STRAWBERRIES 



Strawberries may be grown in any good garden soil 

 that is light and fertile. The plants may be set out in 

 midsummer, fall, or spring. Strong ones transplanted in 

 July or August will give a full crop of fruit the next 

 season. They may succeed potatoes, onions, or any of 

 the early vegetables. 



Some varieties of strawberries bear both stamens and 

 pistils and are known as " perfect flowering plants," 

 while others bear pistils only and are known as " pistil- 

 late plants." The pistillate forms must have perfect 

 flowering plants growing every eight or ten feet in the 

 row, to pollenize their blossoms.
