root growth. The chief aim the first season should be to 

 produce plants with strong, vigorous roots, which will 

 attain such a size and depth as will not allow of their being 

 disturbed during the following winter. If successfully 

 carried through the first winter, the roots will become suffi- 

 ciently strong and vigorous the second year to make the 

 crop practically permanent. After the first year or two, 

 good crops may be grown mainly by the use of mineral 

 fertilizers. This crop should not be grown on heavy, 

 compact soils, nor where there is liable to be standing water 

 on the soil during any portion of the year.
