At the end of each season - early November - our maintenance practices shift to "winter protection". Now is the time to give the turf a rest and prepare it for the hardships of winter. Fertility and cultural programs are adjusted, changing from a strictly "play focused" philosophy to a "plant health" centered regime.
Part of that program is to aerify greens deeply: Deep Tine Aerification. We use a solid tine that penetrates to a depth of 8-10 inches, loosening the subsurface and providing channels for melting snow to evacuate the surface. Melting snow that turns to ice is our number one concern for turf loss on the South greens, more of a concern than any risk the turf faces in the summer. Avoiding turf loss in the winter is far more complicated than during the summer months.
