How to Prevent Lawn Moss

Overview

Lawn moss is a fairly common problem in most lawns. Although not dangerous for a lawn, moss can cause the lawn to become patchy and prevent new grass from growing. Wet winters in mild climates cause moss in lawns which are undernourished. Thick lawn grass that is given the ability to dry properly in the sun is generally not affected. Soil that drains poorly will cause lawn moss as well. Lawn growing conditions in general need to be maintained to prevent lawn moss.

Step 1

Take a sample of your lawn soil and send it to your local university extension office for a pH test. If necessary, add lime to your lawn to prevent further moss growth.

Step 2

Rake the lawn to remove dead grass, called thatch, from the surface of the lawn soil. This decaying waste feeds lawn moss.

Step 3

Prune trees and shrubs in the area of the lawn moss to improve light conditions and improve air circulation over the affected area. Sun and proper air circulation will help the area dry, preventing the growth of lawn moss.

Step 4

Mow the lawn regularly to encourage dense grass growth throughout the lawn and break up moss in the lawn.

Step 5

Fertilize the lawn according to the results of your pH test. Neutralizing the pH of the lawn will improve grass coverage and prevent moss.

Step 6

Aerate the lawn using a lawn aerator to improve drainage in the soil. Run the aerator in two directions to increase water circulation in the lawn.
