Answer: You may find that using cut seed potatoes instead of individual seed potatoes will increase the number of potatoes per plant, but they will be smaller. To increase the overall yield, make sure the plants are in full sun and in good soil. The soil should be well prepared with plenty of organic matter and it should be rich; the pH should be around 6.0. Keep the soil evenly moist up until the flowers fade. Finally, make sure the potatoes are well covered all season. You can grow them in a trench and cover them gradually for about the first month so that a mound about a foot high builds up, or you can grow them on the surface and slowly cover them to about a depth of two feet. You might also consider trying a different variety and see if it does better for you.
