Iris 
Bearded Iris, continued 
and dust the remainder with lime or sulphur. The Iris Borer 
enters the upper leaves of the plant at flowering season. The 
puncture is easily seen and the young borer may be crushed. 
Later the borer works its way down to the root and may destroy it; 
therefore, it is well to be on guard early. Our nursery is on new ground 
and has been singularly free from these pests. 
We call attention to an article by J. Marion Shull on “Iris Root 
Rot,” in the February (1921) number of The Flower Grower. 
The following illustrations are used with the permission of the 
American Iris Society. They show the names and positions of the 
various parts of the flower and will assist in a clear understanding 
of the descriptions.
