Products to Remove Moss

Rake

• Moss grows very shallow roots. Whether it's growing in your lawn or on a hard surface, you can control moderate invasions of moss by brushing the affected surface vigorously with a rake. You also often use a rake for preliminary moss removal before treating the surface with other moss removal products.

Power Washer

• Power washers are one of the best ways to remove moss that's growing on shrubs and trees, according to Oregon State University. For optimal results, the university suggests using a power washer during the winter when the tree or shrub is dormant.

Sulfates

• Virginia Tech University suggests using iron sulfate granules or sprays for treating moss invasions in a lawn. Such products come preformulated or premixed and are designed to kill moss and prevent its regrowth without harming your grass. For the best results, pick a product that lists one of the following iron compounds as its active ingredient: copper sulfate, ferrous sulfate -- which is sometimes listed simply as iron sulfate -- or ferrous ammonium sulfate. Because iron creates a red stain, restrict such product usage to your lawn; keep it off landscape furniture or pathways.

Lime

• When applied to hard surfaces, lime adjusts surface pH and makes the area inhospitable for moss. And unlike iron-based sulfate products, lime products don't stain. You can buy hydrated lime or ground limestone granules in most garden stores or nurseries. For effective moss control, Virginia Tech recommends spreading lime at a rate of 1 pound for every 500 square feet, or 50 pounds of ground limestone for every 500 square feet.
