CERTIFIED SEED POTATOES 
From the Rugged North 
Potatoes do best in a loose, well-drained soil. The early crop can be planted in April. The crop 
for winter storage should be planted the first half of June. With rows 30 inches apart and the 
hills 12 inches apart in the row, 20-22 bushels of seed plant an acre. For the garden, a peck of 
seed plants about 200 hills. Remember that Potatoes need to be sprayed or dusted to insure 
good yields. 
Plant 2% to 314 inches below surface soil.
