How to prune 



The limb should be cut close to the main stem with a 

 smooth, even cut. No long stubs should be left. Care 

 should be taken not to let the limb break off when partially 

 cut and skin the main stem. This can be prevented by 

 cutting a little on the underside first. When the limb 

 has been removed, the wound should be covered over with 

 grafting wax, tar or white lead to prevent the entrance 

 of fungi spores. Pruning is best done in the early spring 

 before growth starts. 



ORNAMENTAL TREES 



Entire books have been written on the arrangement of 

 trees in ornamental planting and only the briefest mention 

 of the most important points can be made here. In the 

 first place it must be remembered when a tree is planted 

 that it is going to grow, and due allowance must be made for 

 its ultimate size. Do not plant too close to the house or 

 porch. Never plant directly in front of a window unless 

 for the purpose of blocking some unattractive outlook. 

 If there is any good view or object of interest in the vicin- 

 ity, bear it in mind and keep the view of it open. If there 

 is any objectionable view, blot it out. Always keep an 

 opening or two to the main road and the approach to the 

 house. Too many trees are better than too few; they 

 can easily be cut out. Some open lawn is desirable ; do 

 not scatter trees everywhere, group them or bank them 

 around the edges. If the shape of a tree is its chief beauty, 

 place it in the open where it may be seen to advantage. 



The following tables give the characteristics and uses 

 of our more important ornamental trees.
