The whole object of the peach pruner is therefore to keep up 

 a supply of new wood. His short, interior twigs are often useless 

 after one year, in which case he may cut them out altogether. 

 In any case he prunes his tree much more severely than in the 

 apple, so as to develop new growth. Sometimes this new growth, 

 resulting from severe pruning, is so vigorous that it does not 

 bear much the first year but the operator knows that he can rely

 has to take out practically all the leaders, even though he knows 

 that they will be replaced by an equally strong growth.
