wall, protected in winter by a single thickness of burlap, does the best. The 

 Harrison and Persian Yellow do fairly well without protection. The following 

 thrive unprotected: R. riigosa, R. mollis, var. poniifera, R. spinosissima, 

 var. Altaica (a lovely single white, resembling the Cherokee rose), R. nitida, 

 var. alba, R. riihrifolia (R. ferruginea), and the sweetbriers. 



The following are well adapted to wild gardening, and are native to this 

 section: R. setigera, R. Engelmanni, R. blanda, R. Carolina, and R. humilis. 



Pruning Roses 



By B. M. Watson 



In Bailey's "Cyclopedia of American Horticulture" some fifty species 

 of roses are enumerated as common in cultivation. From these species 

 innumerable varieties have sprung. It seems impossible, in a genus so 

 diversified, to give any general rules for pruning, but by classifying roses by 

 their habits of growth it is hoped that some help 

 may be gi\'en the inexperienced grower. It is 

 assumed in what follows that the plants are well 

 cultivated and have plenty of nourishment. 



I. Hybrid perpetuals, hybrid teas, Provence 

 and moss roses are best grown as bushy plants. 

 They should be severely cut back while dormant 

 in spring, but never in summer or early autumn, as 

 is sometimes done because they are straggling and 

 look unkempt in an otherwise neat garden. From 

 two-thirds to four-fifths of last year's wood, and all 

 weak shoots, are removed. This results in strong 

 growths, producing large fiow^ers, the size of which 

 can be increased by disbudding. If numerous 

 smaller flowers are desired — i. e., quantity at the 

 expense of quality — the shortening-in need not be 

 carried so far. It is permissible to cut back only 

 one-half, but this treatment is objectionable, 



and does not tend to keep the plants in good condition. This winter 

 pruning should be supplemented by a summer pruning, which consists 

 of simply cutting out the flowering shoots after the flowers fade.
