Cultivation. — For winter and early spring crops, in the mid- 
dle and northern parts of the United States, sow about the 
end of August, and again about six weeks after. For sum-

April, and continue sowing until the middle of May. The seed 
may be sown broadcast, or thinly in drills a quarter of an inch 
deep, and nine inches apart. 
It will succeed in any common garden soil, but the more it 
has been previously enriched by manure, the better, and the 
more vigorous will be the crop. The seeds will come up in ten 
or fifteen days after sowing. If the young plants grow too 
thick, they should be thinned out as soon as they have three 
or four leaves an inch in breadth. No further cultivation will be 
required than to keep down the weeds.
