Lawn Fungus Control

First time I used this. I think my lawn became immune to the Scott’s disease ex but this worked it stop my fungus in lawn and is healthy again. Next summer I will rotate this and Scott’s

Was looking to use a different one as you are supposed to rotate and this was a great choice. It may be pricey but you do get a lot of coverage and it is a great one.

Fungus on lawns can start in damp and humid conditions. It is best to start treatment as soon as possible when you suspect it to prevent spreading. READ the description on the webpage about Prevents & Treats and what it says about damage that has already happened. It is like more of a preemergent preventive. Once a lawn gets fungus it can become a problem every year and reoccur. It has happened to our lawn and it can be pretty hard to clear up or correct damage once there so it is best to try to do preventive care-get it down ASAP if you know your lawn had problems in past years. Our lawn has had to be treated for fungus for the last three years. I didn't necessarily expect it would treat mushrooms as I didn't really see anything on the bag that stated this, it was more for different lawn/turf diseases. Lawn mushrooms are more like growths that can occur especially after a heavy rain or over-watering a lawn rather than actual lawn diseases of the grass blades. You can prevent over-watering your yard but you don't have control over heavy rainfall which can trigger mushrooms. This is where good drainage and aeration can help. Our lawn is a Kentucky Bluegrass mix, so mainly a cool season grass which does not do well in warm humid conditions. This Jonathan Green Lawn Fungus Control can be used on cool and warm season grass. It can take awhile to see progress depending on how bad your lawn is diseased, don't necessarily expect results in days or to be cleared up right away. Sometimes a 2nd application is required and sometimes depending on severity damage can persist. Make sure to actually check out what fungal turf diseases of the grass look like if uncertain to make sure you are in fact treating a fungal disease. Also, it is suggested to rotate and use different fungal products sometimes for best results. Good luck.

This product quickly eliminated the fungus. My Zoysia grass has never looked better. I will be adding to my fungicide rotation.

Purchased 4 bags of Jonathon Green Lawn fungus control Feb. 2026 to be used when warm weather arrived. I attempted application on 4-24-2. Two of the bags were great, but the other two were filled with huge lumps. Some of the lumps could be crushed with strong squeezing, but most of the lumps had to be disposed of. The bags that I did attempt to use constantly plugged the hole in my lawn tractor mounted electric spreader, Very dissatisfied. This was my 2nd. purchase, but considering the lack of quality control, I'm likely going to return to Disease Ex by Scotts.

I decided to try this after using Scotts, which made my lawn 10 times worse and another brand which really didn’t do a whole lot. My photos are exactly one week apart and only 1 application . You can clearly see the difference. Very pleased with the outcome. It is a little pricier, but definitely worth it in the long run. I was buying multiple bags of the other brands which ended up costing more money in the long run and they either made it worse or didn’t do anything. Definitely recommend this product..

After one spreading of this we saw a great improvement in killing the fungus we had in the yard and new grass growing was able to take over .. did a 2nd treatment and you can’t tell where the fungus was that killed spots of grass in the yard

Delivery was extremely fast and product was undamaged. TBD on fungicide effectiveness.
