grows, should be slightly tied to the portion of the stock left 

 on above the bud, in order to prevent its being injured by 

 high winds. The second year this portion of the stock may 

 be cut off close to the bud. 



In-arching. This is, perhaps, the most ancient of all 

 methods of grafting indeed, it is supposed that the Ancients 

 first learned the art from observing a case of natural grafting. 

 In-arching consists of bringing the branch of one tree or 

 shrub in contact with another ; both branches should be as 

 nearly as possible the same size. A slice is cut off both 

 branches, as nearly as possible the same size and shape, so 

 that the bark of both scion and stock may exactly meet, 

 they are then bound with matting. In-arching should 

 be performed in Spring. As soon as the union takes place, 

 which will be in three or four months, the shoot may 

 be separated from the mother plant. In-arching used to be 

 practised in the propagation of rhododendrons and other 

 hard-wooded plants. These plants are now, however, more 

 frequently propagated by grafting.
