196 PRODUCTIVE FARMING 



If the crops follow one after another it is succession* 

 cropping. Such crops must mature quickly. Early peas or 

 radish or lettuce may be followed by tomatoes, late cabbage 

 or celery. 



If the crops are grown together in the garden for all or 

 part of their time the system is called companion-cropping. 

 One of these crops matures early and the other is started 

 between the rows before the first crop is harvested (Fig. 100). 

 An example would be early onions with cabbage. With 

 some vegetables both the crops may be drilled in the row

together, as when radishes and beets are planted. The 

 radishes are harvested by the time the beets need the room. 

 Early and late celery may be grown together. When the 

 first crop is sold the late crop is ready to use all the space. 



Storing Vegetables. Vegetables of several kinds may 

 be stored for winter use. Onions should be well dried before 

 storing. They are to be handled without bruising, and are 

 spread in single layers on open shelves in a dry place where 

 they will not freeze. 



Celery and cabbage may be transplanted to a cold cel^* 

 before the ground freezes. Keep the soil moist about the 

 roots and they will keep all winter.
