The solution above-named will banish green-fly, and also cripple red spider. But 

 to kill that pest and thrips it may be used a little stronger. For scale, reduce the 

 original mixture to four times its bulk, and apply with a brush. 



Mildew may be prevented, checked, and possibly killed with the weaker solution if 

 a little more sulphur be applied. This is by far the most effectual and cleanly way of 

 applying sulphur. In any other form of application we do not cover the whole of a 

 plant so evenly, and the unsightly appearance of uneven coatings is almost as bad 

 as the disease itself. For mildew outside, the weaker [solution is used with more 

 sulphur still. 



Caustic Soda and Potash for "Winter Use. — For dressing roses when they are 

 leafless in winter, for cleansing them from moss or other incrustations, also destroying 

 scale, as well as the eggs of aphis, red spider, or other pests, dissolve \ lb. each of 

 caustic soda and commercial potash (pearlash) in 5 gallons of water, and apply in 

 the form of spray, or through a very fine syringe. If this were done systematically 

 and effectively, no parts of the stems being missed, there would be fewer insects to- 

 combat in summer, as the eggs producing the first broods would be destroyed.
