 complete pollination. A few named varieties are propagated by 

 budding and grafting, but seedlings are most commonly planted. 

 The trees become very large and should be grown forty feet or 

 more apart. The soil should be a deep loam with good under

 allowable. 



Figs are grown for home use along the Atlantic coast as far 

 north as Philadelphia, and in the lake region of Michigan. In the 

 interior the trees must be laid down and protected in winter. 

 Commercial orchards are grown along the coast southward from 

 Norfolk and west to Texas. They are abundantly grown by irri- 

 gation in New Mexico, Arizona, and California. 



The fruit is most generally known in our markets as dried figs, 

 but the fresh fruit is becoming more popular. It is rich in sugar 

 and is easily preserved in cans to be shipped to market.
