How to Mix Peat Moss and Top Soil


Peat moss is organic matter that contains decomposed plants--often sphagnum moss. Adding peat moss to the existing topsoil in a growing area will amend the soil and make it a higher quality soil. Peat moss is acidic, so adding peat moss will help to increase the acidic level of topsoil. Adding peat moss will also improve the soil drainage in a growing area.

Step 1

Till the growing area to work the topsoil and break up the large chunks of soil. Set the tiller to till the soil to a depth of at least 4 inches.

Step 2

Add a 1-inch layer of peat moss for every 4 inches of topsoil you have tilled. If you tilled only 4 inches of topsoil, add 1 inch of peat moss. If you tilled down to a depth of 8 inches, add 2 inches of peat moss. Spread the peat moss evenly over the entire surface of the soil.

Step 3

Till the soil to incorporate the peat moss. Work the tiller over the entire growing area until the peat moss is fully incorporated.

Step 4

Rake the surface of the soil smooth.

Tips and Warnings

  • Do not leave the peat moss on the surface of the soil. Use peat moss only as a soil amendment or risk burning your plants.
