With summer right around the corner, I hope everyone has their irrigation systems up to speed. Remember for fescue, it is much better to water deeply and less frequent. For now I would consider watering heavily every third day (assuming no rain) until we are consistently 90 degrees or better then go every other at a little lighter rate. Also the time of day you water is extremely important. Early in the morning is by far the best, before the dew dries. If you water in the evenings or afternoons you will lose more water to evaporation and have a much better chance for disease due to the longer period of time you grass stays wet.
