Radish spacing and mature footprint

Space Radish 2 inches apart, measured center to center (5 cm).

The mature spread is about 4 inches (9 cm), so plants set at that distance grow together into a closed canopy over the bed.

Treat 2 inches as a planning baseline — cultivar and local growing conditions shift the final footprint.

Three plants set 0.16 ft apart, center to center; shaded circles show the 0.3 ft mature spread.
