self -blanched ; but it is more subject to disease and the 

 product is often of poorer quality than when given more 

 room and blanched by banking with earth or by collars. 



Cabbage. All cabbages are best grown from trans- 

 planted seedlings that have been grown from 8 to 10 

 weeks in a hotbed, cold frame, or outdoor seed bed. For 

 early cabbages, transplant to the garden as soon as the 

 danger of severe frost is over. For late varieties, trans- 

 plant in June or July in the northern states and some- 

 what later southward. In the plot of cabbages shown 

 in Figure 142, several varieties of early and late cabbages, 

 together with cauliflower and Brussels sprouts, were 

 planted at the same time. 



In many parts of planting zones D and E, cabbage can 

 be grown, or at least left outdoors, over winter. In 

 the climate of northern Louisiana, the seedlings for the 

 spring crop can be reared in cold frames from seed sown 

 in November or December and transplanted in February ; 

 in this way the crop is harvested in April and May. 

 Sweet potatoes may then be grown on the same plot, as a 

 succession crop. Treated in this way in the South, the 

 growing period of such a variety as New or Early 

 Jersey Wakefield is from November i to May i. 



Plantings of early varieties, such as Early Jersey 

 Wakefield, yield heads in about 90 days, or early in July 

 in the vicinity of New York City if planted about 

 April i ; but the heads do not " keep " long in hot 

 weather. It is an excellent plan to plant from 5 to 10 

 plants each of several early and late varieties. For 

 general culture, the following varieties are excellent: 

 Early Jersey Wakefield and Charleston Wakefield for early
