Ground Cover Calculator Guide
How many ground cover plants do I need for my project? Use this guide to calculate your planting needs.
​
For planting ground covers like pachysandra and vinca minor (myrtle), we recommend planting either 6" on center or 8" on center spacing.
PLANT COVERINGS FORMULA
​
Square Feet x Plants Needed Per Square Foot = Total Number of Plants Needed
​
​
Plant Covering Calculation Example
​
Find the number of myrtle plants needed to cover a 15 ft. x 5 ft. hillside, planting 6" on center.
​
Length x Width = Square Feet
15 ft. x 5 ft. = 75 sq. ft.
Square Feet x Plants Needed Per Square Foot = Total Number of Plants Needed
75 x 4 (From Chart Below) = 300 Plants Needed
​
These calculations demonstrate that 300 plants will be needed to cover a 5 ft x 15 ft. area with plants spaced at 6 inch centers.
