Answer #1 ·'s Answer · Determining the number of plants you need to fill a given area in a landscape is pretty easy, granted you will be filling the space with the same variety of plant. First you have to calculate the square footage of the area you intend to plant.

SQUARE AREAS - For square or rectangular areas multiply the length of the area by the depth of the area. For example, if the area you intend to plant is 50 feet long by 50 feet wide you would have 250 square feet (50 x 50 = 200).

CIRCULAR AREAS - These areas are a little more difficult, but not too hard. Start by multiplying the radius of the circle by itself, then multiply that figure by 3.14. The radius of a circle is the point from the center of the circle to the outside edge of the circle. So, if the radius of your circular area is 10 feet you have 314 total square feet. The equation would look like this: 10' x 10' = 100 feet...then, 100' x 3.14 = 314'.

When you have determined total square feet there are a couple basic charts you can refer to to determine how many total plants you need to fill the area. Here's a link to a page in Gardenality that shows these charts (copy and paste the link to go to the page):
