TEN PRINCIPLES OF PRUNING* 



BY JULIA E. ROGERS 



1. Pruning the roots lessens the food supply, and 

 so retards top growth. 



2. Pruning the top invigorates the branches that 

 remain, the root system being unchanged. 



3. Removing terminal buds induces forking, 

 thus thickening the branching system. It checks 

 wood production, and encourages the production 

 of fruit and flowers. 



4. Unpruned trees tend to wood production. 



5. Summer pruning reduces the struggle among 

 leaves and twigs for light and produces stronger buds 

 for spring. 



6. Winter pruning removes superfluous buds, 

 inducing greater health in those that are left to 

 develop. 



7. Dead wood should be taken out at any season 

 and burned. 



8. The best time to prune, generally speaking, 

 is just before the growth starts in the spring.
