Estimating Fertilizer Needs

The best way to determine the amount of fertilizer you will require is to determine the surface area of your lawn. Measure the length and width to compute the square footage.

If you cannot do this, then try to guess the area as accurately as possible. As a guide, every 8 steps are roughly 10 feet of space. Walk from one side to the other on the width and length.

For triangle lawns, determine the width and length of the triangle. Multiply them and then divide them by 2. For circles, find the center and then walk out of the circle to the edge. Multiply by 3.14.
