Ruined our Patio
I bought MossEx granules because of the high recommendation and positive reviews. I applied the product as instructed, let it sit for two days and then hosed off the dead moss. Unfortunately, the pavers AND the concrete slab next to the sunroom changed colors. We are now in the process of paying to have the patio replaced. No reference on the website for Scott's stated not to use on concrete or pavers. Afterwards, my wife found in small print on the bag that it could stain. This should have been in large letters and on the website!!! I have used Scott's products for years and years but now I will have to rethink my product choices. I have included pictures, including the receipt.

We're sorry to read about your disappointment with Scotts MossEx and appreciate your feedback. This product contains iron, which can cause staining. The label states to brush particles from cement, stone, clothing and shoes to prevent staining. If you have noticed red/orange marks on a hard surface or clothing, the quicker the stain removal process is started, the more effective the process will be. Sunlight and water will help to fade the iron stains on outdoor surfaces, but will not completely remove them. While not endorsed or guaranteed by Scotts, the following products have been shown to work on regular concrete and are registered for this use. Before using any commercial cleaning products, such as those listed below, to remove stains test the product on a small area to see if the product will fade or damage the stained surface. Most stain removal products work best with two applications. Be sure to follow the label directions. -Singerman Laboratories Concrete Rust Remover (on-line at theruststore.com, fluidenvironmental.com) -Goof Off Rust Stain Remove -Super Iron Out -Techniseal Rust Remover We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 888-270-3714 if we can further assist.
    Didn't work in the summer
    We applied this the first week of July (a little over a month ago). There is no visible change in the moss. We followed the directions on the package. From these reviews, I've learned that the air temperature is important. But, there is nothing about air temperature in the instructions. :-( Guess we wasted our time and money. Haven't decided if we'll try when it gets cooler or not.

    We're sorry to read about your disappointment with Scotts MossEx Easy-to-use Shaker Jug and appreciate your feedback. We will share your feedback with the approipriate department. It can take up to 2 weeks for the product to be effective. If the moss is not actively growing, either due to improper time of year or temperatures being too high, the product will not work. if there is a heavy rain (1"+) within 2 days of application, the product may have been washed off. If the lawn was dry, the product will not stick to the moss or grass blades. The more moss that is exposed, the better the coverage. so mow the lawn before applying. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 888-270-3714 if we can further assist.
      What the bag doesn't tell you.
      This product will kill moss, however you need to apply often and continuously for about a year (depending on how sever the problem) and then add lime to "sweeten" (less acidic) your soil to make it unfavorable for moss to live. After the moss turns black get it out of your yard...use a thatching rake to pull it all up and then re-seed the grass in the bare spots that it left. This is what the bag doesn't tell you.

        MossEX Disappointment
        After 2 applications it still isn't killing the moss that was thick. It did kill the lighter areas but not the dense areas

        We're sorry to read about your disappointment with Scotts MossEx and appreciate your feedback.

        This can happen if the product is applied at the wrong time (ie: moss was not actively growing) or the temperatures were too hot for the product to work. There are two application rates on the package. A regular rate and a heavy rate that should be used for heavy infestations. We recommend applying to damp foliage in order for the product to stick to the moss or grass blades. The more moss that is exposed the better the coverage.

        Disappointed
        I applied Moss Ex to my yard on March 6th hoping to kill the large amount of moss that grew over the winter. I have been watching closely to find results, however, as of this post, my moss problem is still green. I applied per instructions using my Scott’s spreader in the prescribed setting. I am extremely dissatisfied and disappointed with this product.

        We are sorry that you are disappointed with your purchase of Scotts MossEX. There are two application rates on the package. A regular rate and a heavy rate that should be used for heavy infestations. If there was a heavy rain (exceeding 1" of rainfall) within 1 to 2 days of the application it could have been washed away. It can take up to 2 weeks for complete control of the moss. We want you to be confident in our products; therefore, we offer a product guarantee.

          There is no moss in my yard.. anywhere.
          [This review was collected as part of a promotion.] I live in an area where this product is basically useless because moss doesn’t grow out here. However I saw on the bag where some other customers had put it and decided to try it in those areas. In spring we get a small amount of moss on the sides of rocks but not much to have to “ manage”. This worked excellent on those small areas and I imagine if you had moss in your grass this would work quite well to remove it.

            Although it has a guaranteed it did not live up to it. I put the Scott EX down about three weeks ago using a Scott’s broadcast spreader on a heavy rate 2-3/4. Three bags covered my upper yard.

            My back yard has had moss growing in it for years. I have tried several things to get rid of it including using a de-thatching blade on my mower to scrub the lawn. Recently I saw Scotts MossEX advertised somewhere and decided I would give it a try. I used my Scotts broadcast spreader set to 2.75 and applied to the entire shaded back yard. Within a day a good portion of the moss had turned black as advertised, however, there were some areas still a green as ever. After a second application a little more turned black but there was still areas of green moss. I am on my second bag now and still have green moss in some areas of my back yard.

              ease of use
              [This review was collected as part of a promotion.] the moss ex was quite easy to apply. seems to have given the lawn the ability to breathe. worked wonderfully in the hand spreader to apply within fifteen minutes. the moss ex is a groovy comlpiment with scotts fertilizers.

                I like this stuff!`
                [This review was collected as part of a promotion.] I had been trying to get help putting a granular product on my garden shed composition roof, when this came along. I'm sold! I didn't need any help to use it, it won't stain anything (like the granular stuff does), and it really worked. The moss went from green to brown in 48 hours.

                  This product works really well -- it kills the moss quickly and completely, and it's very easy to apply. I have spot applied it to both areas of my lawn and areas of my roof, and in both cases it worked great! That said, a few thoughts: - Like with any lawn product, consider what is causing the problem -- and, treat the cause, not just the problem. For example, if your soil is acidic (which promotes moss growth), treat it with lime, fireplace ash, etc., to neutralize it; if it's too shady, is there a way for more light to reach the ground? - If you kill the moss, but don't address the cause, you may make a new problem. For example, the first time I used this product to kill moss under one of my maple trees, the moss died quickly, but then I was left with a muddy mess and erosion. Don't do what I did! :-)

                  How well it removes the moss from all the surfaces I applied it too. Yes it does meet my expectations which is why I buy it when needed.
