Seed Use only certified seed potatoes. From 1,200 to 2,000 pounds of Irish potatoes seed are required to plant an acre for commercial production. Spacing Plan your rows 36 to 38 inches apart. Place seed pieces 6 to 8 inches deep and 9 to 10 inches apart within the row. The Irish potato is a cool-weather crop.
Early planting is necessary to give maturity before it becomes too hot.
Plants can withstand light frost, but hard frosts can severely damage plants. It is difficult to get a good stand for a fall crop due to high soil temperatures at planting. Distribute the fertilizer in a 2-inch band to the side and slightly below the seed pieces. Follow label instructions. Maintain bed height.
