Whip Grafting. Secure a scion of the same size as the stock. 



Trim the scion at the lower end into the shape of a double wedge 



as shown under (a) in the dia- 

 gram. Then slip the scion into 

 a double wedge-shaped cleft (6) 

 as shown under (c), and finally 

 wrap it as shown under (d). 



The grafting cloth may be 

 made by coating thin muslin 

 with ordinary grafting wax. 



Grafting by the two methods 

 just described is known as Stem 

 Grafting. 



Root Grafting. In this 

 method the roots of seedlings 

 one or two years old are used 

 as stocks, and either the whole 

 primary root or only a piece of 

 the root may be used. The 

 method of procedure is similar 

 to that prescribed for ordinary 

 whip grafting already described. 

 Propagating Plants by Layering. This is one of the safest and 



simplest ways of propagating plants. The branches while still 



attached to the 



parent plant are 



covered with soil 



with the exception 



of the tips of the 



branches. In a 



short time roots are 



developed from the

covered portions of 

 the stem and a new

black raspberry and the strawberry are 



examples of plants that propagate by layering in nature. The 

 currant and the grape are examples of plants that may be made 

 to propagate by artificial layering.
