How far apart to plant sweet potatoes

Plant sweet potatoes 12 inches apart within a row and space the rows 40 inches (at least 3 feet) apart.

The spacing: 12 inches between plants within a row, and 40 inches (at least 3 feet) between rows.

Planting in ridges of loose soil 8-12 inches high lets the soil warm faster in spring.
Ridges improve drainage and give the roots room to expand.
If you only plant a few sweet potatoes, mounded hills of soil work well too.

Spacing varies by variety and layout; your local extension office is the closest authority.
