THE TIlMi: TO PLANT. 



Trees should be planted when they arc in a dorinant state or jusl 

 as they start into growth in the spring. Very hardy deciduous trees, 

 such as the Elm, Cottonwood and Ash, can often he successfully moved 

 in the fall, if the ground is moist at the time of removal, but great care 

 must be taken to work the soil in compactly about the roots so that there 

 will be no large air-spaces between them. If the trees are large they 

 should be tied to a strong stake to prevent their being blown about by 

 the wind. 



Large trees are sometimes successfully moved in the winter because 

 a large ball of frozen earth may be taken up with the tree. Before the 

 ground freezes in November, dig a trench about the tree deep enough to 

 cut most of the roots. Fill the trench with straw and, when the ground 

 is frozen, move the tree with the large ball of earth to the hole previously 

 dug to receive it. 



Evergreens should be transplanted early in the spring when the 

 ground is moist. 



HOV\f TO PLANT. 



Distance Apart. — On rich, loamy soils the large trees used for street 

 planting should be placed forty feet apart. In dry, stony, or sandy soil, 

 twenty-five or thirty feet is far enough. The smaller trees may be planted 

 closer. 



Digging the Holes. — The hole should be dug large enough to take 

 the roots of the tree without crowding, and deep enough to allow the 

 tree to set a little deeper than it was before. Loosen up the sub-soil in 

 the bottom of the hole and put in some fine, rich top soil before putting 

 in the tree. 



Planting. — Great precaution should be taken to prevent the roots of 

 the tree from becoming dry while planting. If they are received some- 

 time in advance of planting, unpack them and "heel" them in, i. e., bury 

 the roots in earth until ready to plant. When the cells in the roots of the 

 tree have once become dry, it is very difficult for them to absorb water 

 from the soil and start the current upward which supplies the leaves and 

 growing shoots. 



Cut off all the injured and broken parts of roots with a sharp knife. 

 If a smooth cut is made, a callus forms readily, and above it are produced 

 the fine, fibrous feeding roots.
