How long does it take for Celsius to kill doveweed in St. Augustine grace?
I applied Celsius five days ago. When should it take affect? Should I reapply?
It could take 1-4 weeks in order for the doveweed to die completely. The speed will depend on varied temperatures and will be fasted in warmer temperatures. Weed control may be reduced if application is made in the prescense of heavy dew, fog, and mist/rain or when weeds are under stress due to a drought. A second application of Celsius can be made 2-4 weeks after the first treatment. Please let u sknow if you have any additional questions.
