be placed about the roots in order to provide the nourish- 

 ment needed by the tree. 



Spacing on the street should receive more careful atten- 

 tion than is ordinarily given. Knowledge of the usual spread 

 of the crown will determine the distance of planting. The 

 branches of adjacent trees should not touch but there should 

 be a little space between the crowns. This is necessary to 

 prevent the grass from being killed and also keep the soil 

 beneath the trees from remaining damp after rains. 



Of equal importance with the spacing along the street is 

 the arrangement in the parking strips. Ordinarily trees 

 should be planted along the streets at equal distances from 

 the sidewalk and curb. This will allow the roots plenty of 

 room in which to grow and not interfere with either. When 

 trees are planted too near, the roots often raise the walks or 

 push the curbing out of position. 



Trees may be planted at any time after the fall of the 

 leaves in autumn and before the opening of buds in spring. 

 In regions subject to severe winters it is best to delay plant- 

 ing until spring. The freezing and drying out of the soil 

 during the winter is quite liable to injure the roots of trees 

 planted in the fall. 



When trees are planted they should be protected by 

 stakes to prevent swaying by the wind, which loosens the 

 roots and causes the trees to lean. A guard should also be 

 provided to shield young trees from the bites of horses and 

 prevent other injuries to the stem.
