This week I have watered each day until I had standing water, I did this each day since its so dry out. I will do the same this week, and I have noticed a big positive difference. The normal watering habits I used prior to this dry spell, just wasn’t cutting it(slower growth). I would say run that sprinkler about 20-30 minutes, then take a little shovel, and dig a hole here, and there and see what you got for moisture a few inches down at least. As Crappy said, might need to water a second time which is common sense for this weather.
