Plant Calculator
Use our handy calculator to determine the appropriate number of plants needed for an area. To calculate the approximate volume needed to fill or cover an area, use our hard goods calculator.
Note: Actual plants needed may vary slightly.

How to determine the number of plants needed:
Total Area (SF) x Spacing Multiplier = # Plants Needed
Example:Â
Square Pattern
18" Spacing: 1,000 SF x 0.44 = 440 Plants
Triangle PatternÂ
18" Spacing: 1,000 SF x 0.51 = 510 Plants
Square Pattern
18" Spacing: 1,000 SF x 0.44 = 440 Plants
Triangle PatternÂ
18" Spacing: 1,000 SF x 0.51 = 510 Plants
