SHADE TREES AND E \ E R C. R E E N S 



WHY FOREST TREES WILL NOT DO 

 FOR HOME PLANTING 



Three main essentials are involved in the growth 

 of every tree — Hght, plant-food and rrxjt-space. 

 A tree grows straight up if it has plenty of Hght 

 and winds do not blow it over. When it has plenty 

 of plant-food, it develops and enlarges regularly 

 on all sides by even stages, and makes a sym- 

 metrical trunk and head. If the roots have soil all 

 around, they form an even network about the tree. 



In the nursery all these conditions are made per- 

 fect. The trees develop smoothly and make 

 perfect specimens, evenly developed on all sides, 

 trimmed into proper shape, with a straight trunk. 

 They are full of vitality. In getting ready for 

 transplanting, they are root-pruned several times 

 before you get them. This takes the form of 

 cutting the roots sometimes, and other times 

 entire taking up and replanting. In any case it 

 results in the forming of immense numbers of hairy 

 feeding roots that take hold quickly anywhere. 

 Such prepared trees seldom die when moved. 



Now w^ith forest trees, the conditions are very 

 uncertain. There may be a rock right at one side 

 of the tree, causing the roots to grow to the other 



rUpper) Shows what splendid trees Norway Maples are. Remember 

 that such perfect trees cost only about $i each when 9 feet high. Lower) 

 A schoolyard fully shaded by about eighteen maples, costing $15 in large 

 size. The children can be taught to take care of such trees and hedge.
