66 Pecan-Growing 



The advantage of the bark-graft method is that when suc- 

 cessful the growth starts early in the spring, resulting in 

 the development of very strong \dgorous shoots the first season. 

 The disadvantages are that it is expensive of budwood and 

 makes a very severe wound that is slow in healing. 



Robert P. Morris^ describes a method of modified bark- 

 grafting which he terms bark-slot grafting. Some of the 

 outstanding features are that the work can be performed 

 during a part of the growing season, that very large limbs 

 or trunks can be grafted, and that the entire cion, buds and 

 all, as well as all cut surfaces, are coated with melted paraffin. 



Further modifications of and improvements on bark-grafting 

 methods have been devised by 0. J. AVenzel, of Putney, 

 Georgia, who has employed them very successfully in top- 

 working pecan trees. He nailed the cions in place rather 

 than using the '^Spanish windlass," a method of tying the 

 cions in place devised by Morris. The three improvements, 

 with directions for application as given by Wenzel, are : nail- 

 ing, making the top side of the cion shorter, and straight side 

 cuts on the cion just through the bark. Cions of various sizes 

 are nailed with appropriate sized nails. The nails should be 

 placed high so as to give strength and to locate them at the 

 maximum distance from the point where union first takes 

 place and is most active, i.e., near the point of the wedge. 

 Those most suitable are cigar-box nails. Wire brads of the 

 same size may be used, but are not so desirable as there is a 

 tendency for the cions to fall off over the heads of the brads 

 in high winds. 



In using this method it is well to observe the following 

 order and precautions: Cut the cion roughly to shape with
