Prime SourcePrime Source Celsius WG - 0.226 oz Easy Mix Packet-Post Emerge Weed Control

I've tried many Herbicides, this one hit the nail on the head. I've done granules, works but kills a lot more than weeds, Mesotrion, but that kills more than weeds as well and is designed for Northern lawns. I bought 1 package of Celsius, I mixed the whole package to 4 gallons of water, Blue die and some Surfactant and walla! Its been only 1 week and I have the hardest weeds I couldn't kill turning yellow and grass staying green. FINALLY a product that works on Southern lawns.I live in Orlando Florida and this is the results for this area. So for Florida this stuff works, Yes its expensive but its worth it. It actually works so pay the difference and whack some weeds!My exact mix was the whole content of package to 4 gallons of water, I went as far as package stated as to the strength advised. Then, 4tsp of blue dye and 2 tsp of Surfactant. NOTE: They recommend NO Surfactant if your spot treating. I waited one day, then the next day watered the lawn mildly just enough to wash the chemical into the lawn.Im impressed so far with only 1 week from treating.

We have some very obnoxious weeds that don't respond to standard herbicides. Researching the varieites, it appeared Celcius was probably the best choice. It worked great on the dichondra, but had difficulty with the Dalias Grass (which is almost impossible to kill unless you use round-up). One needs to be careful as it can hurt centipede and zoysia -- we did see a bit of yellowing, and stunted growth for a month or so, but the grass recovered nicely, and 4 months later shows absolutely no sign of damage. Knowing this, I did not want to spray the entire lawn and only wanted to spot kill in the few areas we had problems. Celcius is used commercially a lot, so most offerings were for much larger quanties than I'd ever use, and it is rather expensive. These small packets were a perfect choice.

Follow the directions. I used this in our yard for sandburs and on dollarweed that was overtakingthe front yard (mostly centipede and bernuda grass). About a week and a half later, the dollar weed started turning yellow and haven’t been stepping on painful stickers and the dog hasn’t been covered in them, so I think those got killed as well. About a month later, the dollar weed were all dead (where I sprayed, anyway) and the grass was not harmed. Was a bit skeptical at first as I had tried all sorts of weed killers, and it rained a few days later so I thought it would wash off. But I did add some surfactant to the mix as suggested. I’ll probably get to spraying the back yard soon.

I have St Augustine and this killed all the weeds and some of the grassy weeds without hurting my Grass.

This stuff is amazing. I’m in Zone 8A and used it with Certainty on my Bermuda lawn. This combination took care of 90-95% of the weeds I had in my lawn with no affect on the Bermuda. Now it’s manageable for spot treatments. Great stuff. As always, read the application instructions for your lawn type.

I bought to help help with some weeds in my Zeon Zoysia lawn. Very easy to use and works well. Have bought several times now and will be buying more.

Does not work on Dallas grass as claimed.

This did great killing the weeds, plus did wonders in making the grass grow back again! Awesome stuff!!!!
