TRIMMING WHEN SETTING

136). Never cut downwards on a limb, for 



a ragged wound nearly always follows. 

 "In fall -set trees it is 



generally inadvisable to 



prune them before spring 



(unless the tops are so 



heavy and the bodies so 



weak that they are likely 



to be injured by wind), 



because the cut surfaces 



are likely to dry out. The 



roots of the tree are not 



yet sufficiently established 



in the soil to supply the 



added evaporation which 



takes place from the 



wounds. If it seems to 

 be desirable to 

 trim the trees 

 when they are 

 set, they should 

 be cut back 



only part way. They may be cut 

 again, to fresh wood, in the spring."

ticular questions of practice. The ex-
