root systems, as shown in Figure 4. By the use of root cuttings the 
supply of stocks can be increased where seeds are not available. 
This method might also be employed to increase the supply of 
large-fruited varieties after they have once been rooted by layering 
or by the rooting of scions. 
BUDDING. 
Propagating the jujube b}- budding has not as yet given very 
satisfactory results. The wood is very hard and the bark thin, 
making budding a difficult matter. The results of budding in 
August or September have been almost entirely negative. Spring 
budding has -been more successful, but the percentage of trees se-

cuttings, made by clipping the lower ends of the roots from the stock plants, have 
given a good percentage of plants for stock purposes. 
cured by this method has been small. For spring budding the bud- 
wood should be cut in the dormant season (January or February) 
and held in a cold place, preferably in cold storage at a temperature 
above freezing, until the stocks begin to push and are full of sap. 
The common shield bud is the one generally used. In cutting the bud 
care must be exercised to avoid breaking it. The growth of the 
jujube branch is more or less angular, and the bud is so located that 
it is easily broken when an attempt is made to remove it. If the bud 
is cut from both above and below there is less danger of breaking. 
Twig budding has in some instances been reported as successful. 
GRAFTING. 
The most successful method of propagating the jujube has been 
by the ordinary whipgraft. Good results have been obtained both
