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.
