5. Frequently a strong scaffold branch with a narrow crotch 

 angle develops in the upper third of the tree. If this 

 branch is not removed or its growth is not restricted, 

 the tree will become a multiple leader tree. Trees of 

 this type are much more difficult to prune when practicing 

 containment pruning or lowering tree height. 



6. Delicious trees are subject to weak crotches, and branches 

 are prone to develop in whorls and to droop. The ends of 

 drooping branches should be removed back to a lateral grow- 

 ing in a somewhat upright position. This will shorten 



and stiffen the branches. The tip of the lateral on a 

 pruned drooping branch should be higher from the ground 

 than any other portion of the branch. This should reduce 

 the problem, of suckering.

Increased Interest in Cherry Growing . Interest in cherry grow- 

 ing has increased in Massacnusetts because of labeling permitting 

 use of Mesurol* for repelling birds. While sour cherries are 

 relatively winter hardy, sweet cherries may be severely injured, 

 if not killed, by low temperatures. However, sweet cherries 

 can be grown successfully with limited amounts of nitrogenous 

 fertilizer. To eliminate or reduce injury to sweet cherry 

 trees caused by low temperatures, the soil under the trees should 

 not be cultivated. 



Sour cherry trees are smaller than sweet cherry trees and are 

 better suited for U-pick operations. At this time we cannot 

 recommend the use of dwarf rootstocks for either sweet or sour 

 cherry trees. 



Several sweet cherry varieties you may want to consider are 

 Emperor Francis, Schmidt, Hedelfingen and Windsor. Montmorency 

 is the most popular sour cherry variety; other varieties are 

 EArly Richmond, English Morello, North Star, and Meteor. North 

 Star and Meteor produce much smaller trees than the other varieties
