Pruning Black Raspberries 



Because of their distinctive method of 

 growth, black caps are pruned quite differently 

 than red varieties. Black raspberries do not 

 send up suckers at a distance from the parent 

 plants and it is easier to keep the rows within 

 bounds. Propagation in clean land is inter- 

 fered with by the winds, which keep the tips 

 blowing around and tend to prevent their root- 

 ing, so it is not difficult to keep new plants in 

 check. 



Tipping in Summer — As with all raspber- 

 ries, the canes grow during their first season, 

 produce fruit the next, then die. Black rasp- 

 berry canes branch freely in their first year 

 when they arch over toward the ground. This 

 increases the bearing area of the canes, but 

 many of the branches produced naturally are 

 too far out on the cane to be kept off the 

 ground easily. 



To encourage earlier and stronger branch- 

 ing and to secure more stocky canes it is cus- 

 tomary for black raspberry growers to pinch 

 off the growing tips of the new canes when
