How to Grow Sweet Potatoes: A warm, well drained, 
sandy loam is the best land for sweet potatoes. After plow¬ 
ing and harrowing thoroughly, lay off rows 3 feet apart and 
drill 500 to 1,000 pounds of commercial fertilizer containing 
plenty of potash but not much nitrogen. List on the fertilizer, 
and knock off the top of the ridge. Set the plants 15 inches 
apart. Cultivate thoroughly until vines begin to run. Harvest 
when mature or when frost kills the vines. Store in a warm 
cellar or building where the temperature does not go below 
50 degrees.
