HOW MANY PLANTS DO I NEED?

When figuring out how many plants you will need to fill a landscape bed, first figure the square footage of the area. Next check the mature spread of the plants you will be using and find an average. Use that number to find the multiplier on the table below. Choose spacing based on how fast you want to cover the area and/or the mature width of the plant selected.

EXAMPLE: A 5′ x 10′ garden bed is 50 square feet. If I am planting perennials with a spread of 18″ and I want to plant in a triangular layout I need to multiply .51 x 50, which gives me 25.5 plants which I can round up or down. A square planting pattern would be .44 x 50 with a total of 22 plants needed.
