 apple trees should largely suffice. 



Japanese Plums — The Japanese plums should be trained as open center 

 trees and handled in a manner similar to that of training and pruning peach 

 trees, except that less cutting back is advisable. Since they bear much of

 of the tendency for the portion of the tree on the right side to outgrow that on the left, the former was 

 cut hack heavily and the latter very lightly; in fact, it was left longer than the right portion of the tree 

 because of the much smaller size of the branches.

 back of the previous season's growth, but less than that usually given the 

 peach, is desirable. However, it must be remembered that considerable 

 fruit is also borne on spurs similar to those of the properly functioning cherry, 

 which means that while the pruning, in general, is similar to that for the peach, 

 yet there should be an approach toward that for the sour cherry.
