How to Prevent Moss From Growing in My Lawn


Moss is a green plant that grows without a root system and spreads through the production of spores. Moss growth in a lawn is a symptom of problems with the lawn or soil. The plant thrives in areas where there is low soil fertility, acid soil pH, compacted soil or where the lawn is wet or excessively shaded. Moss problems are solved when the overall health of the lawn is increased.

Step 1

Test the soil pH, as grass prefers to grow in soil that has a pH of 6.0 to 6.5. Apply lime to the lawn to increase the pH number. Lime will not kill the moss but creates an environment for better grass growth.

Step 2

Remove moss growth by pulling it from the ground or spraying a cryptocidal soap to kill the moss. Rake to remove dead moss and apply a 1/4-inch layer of compost to the problem area. Reseed with a grass seed recommended for the area and sun condition.

Step 3

Apply a slow-release fertilizer to the lawn in the spring to increase the soil nutrient level. Low nitrogen levels in a lawn will stimulate moss growth.

Step 4

Increase sun exposure in areas that are densely shaded, as moss thrives in cool, shaded areas. Prune trees to allow some sun exposure and plant a shade-tolerant grass in areas where tree pruning does not solve the problem.

Step 5

Eliminate areas in the lawn where water pools and does not absorb into the soil. Aerate the lawn to decrease soil compaction. Thatch the lawn to decrease the amount of dead growth at the ground level.
