No. 4.] MARKET-GARDEN CROPS. 153 



A small application of nitrate of soda to late fall spinach will keep 

 it from turning yellow. 



To winter over spinach in the field sow on well-drained land, 

 rather thickly, from September 1 to 12. When cold weather comes, 

 and in any event by December 1, cover with sedge, straw or fine 

 boughs, for the winter. In early spring, March or April, remove 

 the covering, and treat with sulfate of ammonia, hoed in. Spinach 

 will live over on some land with no protective covering. It will be 

 found a profitable crop for most market gardens.
