Pot 'herb crops, or greens, are groivn for their 

 leaves: therefore they must mahe quick growth in order 

 to be crisp and tender; the ground must have good sur- 

 face tilth and much available plant-food; the application 

 of soluble nitrogenous substances is usually important, 

 particularly when the groivth is nearing completion. Most 

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

 them are partial -season crops, and are therefore treated 

 as succession- or companion -crops. 



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

 drills. It is usually a succession -crop. 



Spinach or spinage is the standard plant for spring 

 and fall greens. For home use it ma}^ be had during 

 the summer by making suceessional sowings in rather 

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

 not grown in warm weather. Formerly spinach was
