Use the following chart to calculate how many plants / flowers are required to fill a specific area / space / flower bed.
| Desired Plant Spacing | # of Plants Needed Per Sq. Foot * |
| 6” | 4.61 |
| 8” | 2.60 |
| 10” | 1.66 |
| 12” | 1.15 |
| 15” | .738 |
| 18” | .512 |
| 24” | .290 |
| 36” | .185 |
* Multiply sq. ft. of bed by # in this column
Example:
If your bed is 10′ x 20′, then the area is 10 x 20 = 200 sq. ft.
If the plant / flower spacing is 12″ on center then 200 x 1.15 = 230
You would need 230 plants to fill this area.
