FRITIT TREES. 



at E. The new extension of the main stem must be cut 

 at about 24 inches above the spring of the upper side 

 branches at A, so as to obtain, by means of the buds 

 B and C, a new set of side branches. A new series of 

 side branches may from this period be obtained every 

 year ; for the lower side branches have now acquired 

 sufficient strength to draw to themselves all the sap 

 which they require for their continued growth. The 

 summer treatment is the same as before. 



Fifth Pruning. — A third set of side branches have 

 grown during the preceding summer (fig. 118). The 

 new extensions of the side branches must be cut back 

 as in previous years. The main stem must be cut at A, 

 and a new set of side branches obtained from the buds 

 C and D. The remaining treatment as before. 



The operations we have described must be continued 

 from year to year, in order to obtain new side branches 

 and regular extensions of them, until they acquire the 

 desired length, when their ends must be directed up- 

 wards, as shown (figs. 84 and 89), until each of them 

 attains the summit of the wall. Towards the tenth or 

 twelfth year the trees treated in the manner we have 

 described will assume the aspect of fig. 84, with this 

 difference^ that the fruit-branches are distributed on 

 each side of the wood-branches, as shown at fig. 118. 



Nailing up, — If it is not wished to fasten up the 

 branches with list, as described at p. 104, it may be 

 done by forming a trellis. It is necessary to fasten up 

 not only the wood-branches of peach trees, but, as we 

 shall see further on, the fruit-branches after the winter 

 pruning and the lateral shoots during the summer. As
