Stress on some zoysia tees

The core aeration of our zoysia tees last week placed some stress to our zoysia tees, especially since it stayed in the 100 degree range.  Opening the tee canopy and  dragging the tees does add stress and will dry out the surfaces which did occur on isolated tees.  Our tees have good irrigation coverage but stress will show up on some tees that do not have adequate water coverage.  A few of the forward red tees only receive water from rough and our fairway coverage heads which at times are not spaced properly to get the proper water to relieve stress.  We've increased the watering totals over the last few days and the tees are beginning to show some relief from the stress they have experienced.  Cooler weather and rain will get the tees back to normal in the next few days.

Our cool season tees continue to react negatively to the hot and dry weather of the last few weeks.  They should respond in a positive way to changes in weather as well.
