How far apart to plant potatoes

Plant potato seed pieces 6 to 8 inches apart in the row when you want smaller tubers in greater numbers, with rows 32 to 40 inches apart.

The spacing: In-row spacing of 6 to 8 inches (close spacing used to reduce tuber size and increase the number of tubers set), with row spacing of 32, 36, or 40 inches.
Spacing varies by variety and layout; your local extension office is the closest authority.
