1. With a measuring tape, measure how many feet long the bed is. Then measure how many feet wide. Multiply these two figures. The total is the square foot area of that landscape bed.
2. Decide how thick you want your mulch to be (2” is average). For new landscape beds, 4” of mulch is recommended. If you are just top dressing a previously mulched bed, you may wish to use as little as 1” of mulch. Using the conversion chart below or Mulch Calculator to the right, you can figure how many cubic yards or bags of mulch, soil or gravel to order.
