CHAPTER XXIV. 



ON INSECTS THAT INFEST AZALEAS. RED SPIDER, MEALY BUG, 



ETC. ENGRAVING OF FLORAL ATOMIZER. 



There is no reason why red spider should be allowed to 

 destroy the fresh greenness of the leaves of the Azalea, if 

 the directions have been followed for syringing the 

 foliage. 



Insects are the cause of disease, therefore watch the 

 plants closely to keep them in a healthy condition, and 

 there will be no fear of a serious attack of any insect. 



I find it impossible, with all my care, to keep the Azalea 

 perfectly clear of red spider during the months of March 

 and April, or just before they are removed from the green- 

 house to the open air, during the named months. I do not 

 allow this pest to become so numerous that either the plants 

 or foliage are affected by it. 



To prevent an increase of red spider, syringe thoroughly 

 to create a moist atmosphere. 



Soon after being removed to the open air, red spider 

 will disappear. Keep up the usual amount of syringing 

 with clean water during the summer months, or until the 

 dews are heavy. 



Red spider cannot exist in a moist atmosphere, but will 

 increase very rapidly in a hot, dry, or in an untidy house. 



Mealy bug will seldom be found on the Azalea, unless 

 syringing has been neglected. 



On the old branches of plants ten years and older, 

 will be found a white scale, which in looks resembles the
