APPLE GROWING 



often differs from the habit of the same tree 

 in old age. The tendency is for a tree to con- 

 tinue Its growth from its uppermost or terminal 

 buds. Although the heading in of new growth 

 checks this upward tendency and throws the 

 energy of the tree Into the development of 

 lateral and dormant buds, nevertheless the 

 pruned tree soon resumes Its natural upward 

 growing habit. 



Plant food Is taken up by the minute tree 

 rootlets In solution and carried to the leaves 

 where it Is elaborated and then returned for 

 use to the growing tissues of the tree. When- 

 ever there is any obstruction above a bud the 

 tendency is to throw the energy of the branch 

 Into a lateral bud, but If the obstruction Is 

 below the bud the branch merely thickens and 

 growth Is checked. When too heavy pruning 

 Is practiced the balance between the roots and 

 top is disturbed. This usually results In what 

 are commonly known as " suckers." These are 

 caused by an abnormal condition and while they 

 may be the result of disease or injury to the 

 tree, they are often of great value in restoring 

 or readjusting the proper balance between the 

 roots and top. 



Pruning a tree Is a way of thinning the fruit
