 should be covered immediately by applying a coat of shellac or white 

 lead and oil. All broken branches, dead and useless wood, should be 

 removed from the tree. 



RAISING OR LOWERING THE GROUND ABOUT TREES 



In grading operations it is often necessary to raise or lower the 

 ground about the tree. There is no way of being absolutely sure that 

 the tree will live if the grade is changed, but if the the best care is 

 given many good trees can be saved from destruction. 



If there is to be a fill about the tree the first step would be to 

 plow the surface soil if, it has become at all hard. This is done to 

 facilitate the passage of water to the roots, which will be much farther 

 below the surface after the grading is done. The filling over the tree 

 should be of light open soil, for heavy clay would be apt to shut out 

 the water supply. If the fill is over 6 inches deep the soil should be 

 kept away from the tree by surrounding it with a retaining wall built 

 1 J/2 or 2 feet away. 



If the ground is to be lowered about the tree, the slope from the 

 old grade to the new should not start nearer the tree than the tips of 

 its branches, if the roots are to remain undamaged. 



WATERING TREES 



The most effective way of watering trees is to supply the water in 

 a fair quantity at the ends of its roots, where it is needed. The ends 

 of the roots are said to be as far away from the trunk as the end of its 

 branches.
