 forking up the ground breaks many of the roots, 

 requires much labor, and the result is not beautiful. 

 A mulching of leaves is not offensive even in winter 

 when stems are bare, and the decay of this mulch 

 will usually produce sufficient plant-food. Even 

 when additional food is required, there are ways of 

 administering it without disfiguring the surface of
