Peat Moss Coverage Calculator Formula

The simple formula used to measure the correct amount of peat moss youll need in any area or space is

Amount of Peat moss (cubic feet) = [Length (feet) x Width (feet) x Depth (inches)] / 12.

Using this formula, all you need to do is:

  1. Measure the length in feet (if you have any other measurement, use it. But convert the value you have to feet) of the space you want to cover with peat moss.
  2. Do the same for the width of the garden portion
  3. Determine how deep in inches you want the peat moss to be.
  4. Input these numbers for length, width and depth of peat moss needed into the formula and calculate the amount of peat moss required in cubic feet.

How do I calculate how much peat moss I need for top dressing?

Let’s use this example to calculate how much peat moss coverage youll need for a garden of length 15 ft and Width 10 ft. with a peat moss depth of 2 inches. The same result you get should be the same as what our Peat moss calculator gives.

This will be;

Amount of Peat moss needed (cubic feet) = [ (15 x 10 x 2) / 12] = 25 cubic feet

So, 25 Cubic ft. of Peat moss is what will be required to cover a 150 square feet garden at a depth of 2 inches.

How much peat moss do I need for 2000 square feet?

You need approximately 333.33 cubic feet of peat moss to cover an area of 2000 square feet with a depth of 2 inches.

To calculate the amount of peat moss you need for an area of 2000 square feet, you can use the provided formula:

Amount of Peat moss (cubic feet) = [Area (square feet) x Depth (inches)] / 12

Let’s assume a desired depth of 2 inches for the peat moss:

Plug these values into the formula:

Amount of Peat moss (cubic feet) = [2000 square feet x 2 inches] / 12

Amount of Peat moss (cubic feet) ≈ 333.33 cubic feet

Is peat moss good for sod?

Peat moss is good for sod

  • Add the Peat Moss: Spread a layer of peat moss evenly over the prepared soil. Mix it into the soil to a depth of a few inches using a rake or a mechanical tiller. The goal is to blend the peat moss thoroughly with the existing soil.
  • Lay Sod: Lay the sod over the prepared and amended soil. Press the sod down gently to ensure good contact with the soil beneath.
  • Water Thoroughly: After laying the sod, water it thoroughly to help settle the roots and eliminate air pockets. Adequate watering is crucial during the initial establishment period.
