Surface water from last week's snowmelt has been absorbed and the golf course remains in good shape. Frigid overnight temperatures this week have created frozen ground conditions.
The freeze-thaw cycles this winter have provided a nice natural aerification. As the soil profile expands and contracts during these cycles, air-filled pore spaces are created. The increased pore spaces provide a healthier, more balanced soil profile. This, in turn, provides a better medium for the plants to grow.
