CLIMBERS 



only thinning, but were ignorant of the interesting 

 fact regarding the sub-laterals. It will be readily 

 understood how easily the above-named climbers 

 could be spoiled by unintelligent pruning. 



Hybrid Tea and Hybrid Perpetual Climbers (other 

 than sports) and Polyantha Climbers should be 

 treated on somewhat the same principle as the 

 Wichuraiana Climbers. The difference is that their 

 wood winter kills more easily, and therefore no thin- 

 ning out of old canes should be done before spring, 

 and then only when such canes crowd the new 

 growths. The laterals on the 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. 



We strongly recommend for them the peat moss 

 mulch, noted later.
