BARK GRAFTING 



Bark grafting is employed on limbs that are too large for cleft- 

 grafting. Limbs over two inches in diameter are best grafted 

 in this way. Bark grafting is often employed to replace large 

 limbs which have been destroyed. 



The essential principle in this form of grafting is the same 

 as that involved in cleft grafting. From three to twelve scions 



are placed in each stub, 

 according to its size.

 and cleft grafting 



The scions are cut very thin, with a shoulder on each side 

 (Fig. 33). The cut should be at least one inch in length and not 

 much more than one sixteenth of an inch in width. Why should 

 this cut be so thin ? Make a natural-size drawing of the scion, 

 showing the shoulder. The scion should contain three or four 

 well-developed buds. 



1. Make a drawing, at least four inches in length and two and 

 one-half inches in diameter, showing the stub and the location of 

 each scion. In this method the scions are placed between the bark 

 and the wood, and no cleft is made in the stub. A small penknife
