BULK QUANTITIES FOR LANDSCAPING
When planning a landscaping project,
the first step is determining the quantity of landscape materials
you will need.
How much mulch do I need?
How many teaspoons in a
tablespoon?
How many plants are required to cover an area?

This page provides some quick calculations for the number of plants
it takes to plant a certain area, as well as the amount of
landscaping mulch or stone material required to cover an area. We
have also provided details on some other
weights and measures you may require in various landscape
maintenance projects, such as calibrations for mixing pesticides.

Coverage of Topsoil
per 100 square feet
Important note: Quantities can vary due to the moisture
content and type of topsoil. Quantities below assume that one cubic
yard of topsoil weighs 2,250 pounds, and one cubic foot of topsoil
weighs 83 pounds.

Important note: Quantities can vary greatly due to
the moisture content and type of mulch used. Our "experience"
quantities relate to DLS experience with dry, doubleshredded
hardwood mulch, where 1 cubic yard covers 150 square feet at our
recommended depth of 11/2 inches.
