Most in the Midwest will be in a heat wave starting this weekend for at least 5-6 days. Temps in the 90's, dew points in the 70's. I still have a number of Rd 3's to do yet. After tracking up a lawn with my PG (combination of stressed turf, lack of rainfall, and outbreak of asochyta leaf blight), I have become gun-shy of trying to app in borderline temps. Some of my Rd 3's I can just push back a few weeks as they are pretty clean lawns. There are a few that really should be done soon though. Question is this - is it ok to go out early AM's (say, before 10AM or so), and work a few lawns with dry fert and liquid weed control, knowing that the temps after that point will rise a fair bit beyond the general 85 degree breakpoint for stopping apps? Just to note - we were a little dry around here until today, which we got 2.5 inches of rain, so for the next few days we will not be dry.
