GRAFTAGE 



133 



In grafting Mammillaria, 

 Echinocactus, Echinocereus 

 and other globose or thick 

 sorts, a stock is selected which 

 is about the same diameter as 

 the cion. The top of the stock 

 is cut off perfectly level; the 

 cion is cut in the same way; 

 the cut surfaces are fitted 

 together and tied with a cloth 

 or soft cord. 



GRAFTING CONIFERS 



It is often highly desirable 

 to graft many of the conifers. 

 A. H. Hill, in The Fbrists' Ex- 

 change, Aug. 23, 1919, says: 

 "The propagation of conifers 

 by grafting may refer to either 

 (a) greenhouse grafting, or (b) outdoor grafting.

 stock, a Pereskia, is prepared by cutting 

 out a wedge-shaped piece. C, The cion, an 

 Epiphyllum, is a short branch; a little of 

 the outside is removed from each side of 

 the base. B, the stock and cion fitted

The former is 



without doubt the most interesting mode of culture practiced by 

 the propagator, and good results are always obtained when the 

 necessary operations are carefully and skillfully performed. 



Greenhouse grafting. In the first type the work is carried on 

 in the greenhouse throughout the Winter and early Spring. The 

 reason why the propagation of conifers from greenhouse grafting 

 is so uniformly successful is that the operations are performed 

 inside where all conditions are under control of the propagator. 



The grafting of conifers as a means of propagation is only used 

 with varieties which propagate poorly or not at all from seed or 

 cuttings. Some varieties ofJuniperus virginiana, such as J. glauca, 

 J. Schotti, J. Counarti, and J. elegantissima, together with most of 

 the garden forms of Pines, Spruces and Firs, form a list of the 

 varieties grafted. 



The necessary equipment consists of a greenhouse with the 

 benches built up on both sides to a height of 12 inches. Over the 

 top of the bench a close fitting glass sash is placed. This gives a 

 closed box or grafting bench 12 inches deep, covered with glass 

 sash. Heat is supplied from pipes beneath the benches. 



Stocks for grafting. After the greenhouse with its benches has 

 been properly arranged for taking care of the grafts, the next 

 important detail is securing a supply of seedlings to pot for use as
