Jujube propagates by seeds, layering, division and cuttings. 



Myricas are grown from seeds, root cuttings, layering, 

 division and grafting. The same species are used as stocks. 



Chestnuts propagate by seeds, inarching, side-grafting, 

 cutting-grafting and other means. Wild chestnuts and 

 common seedlings are used as stocks. Graft in March. Scions 

 have to be cut and stored for about three to five weeks before 

 grafting. 



Japanese walnuts are propagated by seeds. In the case 

 of grafting, walnuts are used as stocks. Ginkgos are propagat- 

 ed by seeds. Grafting is seldom used. They are grafted on 

 Ginkgo by Kiritsugi and splice grafting. 



Torreya are grafted by inarching on its wild species. 

 Seeds are often used to grow them. 



White Pines CPinus Koraiensis) are grafted by inarching 

 or cleft grafting upon wild-grown black pine (P. Thumbergii). 



Vines have long been propagated by layering in its 

 growing centers of Kai. Cuttings, division and grafting are 

 also familiar methods. Eye-cuttings have lately been intro- 

 duced from Europe. They are grafted on other grape cuttings 

 or on the wild grape (vilis •Coig'netiae). Cuttings are best 

 done from November to May. But late February to March 

 is best to make them root. Graftings are best performed in 

 March. 



Mulberries are grown by division, layering, cuttings and 

 grafting. They are very easy to strike: Divide in May, 

 when shoots have grown i foot or more. Cutting is done 

 in February. Graft at the same time. 



Goumi are easy to divide while cuttings are also easy. 

 Work in spring before sprouting. 



Japanese gooseberries will propagate by suckering, Cut- 

 tings, layering and division. Insert cuttings in bads in February. 

 Mound in May around the shoots, and then divide. 



Brambles readily propagate by suckering and cuttings 

 Begin the work before sprouting.
