50 CULTURE OP THE ROSE. 



begin to swell, and lose no opportunity to give air on mild 

 and bright days. Raise the heat gradually till it reaches 

 sixty degrees ; which is enough during the winter months, 

 so far as fire-heat is concerned. The heat of the sun will 

 sometimes raise it to seventy or eighty degrees. Syringe 

 every morning ; and, if the aphis appears, fumigate with 

 tobacco ; then syringe forcibly to wash off the dead insects. 

 As the plants advance in growth, they require plenty of 

 water ; and, as the buds begin to swell, manure- water may 

 be applied once or twice. When the buds are ready to 

 open, the pots may be removed to the greenhouse or 

 drawing-room, and another supply put in their place for a 

 second crop of flowers. When the blooms are faded, the 

 flower-stalks may be cut back to two or three eyes, and 

 the plants placed again in the forcing-pit for another crop. 

 This, of course, is applicable to ever-blooming roses only. 



The most common and simple way, however, of obtain- 

 ing roses in winter, is to grow them on rafters in the green- 

 house. Some of the Noisette, China, and Tea roses, thus 

 treated, will furnish an abundant supply of excellent 

 flowers. By pruning them at different periods during the 

 summer and autumn, they will be induced to flower in 

 succession ; since, with all roses, the time of blooming is, 

 to a great degree, dependent on the time of pruning.
