164 THE PRINCIPLES OF PRUNING 



this variation is a matter of individuality. No 

 two trees are alike in this respect any more than 

 they are in form of top or length of life. 

 Some of the variation, however, is due to soil or

 plants have never acquired a bearing habit, the 

 grower may experiment, hoping to find something 

 which will bring them into fruit. One type of 

 experiment is to change the management of the 

 land ; another is to modify the plant -food ; an- 

 other is to change the method of pruning; another 

 is to give treatment for insects and diseases. 



The principle under discussion is the most im-

 out is better than a hundred experiments. 



Let us apply these reflections to the treatment 

 of a neglected and unfruitful apple orchard. 

 The general advice is to till, fertilize, prune and 

 spray ; and this advice is good. The pruning,
