Crazy weather update
Southern California, March 18, 2007. This is a follow-up graph for the weather that might have threatened the turf during aeration. Prevailing weather conditions were more or less normal for the weeks before March 11th. Look at what happened on the 11th and 12th - high temperatures and the relative humidity plummeted. Fortunately, the high temperatures did not persist and the aeration was accomplished with little stress on the grass.
