escaping. This should not be put on more than two or 

 three inches in thickness, for if too thick it causes the roots 

 to grow near the surface, when they would be more liable 

 to injury during the winter or in extreme dry weather. 



Keeping up an After-growth 



When the trees are planted, it must not be expected that 

 the end of one's work has come, for unless the soil is naturally 

 very rich or is made so by heavy manuring at planting, trees 

 will not continue to grow without some additional plant 

 food each year. When planted on the lawn, if the grass is 

 clipped once or twice each week and liberally dressed in the 

 fall or spring, little or no further fertilizing for the trees 

 may be needed; but even under this condition a mound of 

 manure banked against the trunks before the ground freezes 

 in the fall will be of great protection to the collar or crown 

 of the roots. This method of manuring trees in poor soil 

 is advisable, a liberal supply being used, and in the spring 

 spreading it around on the lawn about the trees. Com- 

 mercial fertilizers, like ground bone and potash, fish and 

 potash, or even the specially prepared fruit-tree fertilizers, 

 may be successfully used. 



The Arrangement of Trees 



Trees are arranged or grouped together in ornamental 

 gardening to accomplish the following results: for shelter 

 from cold winds, for screens to shut out objectionable views, 

 and in groups alone or combined with shrubs and the lawn 

 for ornamental effect or to serve as a background for or 

 setting to the house, thus completing or finishing the home- 

 picture.
