I just started to dig my potatoes and most of them are very small. I have some as big as a baseball and all of them look nice. I got about 40lbs out of one row but only 5lb are as big as you would buy at the store. Any Help!! Thanks Potato Man. Ps 8th yr growing them.
There are several reasons for undersized potatoes. Three being, lack of uniform watering, not enough calcium, and not enough room to develop.
