JERUSALEM ARTICHOKE (Helia'nthus tubero'sus) 

 flourishes most in a rich, light soil, with an open exposure. 

 Plant middle-sized tubers, or cuttings of the large ones, 

 one or two eyes being preserved in each. Plant towards 

 the end of March, though it may be performed in February, 

 or even preferably in October. 



Insert by the dibble in rows three feet apart each way, 

 and four inches deep. The only attention necessary is 

 an occasional hoeing to loosen the surface, a little of the 

 earth being drawn up about the stems. Early in August 

 cut the stems off about their middle, to admit more 

 freely the air and light, and in other respects to be bene- 

 ficial to the tubers. 



They may be taken up as wanted during September, 

 and in October, or as soon as the stems have withered 

 entirely, for preservation in sand for winter's use. They 

 should be raised as completely as possible; for the smallest 

 piece of tuber will vegetate and appear in spring. It is 

 for this reason that they are often allotted some remote 

 corner of the garden ; but their culinary merits certainly 

 demand a more favourable treatment.
