Cauliflower spacing and mature footprint

Space Cauliflower 18 inches apart, measured center to center (45 cm).

The mature spread is about 2 ft (60 cm), so plants set at that distance grow together into a closed canopy over the bed.

Treat 18 inches as a planning baseline — cultivar and local growing conditions shift the final footprint.

Three plants set 1.5 ft apart, center to center; shaded circles show the 2 ft mature spread.
