"hollow heart" is a discolored hole in the center of a healthy potato. It is caused by over-watering. You can dig it out and eat the rest of the potato. Irregular watering causes misshaped and knobby potatoes.
Potatoes need full or partial sun and a loose, well-draining soil that is not too rich. A soil pH between 5.0 and 5.5 with liberal amounts of fertilizer and a steady water supply.
