Moss is a rootless species of plant that reproduces by the spreading of spores or by breaking apart and multiplying into new organisms. Moss is a plant that makes good use of moist areas that are poorly draining, and will quickly attack a lawn that is unhealthy. Moss also likes acidic soil conditions and will grow in a soil pH that is unacceptable for other plants. Eco-friendly management requires good cultivation practices as opposed to chemical control.
Perform a pH test according to the instructions on the packaging to determine whether the soil is acidic. Acidic soil requires an application of lime unless the soil pH is between 6.0 to 6.8, according to the Maryland Cooperative Extension.
Rake areas with moss aggressively to break the moss apart and solve the problem short term, says Montana State University.
Aerate the soil in areas that are compacted or not draining properly using a core aeration tool, either hand-held or powered. Aeration is the removal of dirt plugs from the soil to increase drainage and air circulation.
Apply ground limestone to acidic soil at a rate of 75 to 100 lbs. per 1,000 square feet and hydrated lime at a rate of 2 to 3 lbs. per 1,000 square feet.
Prune trees and shrubs that cast shade on a lawn to increase sun coverage of mossy areas. Moss will dry out in intense sunlight.
Fertilize the lawn using 1 lb. of nitrogen per 1,000 square feet three times a year--in spring, late summer and the end of the growing season--to grow a lush turf that inhibits moss.
