I have a plot that is approximately 270 square feet and I want to plant sweet woodruff. The plants I have access to are in 4 1/2 inch pots now. How many plants will I need for a good ground cover of the area?
The number of plants per sq.ft is normally determined by the spacing between plants. On average, sweet woodruff plants are spaced between 9 and 12 inches apart. Here is more information: http://www.penderpines.com/plant-care/flower-beds/
