PRACTICAL PLANT PROPAGATION 



PRUNUS Continued 



If the Plum is not a strong grower, however, there is danger of the 



roots being inadequate for the 

 best development of the Al- 

 mond. P. Amygdalus var. nana 

 is best budded at a height of 

 three feet upon Plum. (See 

 also Plums, p. 140, and Peaches, 

 P . 137). 



ROOT CUTTINGS. P. A. nana is 

 successfully propagated by cut- 

 tings of large roots made in 

 Autumn stored in damp moss 

 until Spring. 



Prunus. C eras us. Ornamental 

 Cherries. 



RUDDING. Use the Mazzard stock, 

 usually, especially for budding 

 P. Cerasas Sieboldii rosea plena 

 (Jap. Weeping Cherry) and 

 sir ens is plena (Chinese Double 

 Flowering Cherry). For weep- 

 ing sorts, two buds; for others 

 one is sufficient to make a head. 

 Careful attention to heading 

 back the growth of bud will 

 help to make greater symme- 

 try. Spring grafting is not so 

 successful. (Refer also to 

 Cherries, p. 136.) P. Mahaleb 

 is good for dwarfing the orna- 

 mentals. 

 PSEUDOLARIX. Golden Larch. 



SEEDS. Obtainable from Japan. 



GRAFTING. Graft on Larch out- 

 doors, or better still, in the 

 greenhouse. For indoor graft- 

 ing pot plants in Spring so that 

 they are established by Au- 

 tumn and can be stored until 

 late Winter, then brought into 

 heat to start growth. When the 

 buds swell, it is time to graft. 

 Cut cions in Winter and hold 

 dormant in cool conditions. 

 PSEUDOTSUGA. Douglas Spruce. 

 *SEEDS. Generally so propagated. 



Fig. 102. Double flowering Almond. 

 The cut shows a characteristic branch 

 of Prunus triloba var. plena. This variety 

 when grown as a standard and worked 

 upon the Plum is often short-lived. It is 

 best propagated byjlayering or root graft- 

 ing. It makes an excellent subject for 

 forcing, but is also used for gardens (See 

 page 207) 



Sown in Spring. Eastern grow- 

 ers should demand Eastern or 

 Colorado seed, as the California 

 seed is tender. 



GRAFTING. The weeping form is 

 grafted on the common stock. 



INARCHING. Used on weeping form.
