Adult Orange Trees of Sickly Vegetation. The 



Cultivation of 



Orange trees the produce of which is scanty and the Citrus Fruits 

 vegetation sickly and affected by chlorosis are distinctly bene- " ~ 

 fited by the application of a full dressing of nitrate of soda. 

 The following are the constituents of a suitable fertilizer 

 per acre of the grove: 



Nitrate of Soda 700 pounds 



Superphosphate of lime, or Basic slag 350 " 



Sulphate of potash 200 " 



Sulphate of lime 300 ' 



Sulphate of iron I 50 " 



Both with this class and with old trees, once they have 

 recovered themselves and regained normal development, the 

 total quantity of the fertilizers should be diminished by 15 

 or 20 per cent. 



Trees Producing Much Wood, Foliage and 

 Flower, but^Little Fruit. 



Until of late years it has been the practice to dress such 

 trees exclusively with phosphates and potash salts, it being 

 generally believed that nitrogenous manures increased the 

 tendency to defective fructification. 



Careful observation has led to this view being discarded. 



It is rare to find an orange plantation that does not con- 

 tain trees of this character, which, whatever dressing and 

 cultivation they may receive, continue to bear scantily. 

 Recourse is now usually had to re-grafting, or "working- 

 over", and the abundant yields frequently obtained by this 

 means afford proof that some other cause than food defi- 

 ciency had induced the partial barrenness. 



Mandarin Oranges. 



This variety is a greedy feeder and requires an ample 

 supply of manures ; but, as it is of less size and yields smaller 

 crops than the ordinary species, it requires proportionately 

 reduced quantities of the several fertilizers. When in full 

 bearing, mandarins should receive, per acre, fertilizers in 

 accordance with the following formula: 



Nitrate of Soda 450 pounds 



Superphosphate of lime 500 ' 



Sulphate of potash 100 "
