Culver's Root spacing and mature footprint

Space Culver's Root 2.5 ft apart, measured center to center (75 cm).

The mature spread is about 3 ft (90 cm), so plants set at that distance grow together into a solid mass.

Treat 2.5 ft as a planning baseline — cultivar and local growing conditions shift the final footprint.
