How to Stop Grass Growing in Peat Moss

Peat moss is a useful landscaping tool for amending soil, creating potting mix or for mulch. Peat moss is such an effective substitute for soil that if you leave the bales in long-term storage, they can collect grass seeds. These grass seeds can sprout in the peat moss and bind it with their roots. To prevent this, you must take steps to stop grass from growing in peat moss.

• 1

  Break up the peat moss with a garden rake to cultivate the grass. Peat moss is a loose amendment that can be broken up very easily. Breaking up the peat moss will uproot grass sprouts.

• 2

  Cover the grass with newspaper. Organic gardeners regularly use newspaper as a mulch to kill grass. Newspaper will block sunlight and smother grass in the peat moss.

• 3

  Soak peat moss with water. Cover the peat moss with clear plastic. The clear plastic will heat the water inside the peat moss in a greenhouse effect and bake the grass growing in the amendment. This process is known as solarization. Solarization is a good way to kill dormant grass seeds in your peat moss as well.
