Spacing Multiplier 9.0 4.0 2.28 1.44 1.0 0.64 0.44 0.25

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 13.5 inches, your multiplier would be:
144/13.5² = 144/182.25 = mulitplier of 0.79

General 'Suggested Spacing' Guide

** Adjust spacing based on desired coverage time and budget **

2¼" & 4" pots Liriopes 12"
4" pots   Daylilies 12" - 18"
Ferns/Hostas 12" - 24"
Ivies/vines 12" - 18"
72-cell packs  Spicata 10" - 12"
Mondo 8" - 10"
One gallons Most plants 18" - 24"

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.
