In cutting seedlings, it is always advisable to cut and 

 throw away the blossom end of the potato ; that is, the bud- 

 eye cluster. This end, when planted, is more liable to cause 

 prongy tubers, although the tubers produced from this end 

 are more disease resistant. 



In order to insure a good development during the first 

 year or season's planting of the potato seed, it is advisable 

 to allow the seedling a long growing period. They require 

 from five to nine months, depending on all conditions. It is 

 well to plant as early as possible, if planted in the field.
