Sea Buckthorn spacing and mature footprint

Space Sea Buckthorn 6 ft apart, measured center to center (1.8 m).

The mature spread is about 10 ft (3 m), so plants set at that distance grow together into a connected screen.

Treat 6 ft as a planning baseline — cultivar and local growing conditions shift the final footprint.

Three plants set 6 ft apart, center to center; shaded circles show the 10 ft mature spread.
