If you don’t see your coverage area on the chart, 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

On occasion, you may need a spacing multiplier that is not on our chart. Use the following formula to figure the multiplier for your situation:
Multiplier = 144/x², where X = the spacing distance in inches you need

Example: If you need a spacing of 20 inches, your multiplier would be:
144/20² = 144/400 = multiplier of 0.36

These are general suggestions for planting. If you want to make a greater show in your planting before your plants have had time to grow to their fullest, then you might need to add more. If you want a fast spreading plant to keep from filling in too fast, then you might want to not plant as many.
