Why are my potatoes growing above ground?

The part of the plant we call a “potato” grows underground. It grows on a specialized underground stem called a stolon.

Create a furrow in the ground 3 to 5 inches deep. Space the potato rows 2 to 3 feet apart. Place the seeds in the furrows 12 inches apart. Cover the rows with fresh soil. Make sure that the planted seed pieces include at least one eye in good condition to achieve crop production.

How soon can you plant potatoes?

How do you raise potatoes?

Pile up a small amount of soil around each planted seed potato, creating a small hill of 1 or 2 inches.
