About Moss
A mossy lawn doesn't kill the grass but conditions that encourage its growth can. Moss is a symptom of an environment that isn't right for turfgrass, so simply removing it only provides a temporary solution. Improving the conditions so they favor the growth of grass is a more effective method of getting rid of moss.
Acidic or Infertile Soil
Use a soil tester to determine if it's suited to your grass. Soil that's too acidic (has a low pH level) will hamper the growth of grass. Moss, on the other hand, does well in acidic soil. In general, turfgrass needs a pH level between 6.0 and 7.0.
Poor Soil Conditions
Soil compaction and excessive thatch make it easier for moss to encroach upon your lawn. These conditions restrict the movement of oxygen, water and nutrients to grass roots and contribute to poor drainage. Aerate and dethatch your lawn as necessary; dethatching will also remove moss that's already established.
Excessive Shade
Excessively shady areas benefit moss more than grass. You can prune trees and shrubs to allow more sunlight to reach the lawn. See How to Prune Trees and Shrubs for instructions. Another option is to establish shade-tolerant grass varieties like fine fescue, St. Augustine or rough bluegrass.
Too Much or Too Little Water
The wrong amount of water will encourage moss growth and discourage the growth of grass. You should water your lawn only when necessary to supplement rainfall.
Other Lawn Stresses
Lawns that are injured from other stresses will also be susceptible to moss growth. Insects, disease, excessive foot traffic and damage from pets make it difficult for turfgrass to grow. Moss can also begin filling in bare spots in your yard. You can read Troubleshoot Lawn Damage and Diseases to learn to identify and treat these conditions.
