I have a brick retaining wall that is growing moss. Any suggestions for removing it? Cleansers, brushes, etc. Thanks.

  • Pressure wash could be a good solution for this. How old is the brick wall? If it is old and crumbly may not be a good solution.

    A stiff brush takes a lot of it off. A solution of ferrous ammonium sulfate sprayed on it will also help.

    Home Depot has a granular product in its garden section to rid you of moss, but the more important thing is your wall is retaining moisture causing it to grow, so u may want to find a way to release it, I hv moss growing on my walls, but I kinda like it - gives the wall character

    Wet N Forget. Google it, works great. Got mine from Costco.

    I just love seeing moss on brick, especially if it's a retaining wall or pillar or anything that isn't part of the house. I say... let it grow and let it age; just like having a patina on copper... adds to the outdoor mood.

    Thanks everyone! The wall is between my driveway and my neighbor's lawn. All the moisture comes from his front/side lawn. I want to be safe and considerate of his property. All of your input is greatly appreciated!!

    Use a pressure washer with some chlorine bleach sprayed on afterwards.

    Latoya, I too have used Wet n Forget for the past 2 years. The biggest problem is getting out the tank sprayer and getting it done! This product seems to last for the season.

    Spray with vinegar

    I'm with Ricardo. I don't understand why you would want to get rid of it.

    Bleach, let sit. Scrape off with flat bladed knife or scraper, like putty knife or spackling blade.

    moss has no roots and will not harm a brick wall

    I just finished pressure washing out 100+ year old stone wall that had beautiful moss on it and it took every bit of it off. I only used water so no chemicals were used.
