Tee aerification took place last week on Greywalls.  The process was broken into two days and was accomplished flawlessly.  The cores were vertically mowed and blown off before mowing.  We followed that up with an organic Sanctuary fertilizer application.  The 1.2" rain the next day was fantastic for us as it helped get water into the hole filled profile and reduce the localized dry spots (LDS) on the tees.
