How to Eliminate Lawn Moss Thatching


It's spring again. The trees are budding, the wildflowers are blooming and the moss is spreading. Lawn moss is a rootless plant that reproduces using spores. It thrives in lawns with acidic, moist and shady soil--especially in areas where grass is weak or completely dead. The best way to eliminate lawn moss is by creating a grass-friendly environment.

Step 1

Test the soil's pH and add the required amount of lime to raise it to between 6 and 7. Follow the recommended application rate on the manufacturer's bag, as it differs from brand to brand.

Step 2

Spray the moss with a copper-based herbicide. Moss herbicides will stain the soil, so apply it only to the moss' surface.

Step 3

Rake the moss up and place it in a garbage bag once it dies.

Step 4

Reseed the area with fresh grass seed. The grass prevents any moss from returning to the area.
