Difference Between Nursery Stock and Material Gathered 

 FROM THE Wild. Trees and shrubs in nurseries are so cultivated and 

 transplanted that their roots make a symmetrical growth. The roots 

 are thus short and branching because they search equally on both 

 sides of the row for food. In the case of forest specimens they may 

 have to go several feet for an opportunity to get food; furthermore, 

 the only opportunity for food may be in one direction. The roots 

 are often very long and unbalanced, and when the trees are|dug the 

 roots are seriously shortened. The precaution in using material 

 from the woods should be to carefully prune the tops proportionately, 

 supply water and give extra, painstaking treatment.
