GRAFTING- AND BUDDING.

or on a branch of the stock, either between the bark and the 

 alburnum, or into the albnrnnm itself, the bark in no case 

 being removed, 



Side-Grafting under the Baric. — General Directions. 

 When it is desired to graft a branch on the side of a stem 

 and under the bark, the stock must be in a state of vegetation, 

 and the operation is performed either in April or May, at the 

 flow of the sap, when it is said to be done with a shooting 

 bud ; or from July to September, when it is termed a graft 

 with a dormant bud. In the first case (with a shooting bud), 

 we use scions of the previous year, which have been laid in at 

 the north side of a wall or in a cellar to preserve their vitality, 

 and, the sap being in motion at the time they are used, the 

 graft will develop itself in the course of the same year. In the 

 second case (with a dormant bud), in which the graft will not 

 develop itself until the year following, scions of the current 

 year are used, cut on the day of grafting. If they are deci- 

 duous kinds, the leaves are cut off. We have said before, that 

 scions of evergreens should not be cut till the last moment, 

 and are not to be stripped of their leaves. In both of these 

 methods the tops of branches with a terminal bud form excel- 

 lent scions. There are two systems of side-grafting under 

 the bark, one in which the scion is simply a piece of a 

 branch ; in the other, it is a branch cut from the parent, with 

 a heel or strip attached to the base. 



Side-Grafting with a Simple Branch. 

 This process is valuable for the restoration of defective trees, 

 in supplying branches where they are wanting, and for grafting 

 a new variety on aged subjects. It is equally of use in pro- 

 pagating plants. The woody scion will answer better for 

 insertion under old bark than the shield-bud commonly used.
