 of soluble nitrogenous substances is usually important, 

 particularly when the growth is nearing completion. Most 

 pot-herb crops demand a cool season; and nearly all of

 as succession- or companion -crops. 



SPINACH 



Spinach is essentially a spring and fall crop. It de-

Spinach or spinage is the standard plant for spring

 cool and moist ground; but as a commercial crop, it is 

 not grown in warm weather. Formerly spinach was
