216 DISEASES. 



This species of fungus is not very common ; the 

 cure is to wash the stems and shoots with Gilhurst 

 compound ; if in winter and early spring, 6 oz. to 

 the gallon of soft water : if in summer, 3oz. to the

 spread on the wound with a spatula. 



There is yet another red or rather orange -

 thousands of young and old plants of these two old 

 favourite sorts with the under surface of every leaf 

 covered with a thick coat of impalpable bright 

 orange-coloured dust. No cure has yet been found 

 for this disease ; all the fungus remedies have failed. 

 There is a prevention the roses should be lifted

 be attended to, so as to give the roses a bed in 

 the rose garden which has had a crop of annuals 

 the preceding summer. 



In moist soils the stems and branches of 

 rose trees are often disfigured by the growth of 

 moss. They should be dressed in winter with
