PROPAGATION 21 



August, at which time they would be ready for 

 budding. Peach stocks can never be transplanted 

 without injuring them so seriously as to make them 

 almost worthless for further use. 



Peaches are also sometimes propagated on apri- 

 cot seedlings, and may be budded on almost any 

 species or variety of plum seedling. Dwarf peaches 

 may be produced readily by tliis method of work- 

 ing on any convenient species of plum. The one 

 commonly used is the French plum, Pr units ceras- 

 ifcra; a better dwarfing stock, however, will be 

 found in the native American plum, Primus amcri- 

 cana, or the sand cherry, Primus besseyi. 



Plums may be budded on almost any kind of 

 seedling plums. The one commonly used in the 

 nursery is the French plum, Pruniis ccrasifcra. In 

 the western states, Primus americana is more com- 

 monly used and has some advantages. For one 

 thing, it is hardier. It also has a decided dwarfing 

 effect, which is often an advantage. The sand 

 cherry, Primus besseyi, makes an excellent dwarfing 

 stock for most plums. 



Plums are often worked on peach seedlings. 

 Peach roots are particularly adapted to Japanese 

 plums, more especially when the orchard is to be 

 planted on warm, sandy soil. 



Cherries are nearly always budded upon cherry 

 stocks, and these stocks are extensively imported 

 from Europe, especially from France. In some 

 cases the seeds are imported and the stocks grown 

 in this country. These stocks are of two sorts, the 

 Mazzard and the Mahaleb. As a rule, the Mazzard 

 stock is recommended as the better one, especially 

 for the propagation of sweet cherries. The Maha- 

 leb stock is said to be hardier and easier to work,
