General Notes on Lawn Care Products:
In addition, you will find many lawn care products that are packaged in bags that state how much area the product covers in terms of square footage. For example, you may purchase a lawn fertilizer that treats 10,000 square feet or a weed control that covers 5,000 square feet. Square footage of course is determined by multiplying the length times the width in a given area. For example, a 10 x 10 area has 100 square feet.
It is always best if you try to determine the square footage of an area before applying a particular product. This will help ensure that you apply the proper amount of product over a given area. It is particularly important that you not over apply most products. But sometimes it is not easy to calculate the exact square footage of large, irregular shaped areas.
But may people do know the approximate size of their property. For example, they may have a _ acre lot or two-acre lot. Although by no means exact, by subtracting the square footage for the foot print of the house (first floor), the dimensions of the driveway, the garage, all plant beds and any other areas that are not grass, you can get a rough idea of how many bags you might need.
Here is a breakdown on acreage as it translates to square footage:
1 acre = 43,560 square feet
1/2 acre = 21,780 square feet
1/4 acre = 10,890 square feet
