I snapped this picture the other morning, as it is very representative of challenges that we are facing on the fairways. You can see a sprinkler head on a slope and a distinct pattern below it, where the water tends to bleed out during operation. That area is almost 100% poa annua and by no coincidence, on the verge of death. The poa is suffering from salt stress and disease from the high salt content of our irrigation water. The surrounding healthy turf is bermudagrass, which is much more tolerant of high salts.
