The heat is back and the maintenance staff is back on handwatering greens. It is called syringing and is done to keep the greens cool during the hottest part of the day. Each green may need to be handwatered several times a day depending on weather conditions such as wind, humidity and temperature. Syringing is a job that takes great skill and considerable training. Each person must be careful to only apply just enough water to survive until the irrigation can run that night. Overwatering can lead to excessively soft and slow playing conditions, disease, and scalping injury from the mowers.
