32 THE NURSERY. 



Where the tree digger has been run under the 

 trees and the best grade only taken out, the ground 

 which has been displaced and loosened should be 

 immediately firmed again upon the roots. This is 

 done by the use of a heavy one-horse roller between 

 the rows, or it may be done by pressure from the 

 foot if by a heavy man and the work well done. 



Evergreens may be root pruned in this way, 

 which is nearly as good as once transplanting. It 

 should be done just before the beginning of growth, 

 or if the season is favorable it may be done just at 

 the end of the growing season, as the roots will 

 continue to grow nearly all summer while the tops 

 are at rest.
