Area Calculations: Draw your site as accurately as possible - graph paper works well. For odd or complex shapes, divide the area into combinations of rectangles, triangles, and/or circles. Use the following formulas to determine area:

Rectangle: Area = length x width

Circle: Area = 3.1416 x the square of the radius (radius is the center of the circle to the edge.

Triangle: Area = 1/2 x length of base x length of height

To determine topsoil requirements for areas of varying grade, use a transit to indicate exact fill requirements...or estimate an average fill depth. Usually soil does not have to be ordered all at once so you can always bring in more...better too little than too much!

Mulching is one of the most important ways to maintain healthy landscape plants. A mulch is any material applied to the soil surface for protection or improvement of the area covered.
