Calculating Plant Coverage: How Many Gazanias for 406 Square Feet?

Spacing Depends on Desired Look

There's no universal "flat coverage" rule because plants spread differently. For gazanias, which don't spread widely:

• Dense, full coverage: Plant 8–12 inches apart on center.
• Visible soil between plants: Space 18 inches apart on center.

A standard 12×12-inch flat typically holds 16–18 plants. At 12-inch spacing, each plant covers roughly 1 square foot. For 406 sq ft at 12-inch spacing, you'd need about 406 plants—roughly 23–25 flats. Adjust based on your preferred density.
