Lilly Miller Moss Out for Lawns kills moss in lawns so grass can grow into a thick lush turf. Moss grows on the soil surface in lawns where it competes with the turf, causing the grass to thin out and creating an excessive build-up of thatch. Shaded or poorly drained acidic areas encourage moss growth. Apply Moss Out for Lawns to these areas when the moss is actively growing. Moss Out for Lawns gallons covers 2,000 sq. ft. After applying you will see the moss turning black within hours.

  • Kills lawn moss quickly, works in hours
  • Economical concentrate covers 2,000 sq. ft.
  • Liquid iron gives superior results
  • Apply with a sprinkling can or hose-end sprayer

Rated 4.6 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by Very quick work! Our yard is very large and very wet and, therefore, very very mossy. Lilly Miller Moss Out and Fertilizer product killed the moss very quickly. Once we raked out the moss and reseeded, the lawn looks 100% better. I've used other products that took almost a week to kill the moss and then had to second coat it to finish the job. With this Lilly Miller Moss Out and Fertilizer, I was able to reseed almost right away. June 26, 2014
Rated 5.0 out of 5.0 by Woked well and fast. I used it a little stronger than the prescribed mix. March 25, 2015
Rated 5.0 out of 5.0 by Great product This year I had moss on lava rocks in my garden due to wet weather and this product killed it in hours. September 15, 2014
Rated 5.0 out of 5.0 by Moss Out Works This stuff is great. Best when applied when the moss is starting to grow and the ground is just a bit damp. Only drawback is the available sprayers can not be adjusted to specifically deliver the recommended application amount. I wish Lilly Miller would reformulate the product so you can use the available sprayers. I got around the problem by purchasing one of Lilly Millers hose attached spray bottles and reusing it.

Rated 4.0 out of 5.0 by Works as advertised -- moss turns black in MINUTES Moss Out works as advertised -- the moss turned black within 10 MINUTES of spraying. I could see it change as I was spraying a nearby area. A week later the treated moss was still black. I have some very thick moss in a shaded area, and thus some of the underlying was a bit green in spots; however, ever there most of it was black, brown, or yellow, and pulled up easily with a hand-held garden fork tool. The instructions encourage one to pull up thick moss ahead of time, but definitely afterwards. I still have plenty of Moss Out left (I bought 5 gallons), so plan to retreat that shady area once I finish pulling out most of the dead thick moss. The only con is the Moss Out bottle with the attached sprayer is not really designed for multiple uses, and started to pop out at the neck after going through several gallons. August 10, 2014
Rated 4.0 out of 5.0 by Does what it says: KILLS MOSS I've used Moss Out for lawns (and it's sister, for roofs and pavement) a few times now. It works very well. You can see brown/blackened moss within minutes, BUT let it do it's thing for 5-8 hours. It this point you really have two options...well three. Number three is have your moss grow back. The other two are: 1: RAKE YOUR LAWN with a metal-tined rake. Get a beer or two and sweat it out. You have to do this. if you don't it will grow back because you haven't actually killed all of the moss; only the top layer. 2: RE-APPLY once to twice a year (with a beer or two). Hey...raking out moss is tough, so if you don't have thick spots, you can retreat every spring and fall... Healthy, thick lawns inhibit competitors, including moss and weeds, but we're not all Hank Hill, so, as far as moss goes, Moss Out does the job! September 12, 2013
Rated 4.0 out of 5.0 by This product works as well as any for killing Moss I followed the label directions for hose end spraying, and treated my entire yard with my Ortho sprayer. Upon initial contact, the moss turned a blackened color. Withing 2-3 days, most of the moss was black. Unfortunately, some of the "killed" moss is returning, and I will need to make a 2nd application. I did not scrap the moss as directed, so that may have aided the resurgence. I have used this product before, and it is the best you can buy, but there aren't too many products that kill moss. I purchased the gallon size because the hose end quart size only treats about 900 square feet for about 12 bucks...VERY expensive. March 5, 2013
Rated 5.0 out of 5.0 by Simply put Moss Out works well. I purchased 10 gallons of it. My yard had bits of moss throughout, and a few places of heavy growth. When moss is found in lawns, it’s an indication that conditions are not favorable for growing grass and the moss is simply filling in the spaces where the grass is not growing well. To get rid of moss, there are several conditions that may be encouraging the moss to grow including: too much shade, acidic soil, poor drainage/wet soils, compacted soil, and low soil fertility. My main problem is acidic soil, so last fall I applied lime to reduce it. I plan on a spring application also. In January, I used my Orthro hose end sprayer at a rate of 3oz per gallon. I spayed every inch of my lawn; 5 gallons worth. After spraying, I saw little black spots (dead moss) throughout my entire yard. As stated by others, the moss is coming back. This past week, I resprayed my entire yard, and still saw little black spots throughout, but not nearly as bad as after the first application. I'm thinking I will need to continue an annual application to insure it stays away. April 7, 2013
