Best Moss Control of 2026

"I found this product to be super easy to use and was surprised by how quickly it started killing the moss in my yard. The shaker bottle makes application simple, and I saw a noticeable difference within days."

"After trying similar products that didn’t work, I was pleased that this one actually eliminated the moss. It took a few applications, but it’s so much better than letting the moss take over. I’ll definitely use this again next season!"

"The product seemed to help with our ongoing moss issue, but I did notice it left an orange-brown stain on my sidewalk that hasn’t washed away, even with all the rain here. The moss is starting to come back, so I wish it lasted longer."

"I used this moss killer on my screen porch roof to satisfy my insurance company, and it really did the trick. The moss turned brown, dried up, and was easy to remove with a hose and broom. My insurance was happy afterward, so I’m satisfied too!"

"After struggling with stubborn moss in my front yard, I finally tried this product and attached it to my hose. By day four, I noticed a dramatic difference—my lawn looks healthier and I’m relieved to have found something that truly works. I’m excited to finish treating the rest of my yard!"

"I have a VersaCourt tennis court that collects a lot of moss after rain. This spray was easy to attach and operate, and within a few days, the moss was clearly dead and brown. I was a bit hesitant about using other products on the plastic tiles, but this worked great without any issues."

"I was seriously impressed by how quickly and thoroughly this moss and algae killer worked on my lawn. After just one treatment, the moss started dying back in less than two days, and by the end of the week, it was completely gone. The application process was super simple with the hose attachment, and I love that it didn’t harm my grass at all. My yard went from patchy and moss-covered to looking lush and healthy. Highly recommend if you want an easy and effective solution!"

"The product did a great job killing off the moss on my roof—it turned brown within days, and after a week, it was dead. The hose setup was a breeze, and there was no damage or staining to my roof or gutters. Just a heads up: you’ll need to physically remove the dead moss after, as it doesn't disappear on its own. I’m planning to use it regularly because it’s so effective and affordable."

"I tried this on the moss in my yard and driveway, and while the applicator was convenient and easy to use, unfortunately, it didn’t kill any of the moss even after a week. I soaked the area thoroughly, but there was no change, which was surprising given my positive experiences with other products from this brand."

"After years of battling a hopeless, weed-ridden lawn, I tried several Jonathan Green products. This moss control worked incredibly well—moss started dying within days, and now my new grass is thriving where moss once was. Much better results than anything I've bought at big box stores."

"I had a major moss problem after living in my house for 20 years. Tried every spray out there—this was the only product that actually eliminated the moss and kept it from coming back for a long time. Just know that you’ll need to reapply occasionally."

"When I used this moss control, the moss turned black quickly, but I still had to rake it out thoroughly to prevent regrowth. Best to apply heavily in the fall, clear out the dead moss, and then overseed to get your lawn looking its best."

"Living deep in the woods by a river, moss is a constant issue for me, and even lime never really did the trick. But with this product, I noticed immediate results—the moss started to die off right away. I highly recommend buying the hose-end spray bottle and refilling it with the concentrate for the best value. It’s worked wonders on my yard and black asphalt, and it’s absolutely worth every penny."

"My lawn was overtaken by moss after the winter, and I credit this liquid product with saving a large portion of my grass. The moss turned black almost instantly after application, and my lawn began to recover quickly. I saw a drastic difference overnight and even my neighbors noticed the improvement."

"I’ve used both the liquid and granular forms to tackle heavy moss in my 3/4 acre lawn. The granular is great for large open areas, but the liquid is perfect for corners and dense moss. The moss turned black within minutes, so I knew exactly where I’d applied it. Just be careful—it can stain concrete or light clothing if you’re not cautious."

"I was worried about using this on my yellow vinyl siding after reading about fading issues, but after a careful spot test, I found no fading or damage at all. Cleaning was incredibly quick—the algae and dirt disappeared within minutes. I appreciate that I didn't need a pressure washer, just my regular garden hose. My only caution is the strong smell and the need to use more product for bigger jobs, but it's still far cheaper than hiring a pro."

"After seeing a YouTube demonstration, I decided to try this on my heavily soiled siding. I sprayed, waited a couple of minutes, and rinsed—most of the grime came off instantly. I did have to respray a few spots, but that was only because I ran out of solution. I was surprised by how thoroughly and easily it worked. This saved me the hassle and expense of hiring someone with a pressure washer."

"I'm usually skeptical about these kinds of cleaners, but after struggling to remove moss with a power washer, I gave this product a shot. It removed tough moss and stains effortlessly, even on the second story where the pressure washer couldn't reach. It saved me a lot of money compared to hiring a cleaning service. The only downside was the bottles leaking a little during shipping, but overall, I'm very happy with the results."

"I've been buying this product for years and it's always worked, especially with just one application to kill moss. However, lately, I've had to use it multiple times and it's not performing as well as it used to."

"I was initially concerned about using this on my yellow vinyl siding after reading reports of color fading, but spot testing showed no issues. I finished the whole side of my house, and the algae and dirt disappeared within minutes. I recommend spot testing first for colored siding, but for me, it worked amazingly well. You don’t need a pressure washer—just a garden hose. Still, it takes a fair amount of product, especially for larger homes, but it’s much cheaper than hiring someone to pressure wash."

"After seeing a YouTube demonstration, I tried this cleaner for the algae buildup on my vinyl siding. I sprayed it on, waited a couple of minutes, and rinsed. The results were impressive—most of the grime vanished with only one application. A single bottle covered about 20 feet by two stories, which was enough for my needs. I had dreaded needing a professional service, but I’m glad I could handle it myself so easily."

"I had previously tried power washing my siding with little success, especially for the moss on the second story. This product, however, removed the moss and stains effortlessly. I would definitely use it again and it saved me from hiring a cleaning company. The only downside was that the bottles leaked a bit during shipping, but I still had enough product to finish the job."

"I've used this product to tackle heavy moss on my clay tennis court, and it completely eliminates the problem. Much more effective than liquid alternatives—I highly recommend it."

"This did a great job controlling moss in my lawn and was simple to spread. Plus, the grass looks much greener now, likely thanks to the iron."

"I noticed very little improvement after using this, so I wouldn't suggest buying it. It just didn't deliver for me."

"I've used this product at three different homes, and it’s truly brought my garden back to life. Living in the south, moss and lichen are everywhere, but this stuff is a game-changer. I recommend it to everyone I know—it’s simply the best solution I’ve found!"

"I decided to try this on my fruit tree and crepe myrtles, even though the experts said not to worry about the moss. After applying it, the fruit tree bloomed beautifully for the first time in years, and my crepe myrtles are thriving. It’s clear now that the trees do better without the moss, and I’m totally convinced this product works—definitely worth a try."

"I was drawn to this product because it’s pet-safe and doesn’t stain, but I was disappointed with its performance. It didn’t kill much moss, and the bottle didn’t cover a large area. I usually trust Bonide products, but this one didn’t meet my expectations for moss control."
