Find an appropriate planting site. Make sure the soil is well drained and loose with a soil pH of 5.0 to 6.0 Fertilize it with the nutrients that it needs so it is at a balanced level for growing potatoes. Send a sample to a professional laboratory for testing if you are not sure what the soil needs.
Place the seed potato in a lit area at room temperature for a few days and check at intervals for sprouts from one of the "eyes" on the skin. The potato is ready to plant when sprouts appear.
Cut the potato into 1 1/2 to 2 oz. pieces or as small as an egg. Make sure each piece has an eye.
Dig furrows in the soil that are 36 inches apart and up to 3 inches deep. Place the potato pieces 10 to 12 inches apart in the furrow with the cut side down. Cover them with soil.
Add 3 inches of soil to the top of the soil when the sprouts appear to protect them from the sun. Apply fertilizer five inches away from the plant on either side and about 2 inches deep. Apply enough water to keep the soil moist as the plants grow.
Harvest the plants approximately 115 days after planting. Dig up the tubers carefully to avoid damage.
