Just before planting, cut away to a smooth surface all torn, bruised, 

 lacerated, broken roots and rootlets with a sharp knife. The cuts 

 should be made from the top side of the root downwards and slanting 

 outwards. This causes the exposed cut surface to face upwards and 

 causes the soil to rest upon it when it settles. "Wounds made in this

Avay heal more rapidly than cuts made in the opposite manner. Even 

 the small fibrous roots should be cut to short stubs, all dead portions 

 being removed. If properly pruned in this manner, there will be very 

 little loss from root rot even in sections where this trouble occurs. 

 Trees that have been grown in deep soils frequently have long tap-roots. 

 They may be shortened to from 6 to S inches for convenience in plant- 

 ing, without injuring the tree. 



HOW TO PLANT 



The hole in which tlie tree is to be set should be dug of suflicient size 

 that the roots may rest naturnlly without crowding or bending. The 

 tree should be set at the same depth, or only slightly deeper than it 

 stood in the nursery row. Fn regions where winter injury is prevalent, 

 growers sometimes plant their trees loaning slightly in the direction 

 of the prevailing wind, or 1o the southwest, so that the shade will 

 protect the trunks from the sun. As an additional protection against 

 winter injury and wind, the heavy side of the tree should be planted 

 towards the 2 o'clock sun.
