We have come through a period of unseasonably hot, and humid weather. This type of weather is hardest on our weakest grasses. Hand watering to cool the grass in the afternoons is a very important tool we use to help the grass survive. The good news is that stressing out the weaker grasses allows the stronger grasses to fill in. The forecast is for cooler, wetter weather in the near future so the pressure should be off for a little while.
