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 34 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 3.0 out of 5.0 by Decent purchase. Description says use with sprinkling can which I interpreted for whatever reason to mean it was a dry mix, it is a liquid and needs to be sprayed with a pressurized sprayer. I don't own a sprayer tool that I could use with this unfortunately. October 10, 2015
Rated 5.0 out of 5.0 by Works Great for NW Lawns This is one product that actually kills the moss in lawns - a habitual issue here in the Great NW. I mix it up stronger than recommended just because of the tenacity of the moss up here - but it kills in minutes, moss turns black as you watch and the grass becomes noticably greener in days. I mow the grass close to enable the product to get to the moss and then use a backpack sprayer to apply. I use a power rack in the spring a couple of weeks after applying Moss Out to removoe the dead moss (dethatching best when dry in peak growing season to minimize grass being pulled out and allow grass to quickly grow back as some grass will be removed during process). Mosss Out anytime great to keep moss in check - recommend also applying in fall to minize moss growth during winter months. September 22, 2015
Rated 5.0 out of 5.0 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 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 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 5.0 out of 5.0 by Best Moss Killer One cup for three gallons of water. Use when Grass is dry, turns Moss from Green to Deep Umber Color. Easy to see if you missed any spots. Moss was beginning to infest my entire backyard. April 7, 2015
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
