the black raspberries 



Propagation 



The black raspberry usually is propagated 

 by tip layering. As the new canes grow they 

 bend over and in late summer the ends reach 

 the ground. Some tips root well of their own 

 accord but when many strong plants are de- 

 sired it is best to open the ground with a spade 

 or hoe and insert the tips to a distance of two 

 or three inches to insure good roots. This 

 may be done at any time in late summer, but 

 it is best to wait until the ends of the canes 

 of spreading varieties like Plum Farmer have 

 reached the ground of their own accord, and 

 produced long slender tips. 



New plants are severed from the parent 

 plants in the following spring and are taken 

 up carefully on a spade to preserve as much 

 of the root system as possible. 



Experienced growers of black caps take 

 plants for transplanting from young and vigor- 

 ous parent plants, if at all possible. Black 

 varieties are very susceptible to diseases of 

 the mosaic type and plants from older bushes 

 are likely to carry some infection. Plants 

 from one- or two-year-old plantations are 

 more vigorous than those from plants that are 

 on the decline. Great care should be taken to 

 get new plants which are healthy and vigorous.
