't it a fact that you can use three and four year pecan wood just as well?
Mr. Jones: Yes sir, two year wood or three will give you better results than one year.
Col. Sober: What time in the season do you graft?
Mr. Jones: The 20th of April to the 20th of May here.
