use the following formula to calculate how many plants you will need:
(Area in sq. feet) x (Spacing Multiplier) = Number of plants needed
Finding Unknown Spacing
Multiplier
For other spacing
requirements, use the following formula to figure your multiplier:
Multiplier = 144/X2 where X = the spacing distance in inches you need
Example: If you need a spacing of 13.5 inches, your multiplier would be:
144 = 144 = mulitplier of 0.79
13.52 182.25
