i'm impatiantly waiting for the frost to burn off my bermuda so i can start spraying my preemerge. My problem here in oklahoma is that the winds gust daily this time of the year. Looking out my shop door right now and it is calm but frost is on the ground. I know by the time the frost burns off the winds will be gusting.
My question is would the pre emerge have any negative effect if i spray on top of the frost?
