Best Moss Control of 2025

"I have a VersaCourt Tennis court, and after spring and heavy rainfall, I noticed a lot of moss. Using a garden hose to spread the spray was simple to set up, and the built-in switch worked perfectly. It takes about three days for the moss to turn brown and die. I found it effective, but it’s a bit pricey. I was hesitant to try ferrous sulfate because the instructions warned against using it on hard surfaces."

"I used two bottles on my lawn, but unfortunately, the liverwort is still present. The initial spray did kill some of it, but not all. The second bottle didn’t improve the situation much either. I think I’ll have to look for another solution."

"I’ve been using this product on my trees to eliminate moss and other fungi. It’s easy to apply and comes in a good size, but I’ll need to buy more for the fall season to prevent the fungus from returning."

"I've used this for two years now and will continue yearly. It's much better than power washing, super easy to apply, and effective for days after the initial spray."

"I apply this on my asphalt shingles and wooden deck. It's easy to attach to the hose and sprays on easily. The product removes mold, mildew, and algae effectively. I notice immediate results, and even rain enhances its efficiency over time."

"I had previously used this product, and it takes a little while to see improvements after spraying the roof. I just started using it again, but unfortunately, the first jug fell off the nozzle, wasting some product. However, I didn't face any issues afterward and still appreciate the results, even if they take some time to appear."

“I started using several Jonathan Green lawn products to tackle my hopeless, weed-infested lawn. After applying the moss control product, the moss began to die off within days, allowing my Kentucky Bluegrass to sprout beautifully.”

“I applied this product twice, but unfortunately, it didn't work for me. The moss is still growing, and I feel like I wasted my money.”

“After using this on my mossy patches, I noticed they turned brown and died. It worked so well that I need to order a second bag!”

"I have used this product for years, and it always worked well from the big hardware stores. However, after applying it 3-4 times to the same areas, the moss is barely affected."

"Is there a post-pandemic decrease in effective chemicals? I wonder if they are cutting back on the product to save money. I would not recommend buying this!"

“I used this on my tree before work, and I could see the side I didn't treat was completely dead! I also applied it to my concrete and roof, where moss was growing. It was easy to use, and although it has a smell, it’s not overpowering. The sprayer wasn't perfect but got the job done. As a homeowner on a budget, I highly recommend this product!”

“I sprayed an area in my yard where moss was preventing grass growth. Two days later, the moss was gone, leaving only a whiteish powder. I was so impressed! However, I did experience some leaking with the sprayer, especially when it was getting low.”

“I applied this product to remove algae and moss from my roof, and it worked well. I let the rain wash it off, and I’m pleased with the results. It’s been a relief to find something effective for this issue.”

"Living in the south, I battle lichen and moss constantly! This product works wonders! It has truly revived my garden! I've used it in three homes and recommend it to everyone. The BEST product!"

"At first, I thought it didn't work well, but then I noticed the moss quickly died off. I would definitely use this again if the problem returns."

"I tried this on my Lindon tree to eliminate the moss. There was no foam or suds, which made me uncertain if it was working. After three applications, using half the bottle, most of the moss remained. It seemed like the moss removal was just due to the hose pressure. No discoloration occurred after any applications, so it might not be suitable for my needs."

"I found this product easy to use, but I definitely recommend wearing a mask while applying it. The name is a bit misleading since it doesn’t work in just 30 seconds, but I noticed improvements on my mossy driveway after two days. It looks better every day, and I didn't need to use a hose or power washer!"

"I've struggled with moss on my patio for a while and decided to give this product a try. I was pleased to find it didn’t discolor my stonework like other moss killers I’ve used. It does require a 5:1 dilution and multiple applications over several days, but it eventually killed the moss without any issues. Just a heads-up, this product is still a chemical, so I kept children and pets away while using it."

"While this product works well on green plant matter, I was disappointed that it didn’t have any effect on the black plant matter staining my siding. I saw some improvement in the green mold after a day, but the black soiling was untouched even after a week. I probably wouldn’t buy it again since it didn’t meet all my cleaning needs."

"I watched some YouTube reviews, and one mentioned that the concentrate works better on roofs than the hose-end sprayer. So, we got both! I mixed up a five-gallon bucket with more concentrate and applied it to the moss and scales on our porch roof. A few weeks later, I can see that the moss is gone and the product is working as intended. We plan to use the concentrate again for the next treatment."

"A friend recommended this product, and I was amazed at how quickly it removed black and green mold from my outdoor statues and brick. What’s great is that it continues to work even after it rains! It’s also incredibly easy to use."

"I've used this product for several years, and it definitely lives up to its claims. The results aren't immediate; you spray it on the algae and mildew, and over a couple of days, it starts turning brown and eventually disappears. I use it regularly on my shingled roof and brick walls under tree cover, and I highly recommend it!"

“Before I discovered this moss, I was buying sphagnum from a local hardware store for my first orchid. This product is far superior, with no bugs or mold. Although it seemed like a small chunk, it expands significantly when hydrated. I’ll definitely be purchasing more in the future.”

“I absolutely love this moss! It regenerates into live moss, making it perfect for my collection of pinguiculas and terrariums. For the best results, I recommend rehydrating it with distilled water and providing bright light. The growth is impressive, and I’ve found it works better than other brands for my propagation projects.”

“This is the best sphagnum moss I’ve ever used! It hardly has any twigs or sharp bits, just pure, quality moss. I switched from peat moss to this product and noticed a significant reduction in algae growth. The initial package may look small, but it expands greatly in water. I’ll definitely be buying this again.”

"I was disappointed when I received only one piece instead of the two pieces advertised."

"The price was misleading; I expected more for my money."
