How deep to plant potatoes

Plant potatoes 4 inches deep, about 1 foot apart, in a furrow or shallow trench.

The depth: Set seed pieces, cut side down, and small whole potatoes about 1 foot apart in a furrow 4 inches deep; in excellent potato-growing soil you can instead plant seed potatoes 7 to 8 inches deep and skip hilling or deep mulching.

Potatoes prefer loose, well-drained, fertile, slightly acid soils.
Potatoes perform best in acid soil with pH 4.8 - 5.5.
Potatoes prefer well-drained, light, deep, loose soil, high in organic matter.
Set seed pieces cut side down, and small whole potatoes about 1 foot apart.

Planting depth varies with soil type and variety; your local extension office is the closest authority.
