How to Remove Lawn Moss


There are 1,000 species of moss around the world, says the Virginia Cooperative Extension. Lacking roots, seeds and typically shaped leaves, moss produces sexually or asexually when wet, and spreads rapidly. Regular mowing practice, and even low mowing, is not likely to remove moss from the lawn. Amending acidic soil, improving soil drainage or sun coverage and aerating compacted soil will help remove moss from a lawn.

Step 1

Test the soil of your lawn to see whether it is acidic, suggests the Virginia Cooperative Extension. Soil pH tests are available from garden centers. Samples of your soil sent to a university extension center soil testing lab will reveal your soil pH. A reading under 7.0 means you have acidic soil. Add lime to the soil to lower acidity at a rate of 75 to 100 lbs. per 1,000 square feet suggests the Clemson Cooperative Extension.

Step 2

Fertilize the lawn to improve grass coverage, suggests the Oregon State University. A complete lawn fertilizer with a 2:1:1 ratio applied at 1 lb. per 1,000 square feet two to three times a growing season will improve grass coverage.

Step 3

Aerate your lawn using a core aeration machine to relieve compaction in the lawn and improve soil drainage, says Clemson Cooperative Extension. Core aeration removes plugs of soil from the lawn, which relives compaction and eats away thatch that may cover the lawn and prevent grass from growing. Run the core aerator in both directions of the lawn for best coverage. Rake the plugs to break apart the dirt and cover thatch.

Step 4

Cut trees or shrubs that block sunlight from reaching moss-covered areas of the lawn to reduce water retention and improve air circulation to the area.

Step 5

Remove moss from the lawn by raking mossy areas to break apart the plant, suggests the Clemson Cooperative Extension.
