218 THE BEGINNER'S GARDEN BOOK 



There are various enemies of roses. The rose bug must 

 be picked off, the aphis must be sprayed with soap or kero- 

 sene emulsion, the leaf -roller must be crushed. When the 

 bloom is over, mildew is likely to appear. Dust the tips of 

 the plants with flowers of sulphur, but best spray, before 

 the blight appears, with Bordeaux or the copper carbonate 

 solution. 



You see that the growing of roses, except the rugosa and 

 the climbers, is not easy. Many gardeners try it and give 

 it up. More credit to those who, with thought and work, 

 get fine flowers.
