THE RED RASPBERRIES 



Propagation 



Red raspberries propagate by means of 

 suckers. Root-like underground stems bearing 

 fibrous roots radiate from the crown of the 

 parent plant. These creeping underground 

 stems are nearly horizontal and from them 

 suckers appear during the growing season at 

 some distance from the crown. These suckers 

 are readily transplanted. Suckers are pro- 

 duced by common varieties in such abundance 

 that propagation is not a problem at all. They 

 are the worst weeds in the plantation and large 

 numbers must be removed each year to keep 

 the rows within bounds and to prevent crowd- 

 ing of plants in the rows. 



Occasionally it becomes desirable to in- 

 crease the production of new plants, as with 

 a new variety or a valuable supply of disease- 

 free stock. The growth of suckers may be 

 stimulated by cutting the underground stems 

 or otherwise disturbing them. They are not
