You will never be able to calculate square feet precisely with scalloped or curved edges; however you can get very close. Always round up to insure you can cover an uneven grade. Remember that mature plant material can be accounted for using a percentage.
Example: I have 1000 square feet of landscaping but my plants cover 10%. Therefore, I only need 900 square feet of mulch.
Curved beds can be divided into zones; whether they be circular or rectangular.
Here we are going to "cut off" an outlying area and use it to fill in an open area helping us to create geometric shapes.
Simply take the cut away area and overlay it onto an open area. The goal is to get close and to round up.
Once you know your square footage you can use this handy calculator to find out how much rubber mulch your project needs.
