OUTDOOR ROSE GROWING 



ture with rain. Mildew is a disease of the leaves 

 which appears when there is too much moisture. 

 The use of peat moss will render watering to some 

 extent unnecessary. 



One other plague to watch for is the rose slug, 

 which chews the leaves. This pest must be destroyed 

 by a stronger preparation than tobacco leaves, as it 

 is very hardy and not as quickly disposed of as the 

 little green bug. The very best remedy is powdered 

 white hellebore. Make a solution of two tablespoon- 

 fuls hi a bucket of boiling water, and after it has 

 cooled apply it with a whisk broom under the leaves. 

 For the larger leaf eaters and borers it is necessary 

 to pick by hand. 



Watch carefully for any sprouts of the Manetti or 

 other stock, on which the roses themselves are budded 

 or grafted. The cutting off of these suckers from the 

 root itself is the proper remedy for this enemy to the 

 growth of the plant. 



Rose bugs or beetles are really the worst pests. 

 The only cure has been to pick by hand, dropping 

 them into- kerosene. 



Recently some growers claim success with the following kerosene 

 emulsion: 



K lb. (202) hard soap. 



1 qt. water. 



2 qts. kerosene oil. 



Dissolve soap in hot water and while hot add the oil Shake 5 

 to 10 minutes in jug until it becomes a creamy mass. 



Use 1 qt. emulsion to 6 qts. water. Spray roses from May 1st to 

 June 15th every week, also spray ground under rose bushes.
