How to Kill Moss Permanently

Reduce the amount of shade around your home and garden. Moss will thrive in shade, so you need to make sure enough sunlight gets through to your home. Use pruners and a chainsaw to thin the branches of the trees surrounding your yard. Remove any unwanted trees that block too much sunlight.

Improve the drainage of your lawn. Use a tiller to till the soil in areas of heavy moss growth. Set the blade depth to medium, and till the areas where you see lots of moss. The improved drainage will stop moss from thriving in the area.

Spray a moss herbicide directly onto moss-covered areas. Use a rake to rake out the dead moss after it begins to brown.

Seed and fertilize your lawn each spring. A healthy, robust lawn will keep the moss from growing amongst the grass. Use 2 to 4 pounds of nitrogen-based fertilizer per 1,000 square feet.

Refrain from cutting your lawn too short. Set your lawnmower blade height to between two and three inches. Cutting your grass too short weakens the grass blades, and will allow moss to grow more easily.

Avoid watering your lawn too frequently. Moss grows best in moist conditions, so refrain from watering your yard any more than you have to. When you do water, water for longer periods of time to let the moisture soak deeply into the soil, but do not water often.
