MORE ABOUT THE ROSE MIDGE 



The rose midge (Dasymura Rhodo- 

 phaga Coq.) may be present in the 

 greenhouse all the year, but there are 

 only one or two seasons when serious 

 damage is done, namely, in the spring 

 during the latter part of May to early 

 July, when about half the buds are 

 damaged and in the fall — early Sep- 

 tember to November 1, when the en- 

 tire crop of buds will be damaged. 



The adult is a small fly. The larvae 

 or maggots do the damage and the 

 venerable point in the life-history is 

 when they go into the ground to 

 pupate. If you will cover the soil of 

 your rose beds with tobacco dust it 

 will kill the larvae as they are going 

 into the ground to pupate. 



In addition to this you should fumi- 

 gate your rose houses every night for 

 a period of four weeks at least with 

 tobacco fumes in order to kill the 

 adults before they lay eggs. Per- 

 sistant work will soon eradicate the 

 insect from your houses. 



If the walks and under the benches 

 in your houses are earth, you should 

 spray them with a 10 per cent kero- 

 sene emulsion to kill the larvae that 

 enter the soil for pupating.

IRIS SIBERICA 



Iris Siberica or the Siberian Iris is 

 one of the most valuable of the Irises 

 for the garden. It blossoms in late 

 June and early July, giving flowers at 

 a time when very few flowers appear 

 in the hardy garden. It seems equally 

 adapted to both dry and moist places; 

 growing strong and healthy in a very 

 heavy soil, and doing equally well in 

 light sandy loam. The variety Siberica 

 which is a very deep blue or rich pur- 

 ple, which is illustrated, was photo- 

 graphed July 1st, at which time my 

 Siberian Irises were very good. The 

 best time to plant this species is in the 

 Fall, during August, September and 

 October, planting roots between two 

 and three inches deep. Cultivation is 

 the principal requirement, although 

 fertilization adds to the size of the 

 pl3nt, which in turn gives you larger 

 and better quality flowers. Any well 

 decayed dressing is good, and can be 

 applied anytime throughout their grow- 

 ing season. The best time to fertilize, 

 is when you are preparing your soil to 

 plant them, or early in the Spring, 

 when cultivation should be com- 

 menced.
