Principles of Plant Culture. 



Fig. 133 shows the roots of a tree properly planted. 

 The hole was dug sufficiently large so that the roots were 

 readily placed in it without crowding, and the soil was 

 so well woiked in among the roots that it comes in con- 

 tact with their whole surface. 



Fig. 134 shows the roots of the same tree improperly 

 planted. The hole was dug so small that the roots were 

 necessarily crowded out of their natural position, and 

 the earth was thrown in so loosely that it comes iu con- 

 tact with only a part of the root surface. Distortion of 

 the roots of trees and shrubs at planting may cause 

 injurious root galls. 



In planting trees of which the 

 roots are not already inclosed in 

 soil (403), the hands should be 

 freely used to bring the soil in con- 

 tact with the whole root surface, 

 and the earth should be moderately 

 packed about the roots with the 

 feet, or otherwise. 



If the soil is dry, it is probably 

 better to moisten it before placing 

 it about the roots, rather than after, 

 as we have then a better opportunity 

 to judge of the quantity of water 

 required, and the soil is less likely 

 to settle away from the roots. 



Trees of considerable size 

 should generally be staked 

 or otherwise supported after
