GRAFTING AND BUDDING 



GRAFTING and budding are the most artificial 

 methods of propagation, but very useful. These 

 operations result in the improvement and the 

 perpetuation of many of our ornamental and 

 valuable varieties of trees and shrubs. 



Grafting is the process of inserting a scion 

 of two or more buds into a stock. 



Budding is the process of inserting a single 

 bud into the stock. 



A scion is a portion of a plant which is me-

The stock is a plant or part of a plant on 

 which a scion or bud is set. 



It is necessary to select for a stock a good, 

 strong, healthy plant, well rooted and capable of 

 providing food for the scion. 



Grafting is practicable nearly all the year, 

 but in most cases is performed in the spring 

 during the season of greatest growth. To be 

 successful it is necessary for the cambium layer 

 of the scion and stock to meet as perfectly as 

 possible. During this season the cambium layer 

 lying between the wood and bark is simply a
