(2) Depth. By " depth," is meant the depth of the soil which 

 is capable of being penetrated by the roots. According to Hesse 

 (p. 6), the following species are content with the depth of 

 soil indicated. Of course, other conditions being suitable, all 

 species will flourish on deep soils ; and, when this is the case, the 

 greater the depth to which the roots penetrate, the greater the 

 height-growth.
