JAPANESE DWARFED TREES. 



From the earliest times both Japanese and 

 Chinese gardeners have excelled in the curious art 

 of dwarfing trees, so that in their miniature land- 

 scapes they might have exact replicas in all but, 

 stature of their native forest trees. The whole art 

 of dwarfing trees lies in checking the sap flow and 

 removing all strong growths. The former is secured 

 by reducing the number of roots at an early stage 

 of the tree's life, by keeping the roots in narrow 

 and shallow pots (usually of artistic design), and 

 by preventing the roots 'from wandering over or 

 through the pots in search of food. Water is 

 sparingly afforded, and additional root room seldom 

 provided. Besides the simple process of dwarfing, 

 there is that of training, which is usually conducted 

 in such a manner as to materially check growth. 

 Sometimes only the tips of the roots are kept in the 

 soil and the plant appears to be standing on stilts, 

 and in addition to this its head may be trained 

 round and among the leading root branches, and

 which it grows. For the various styles of training 

 dwarfed trees the Japanese gardeners have dis- 

 tinctive names, and this is necessary when it is 

 remembered that more than one generation of gar- 

 deners may manipulate some of the trees ere the 

 full development of some particular style is reached. 



The trees selected for dwarfing are chiefly Cu- 

 pressus obtusa nana, the Chabu Hiba of the 

 Japanese ; Larix leptolepis, the Japanese Larch ; 

 Pinus densiflora, Nandina domestica, Porlocarpus 

 macrophyllus, Plums, Cherries, Japanese Maples, 

 and, in a lesser degree, Cycas revoluta and some 

 Bamboos. 



During recent years large importations of 

 Japanese dwarfed trees have been made into this

country by private individuals, by British nursery- 

 men, and also by enterprising Japanese growers. 

 The plants have found a ready sale among lovers 

 of the curious and interesting, but the cult is not 

 likely to become generally popular. At present 

 there is one nursery in England, near London, 

 devoted to Japanese dwarfed trees, and conducted 

 by an experienced Japanese.
