EOSES IN WINTER

red spider, the chief means of control is syringing with 

 either clear or soapy water. If the plants are intelligently 

 ventilated and given, at all times, as much fresh air as pos- 

 sible, the red spider is less likely to appear. For mildew, 

 which is easily recognized by its white, powdery appear- 

 ance on the foliage, accompanied with more or less distor- 

 tion of the leaves, the remedy is sulfur 

 in some form or other. The flowers of 

 sulfur may be dusted thinly over the 

 foliage ; enough merely to slightly whiten 

 the foliage is sufficient. It may be dusted 

 on from the hand in a broadcast way, or 

 applied with a powder-bellows, which is 

 a better and less wasteful method. Again, 

 a paint composed of sulfur and linseed oil 

 may be applied to a portion of one of the 

 steam or hot- water heating pipes. The 

 fumes arising from this are not agreeable 

 to breathe, but fatal to mildew. Again, 

 a little sulfur may be sprinkled here and 

 there on the cooler parts of the green- 

 house flue. Under no circumstances, 

 however, ignite any sulfur in a greenhouse. 

 of burning sulfur is death to plants. 



Propagation. The writer has known women who could 

 root Roses with the greatest ease. They would simply 

 break off a branch of the Rose, insert it in the flower-bed, 

 cover it with a bell -jar, and in a few weeks they would have 

 a strong plant. Again they would resort to layering; in 

 which case a branch, notched half way through on the lower 

 side, was bent to the ground and pegged down so that 

 the notched portion was covered with a few inches of soil. 

 The layered spot was watered from time to time. After 

 three or four weeks roots were sent forth from the notch and 

 the branch or buds began to grow, when it was known that 

 the layer had formed roots.
