OUTDOOR ROSE GROWING 



Hybrid Tea and Hybrid Perpetual Climbers (other 

 than sports) and tender Hybrid Polyantha Climbers, 

 such as Cecile Brunner, should be treated on some- 

 what the same principle as the Wichuraiana Climbers. 

 The difference is that their wood winter kills more 

 easily, and therefore no thinning out of old canes 

 should be done before spring, and then only when such 

 canes crowd the new growths. The laterals on main 

 canes should be cut back to from two to four eyes. 



Climbing sports of dwarf roses, Tea Climbers and 

 Noisettes should be pruned more sparingly. Old 

 canes should only be removed as they become profit- 

 less, laterals but slightly shortened unless they are 

 crowded. In the case of all climbers better results 

 will be obtained if they are carefully and system- 

 atically trained and fastened in place. Most Hybrid 

 Tea Climbers, Noisettes, and all the Teas need winter 

 protection, as above described. 



For all climbers, on account of the greater evapo- 

 ration due to their larger growth, much more water 

 is necessary than for dwarfs. 



The peat moss mulch, noted later, is strongly 

 recommended. 



In the extreme North the summer thinning of the 

 wood of the hardy climbers is advocated by some 

 authorities so that the canes left will become thor- 

 oughly matured.
