PRUNING THE CHERRIES 



Since the growth and fruiting habits of the sweet and the sour cherry differ, 

 they require different pruning treatments, and it seems better to discuss them 

 separately. 



Figure 35. This Montmorency cherry tree had not been pruned for three or four years previous to 

 the treatment it has just received. The pruning consisted of the removal of many dead and weakened 

 twigs throughout the lower part of the tree and a thinning out of the top and outer parts. The prunings 

 under the tree show that many branches less than one-fourth inch in diameter and few larger than that 

 were removed. 



Siveet Cherry — The young sweet cherry tree may be trained in much the 

 same manner as the apple, except that growth habits make it advisable to do 

 less cutting back and more thinning (See figure 12). Perhaps a brief state- 

 ment regarding growth characteristics will explain the necessity for these 

 slight differences in treatment. 



The fruit is borne principally on laterals or spurs whose terminal bud is a 

 leaf bud. Growth of the spur is continued each year from its terminal leaf
