HORTICULTURE, 47 



Citrus trees in the lower Rio Grande, W. C. Griffing (Tex. Dept. Agr. BuL 

 16, 1010, PI). 259-26^). — A pajier oa this subject with a discussion following. 



The author concludes that citrus treey budded on Citrus trifoliata stock will 

 not thrive on the silty, loam soils of the Rio Grande Valley. A Sour orange 

 root is recommended as the proper stock in that section. Since the Satsuma 

 does not thrive on the Sour orange root, it can not be profitably grown in the 

 valley. Other varieties of the Kid Glove type of orange, however, make good 

 growth and fruit prolifically on Sour stock. 



The author concludes that most of the danger from freezing can be eliminated 

 by maintaining continuous and vigorous growth during the summer months 

 and by withholding irrigation and planting cover crops to draw the moisture 

 from the soil during the winter months.
