incisions become widened and heal (I, I, see p. 214), and the 

 buds form branches. The incisions have this advantage over 

 the notches that the bark is not cut across nor the alburnum 

 exposed, but they do not stimulate a sluggish bud so well. 



When there are no buds to be treated in this way, grafting 

 alone will supply the deficiency. Shield-budding would not 

 answer on old stems, as the condition of their sap would not 

 permit the bark to be raised when the scion-branches were 

 sufficiently ripened for budding. On the other hand, herbaceous 

 scions may be grafted by approach in spring. If the operation

is postponed till after July, the union of the graft will be less 

 certain and the future branch will want solidity. Ordinary 

 approach-grafting (see p. 42), and inarching (see p. 44) are 

 employed with equally good results. 



Let us take the case of a peach-tree. It is well known 

 that the anticipative shoots are not always furnished with 

 buds at the base which facilitate the mode of pruning 

 necessary for this tree. Pinching the leaves will, to a certain 

 -extent, remedy this deficiency. Thus the branch (H) (see 

 above) having been inarched (see p. 46) on the branch (G)
