5.0 out of 5 stars Unbelievably effective

Pros: I've never used a herbicide before but was constantly out in my front yard pulling weeds; my grass is Zoysia so it doesn't take much for them to poke up above the surface. Three or 4 days after applying Celsius WG, they were all turning brown. Now my yard looks the best it ever has and I'm not out there constantly pulling weeds. I used it about a month ago at this point and my yard still looks great.Cons: The prep is very specific and you have to use a particular blend of Celsius WG, water and a "non-ionic surfectant." Not knowing what a "non-ionic surfectant" was, I did some research. You can buy it or you can just make it yourself with a little bit of Sprite and vinegar; you don't need much. I think it was a tablespoon of each along with a small amount of Celsius WG in a gallon sprayer.Cons: Cost; this is very expensive and in the quantity I used for an application, I'll have a number of lifetimes of usage. My yard isn't that large so I'll be willing my supply to my children along with my recipe for non-ionic surfectant.It would be good if it came in a smaller package as an option but, regardless, this stuff is absolutely amazing.

Applied about 5 days ago and Ive already seen clover wilting, crab grass is turning lighter green. Of all the products out there from my many hours of reading through forums/blogs/etc this is the stuff to get if you have sod type grass. Ive tried multiple times over the years to get the lawn looking great and resorted back to just paying someone. I think this year ive finally found a product that actually works.

This product is impressive! we had SO MANY weeds! and different kinds! within days you could see that they were dying, and in weeks they were all gone and my grass is thriving. Cannot recommend enough

4.0 out of 5 stars Expensive, but it works

Started by buying two of the small packets and applied about a month ago. In the area that I treated, the heavy infestation of dollar weed and button weed was killed off, and the centipede grass was left alive and is looking healthy. So this time I purchased the more "economical" larger container and will be treating the rest of my yard. Since celsius is so expensive, I purchased some dye indicator, too, to help with applying as precisely as possible.

I decided to quit messing around with cheap products that don’t deliver results or damages the grass. This product just stops weeds from growing and the grass continues to grow. It was pricey, but I have enough product to last 2-4 growing seasons now. It’s a good product and will knock weeds out of your warm season grass
