WhijJ- grafting is the method of gTafting performed on small stock, 

 as in the nursery. It is best done with stock and scion not more than 



one-half inch in diameter. . The 

 upper end of the stock is cut 

 obliquely, so that the cut will be 

 from three-fourths to one inch 

 long. A cut is then made into the 

 upper end of the stock, so as to 

 form a "tongue" (Fig. 19 [2]). 

 The lower end of the scion is cut 

 in a similar fashion (Fig. 19 [1]). 

 The tongue of the scion is then 

 pushed into the cleft of the stock, 

 so that the cambium layer of both 

 Avill be in contact (Fig. 19 [3]). 

 The union is wrapped firmly with 

 grafting cord. 



In explaining whip-gTafting it 

 is often recommended that in preparing the stock and the scion that 

 they be "split." This is not necessary; it is sufficient if a small 

 incision or cut is made into stock and scion. 

 This will bring enough cambium together 

 and will hold the scion in place. It will 

 also obviate the unnecessary deep cleft or 

 split, which may be of injury to the union. 

 The scion should be at least four inches long 

 and contain not less than two buds. 



Whip-gTafting is much practiced in root- 

 grafting. In this method a whole root or 

 piece of root is used for stock. In case only 

 a piece is used it should be not less than 

 four inches long. It is simply to give the 

 Rcion a temporary root system. The scion 

 will soon strike roots of its own, which is 

 the object sought. It is of great importance 

 wher(» a stock of known merits is desired. 

 For example, a very hardy variety, or one 

 resistant to diseases and insects, could be 

 established on its own roots. 



Ivoot-grafting should be performed in 

 winter and the grafts tied in bundles of fifty 



and stored in moist sand or sawdust in a ^'''- persTnTmoi^"'"''™*' °'' 

 cool cellar until ])I;iiiting time. 



Cleft-grafting. — This is one of the sim- 

 plest methods of grafting. It is almost always used in top-grafting-
