OUTDOOR ROSE GROWING 



are covered with little, light green insects Green 

 Flies or Aphides, which are common pests in rose 

 gardens. There is a very effective remedy for them 

 which will greatly check their future development; 

 this is to spray with a solution of tobacco stems and 

 whale oil soap. The best proportions are as follows: 

 Two ounces of tobacco stems to a bucket of water, 

 to which add an ounce of whale oil soap, first dis- 

 solved in a small quantity of hot water. It will take 

 about three hours for this to dissolve. It should 

 then be added to the tobacco mixture. Doctor H. 

 A. Surface, the Zoologist of the State of Pennsylvania, 

 recommends a mixture of one ounce of Blackleaf No. 

 40 with five gallons of water. This is more conven- 

 ient than the infusion with tobacco stems and gives 

 the same result. It may be bought at seed stores. 

 Add ly^ oz. of soft soap to the above so that the 

 spray will adhere to the foliage. The Aphides are 

 quickly destroyed with this spray and a gallon of 

 the mixture by careful application is enough for from 

 fifteen to twenty-five rose plants; by applying with 

 an ordinary whisk broom it will take care of fifty 

 plants and can be done as well, but it requires more 

 time in applying than with the sprayer. Spray three 

 days in succession. 



By this tune the ground will naturally need weed- 

 ing. It seems hardly necessary to go into details
