Why Put Peat Moss on Grass Lawn in the Yard?

Peat moss can be a valuable amendment for lawns that are not doing well because of compact or heavy soils. Once incorporated, peat moss helps to separate soil particles, resulting in better air movement and increased biological activity.
  1. Retaining Moisture

    • Peat moss acts like thousands of tiny sponges in a lawn.

      If you lawn is prone to drying out in spots, a layer of peat moss as a top dressing can help to retain moisture. Peat moss acts like a sponge, imbibing water. Lawn grass that is in contact with the moistened peat moss can absorb some of that stored moisture.

    Improving Lawn Drainage

    • The incorporation of peat moss into a lawn can improve aeration.

      If your lawn is in a heavy soil, the addition organic matter can help to improve it. A layer of peat moss thinly spread over an existing lawn will help to improve the soil structure, resulting in a healthier lawn.

    Seeding Lawns

    • Grass seed needs an environment withouth competition to germinate.

      Peat moss should not be used when establishing new lawns. The peat moss will out-compete new seed for moisture. Unlike straw, peat moss will not decompose, and will create a barrier through which the seed may not be able break.
