THE PROPAGATION OF ROSES 



plant, scientifically notching it with a knife (tech- 

 nically known as tongueing), and then putting the 

 tongued portion into prepared ground, after which 

 it is held in place by various methods. Roots are 

 formed at the break and eventually the part so 

 treated may be detached from the original plant, 

 and becomes itself a complete plant. 



Pemberton in "Roses Then* History, Develop- 

 ment and Cultivation," gives very clear and explicit 

 instructions on layering. 



SUCKERS 



Pemberton's description of suckers we quote as 

 follows : 



"Many of the species, such as RUGOSA, ALPINA, 

 SPINOSISSIMA and LUCIDA, together with Provence 

 and Damask hybrids, etc., increase by throwing out 

 suckers, springing up at some distance from the 

 parent plant, and forming roots at the place where 

 they bend upwards. These rooted suckers, after 

 being separated from the plant, should be pruned 

 back to a foot or even less, and then treated as 

 ordinary plants." 



CUTTINGS 



Cuttings are slips taken from plants which, when 

 placed in sand and soil, grow roots of their own and 

 become in turn rose plants, giving the same bloom
