How to Kill Lawn Moss


Lawn moss can quickly creep into and take over any garden space, draining resources and soil nutrients needed for nearby flowers and plants to grow and thrive. Getting rid of lawn moss is a time consuming project that involves a combination of hand-removing and use of liquid moss-killer (available at home and garden centers nationwide). Eliminating lawn moss from your lawn and garden will take some time, but the process is simple and does not require specialized gardening skills.

Step 1

Hand-pull the moss from the areas where you wish to eliminate moss growth. Place the moss into a plastic trash bag or compost bin.

Step 2

Continue to hand-pull as much of the moss as you are able, as this will help eliminate the moss from your garden more quickly.

Step 3

Fill an empty, clean spray bottle with a solution of 1 cup water and 1/2 cup moss killing product. Moss killer is readily available at any lawn and garden center.

Step 4

From a distance of 6 to 8 inches, spray the areas that have been infected by moss in your lawn. Be sure to saturate the areas with the highest concentration of moss, as this will help ensure that the moss will not continue to grow.

Step 5

Allow to dry, do not rinse off. Check the areas where you have sprayed in 72 hours to determine whether any new moss growth has occurred. Repeat spray if necessary until moss is completely eliminated from your lawn.

Tips and Warnings

  • Wear a plastic lawn mask if you are highly sensitive to chemicals, as prolonged exposure to moss killer can cause an allergic reaction in certain individuals.
