ii8 ROSES FOR ENGLISH GARDENS 



if attacked directly they make their appearance and 

 never afterwards allowed to congregate in any great 

 numbers. Occasional sharp s5Tingeing with a garden- 

 engine with clean water will be found in most cases 

 sufi&cient. Should this, however, prove ineffectual, 

 the following well-known remedy may be used in- 

 stead. Take two ounces of quassia chips and boil 

 them in a gallon of water, adding a tablespoonful 

 of soft soap before the mixture becomes cold. Or 

 one of the man}^ insecticides in the market may be 

 tried, keeping strictly to the directions supplied with 

 the bottle. 



Thrips. — These tiny creatures often injure Rose 

 blooms in hot and dry weather, especially those of 

 the Teas, by giving the petals a brown and bruised 

 appearance. Spraying or syringeing with clean water 

 is the best remedy to employ, even at the risk of 

 spoiling some of the existing blooms. 



Red Spider. — This is another dry-weather enemy, 

 and so small as not to be detected with the unaided 

 eye. It generally attacks the lower sides of the leaves, 

 and if not kept in check causes them to fall from the 

 plant prematurely. The same remedy as for thrips is 

 advisable. Crimson Rambler, when grown in hot or 

 confined positions, is rather subject to this pest. In 

 dealing with large plants like this, it will be found a 

 good plan to use a small watering-pot with a fine rose, 

 and each evening in dry weather to wet both sides of 

 the leaves by swinging it sharply up and down and 

 across the climber.
