Moss is a type of ground plant common in shaded, moist environments. Sidewalks that offer such an environment may quickly become overgrown, creating a health hazard and risk because of the moss plants' uneven surface and slippery texture. Kill all moss growth on a sidewalk with concrete-friendly techniques to restore your sidewalk's appearance.
Things You'll Need
- Pressure washer
- Laundry detergent
- Moss herbicide
- Moss spray
Use a pressure washer to clean the sidewalk. This option is best for those who wish to avoid the use of herbicides and chemicals. The washer will completely remove all moss growth while also removing dirt, debris and light surface stains. Collect the dislodged moss with a rake. Place in a pile in the sun to dry out, effectively killing the moss plants. Discard the moss, or add it to your compost pile.
Sprinkle a light layer of standard powder laundry detergent on the moss. Typically, half a cup of powder for every square foot of moss is sufficient. This is the best option for those wanting a budget-friendly technique using household ingredients. The detergent will kill the moss within 24 hours. Hose down the sidewalk with water thoroughly after application; the detergent may leave the sidewalk slippery hazardous to walk on.
Apply a commercial moss-targeting herbicide. This option is best for those experiencing heavy moss growth and wanting a rapid solution. Example products include Lilly Miller Moss Out! Most commercial moss herbicides will work efficiently on sidewalks. Avoid moss products formulated with iron sulphate, which may stain concrete sidewalk surfaces.
Spray the moss growth with a potassium salt spray. This is best for small moss growth spots and not widespread sidewalk coverage. Example products include Bayer's 2-in-1 Moss & Algae Killer and Safer Brand Moss Killer & Surface Cleaner. Rinsing is not required.
