Syringing and handwatering greens are methods we use to maintain plant health through hot weather. Syringing crews are deployed to monitor each green during the hottest part of the afternoon, and ensure that greens do not become heat stressed. Trained crew members apply a light mist of water which cools the surface for a short time. This misting can cool the surface by 10-15 degrees, but is a temporary condition usually lasting 15-20 minutes, and often must be repeated several times during a hot afternoon. We appreciate your patience when crews are syringing during your round, and ask that you give them the right of way while they quickly syringe and maintain the health of your golf course.
