When applying Drive XLR8 Herbicide Crabgrass Killer you want to make sure the temp is not below 55 degrees and not above 80 degress. You can try applying early in the morning or later in the evening when the temps could be below that for better results. Weeds that are heat stressed during the day with not absorb the product well so you would not get good results.
