246 THE PRINCIPLES OF FLORICULTURE 



heavily mulched with leaves. The larger part of the 

 hybrid perpetuals should be planted in the spring just as 

 soon as the frost is out of the ground. The teas are better 

 planted about May 1 after all danger of late frosts is 

 past. All varieties of the hybrid perpetuals should be 

 planted at least twenty inches apart. Fifteen inches 

 apart will be about right for the hybrid teas. 



As soon as the plants are received, they should be 

 examined carefully; and if the wood is shriveled, they 

 should be dipped in water or buried in a trench for about 

 three days. If frozen when received, they should not 

 be handled, but placed in a shady location where they 

 will thaw gradually. It is best to unpack in a place 

 sheltered from wind and sun. Before planting, all 

 broken roots should be cut off with a sharp knife. This 

 is very important, for bruised tissue never heals and if 

 allowed to remain, the root system easily becomes diseased. 



302. Depth for planting roses. Care should be taken 

 not to plant too shallow. This results in weak, spindling 

 growth, and many suckers are liable to spring from the 

 stock. On the other hand, they should not be planted too 

 deeply in the soil or the roots will be smothered. After 

 the soil has become permanently settled, the union of the 

 stock and cion should be about two inches below the 

 surface. The hole should be made large enough to ac- 

 commodate all the roots without crowding, and they 

 should be spread out carefully and horizontally. The soil 

 should then be. packed firmly about them and watered. 

 After watering, the surface soil should again be loosened 

 and covered with a light mulch of strawy manure. 



303. Cultivation. During the summer, the soil should 

 be stirred frequently and kept free from weeds. This 

 stirring should be lightly done, however, or the feeding
