Tree headed too high. 



force out shoots in the spring 

 and after they have made a suf- 

 ficient growth to determine 

 which one of the three is the best, 

 the other two are removed. The 

 one remaining shoot is then tied 

 securely to a stake, so that it will 

 not be broken or injured in any 

 way. In the second spring this 

 tree is re-headed to a height of 

 about forty-eight inches and the 

 heading formed so as to have the 

 main branches spaced as widely 

 apart as possible. This system 

 is a fairly easy one for the aver- 

 age man to handle. 



The second method is to head 



the trees much the same as our apple trees ; say, twenty-five to 



thirty inches in height and the main head is formed the first 



summer. With this system, how- 

 ever, extremely good staking and 



tying must be followed, or the 



head will not be satisfactory. 



This system is a superior one 



for the expert horticulturist. 

 The third system is to train 



the trees to whip for three or 



four years, allowing no laterals 



to grow until that time. This 



was formerly the most popular 



system in the Northwest, but is 



gradually going out as it makes 



the trees too high-headed, and 



makes it very difficult to stake 



and tie the main scaffold 



branches satisfactorily. English
