Bush-Fruits 



made from wood of the previous season's growth, cut 

 four or five inches long. They may be taken in the fall 

 and stored, or cut when wanted. They may be started in 

 the greenhouse and transferred to the coldframe later, or 



put in the coldframe at 

 first. The important 

 point is to avoid high 

 temperatures. 



For the cutting-bed a 

 one-inch layer of clean 

 sphagnum is placed on 

 a good drainage founda- 

 tion. This is covered 

 with three inches of clean 

 sand. The base of the 

 cutting should reach 

 nearly to the sphagnum. 

 The frame must be 

 shaded and the sash 



Fig. 54. "Tubered" cutting with shoot tightly closed to secure a 



saturated atmosphere. 



When the first twig-growth has been completed, the 

 bed is mulched with about half an inch of sifted peat 

 two parts, and sand one part. When the cuttings 

 have begun to root, which is indicated by secondary 

 twig-growth, ventilation is begun. This must be very 

 slight at first, and increased slowly, through a period of 

 several weeks, before full exposure is given. Young plants 

 are very susceptible to injury from over-ventilation during 

 the propagating period. These winter cuttings are best 

 left in the coldframe over winter, being mulched with
