What's reasonable, in your experience, for course closures for aerification? Assume course is always closed to play on Monday, so aerification can begin then. Greens only aerification - in addition to Monday, how many more days should the course be closed?
Same question, but assume both greens and fairways aerification? We've gone from a history of getting the greens done in two days, to now, 4 or 5 days when the course is closed. I know, I know, every situation is different, and how you combine the work on fairways and greens, or not, but are there any general principles. Naturally, one wants as many play days as possible as well as a well-conditioned course. I'm not saying it is easy.
