I'm a little late posting this, but greens were aerated the first week of November using a 1/4" tine. This is the first time we have done this small of a tine in the winter. We are hoping that we can increase some play over the winter as this size tine doesn't affect ball roll. Greens were topdressed as well using a damp medium sand. Come march we will either use a graden verticuter on greens or aerate using the same size tine.
