Greens speed is probably the most talked about, most volatile and most difficult issue to address in the golf maintenance industry. For some a green cannot be fast enough and for a few greens are always a little too quick. As a superintendent I am in the position of trying to find a common ground among all the members and at the same time maintaining the health and appearance of the most important area on the course. I am a fairly decent player and I do like fast greens. My definition of fast being subjective. What I also like are greens that roll true with very little or no bumpiness and "waggle" (subtle side to side movement).
Achieving the above is not just a simple matter of "shaving the greens down", a phrase I cannot stand. It involves aeration, topdressing, verticutting, brushing, fertilizing, irrigation, mowing heights, reel and bedknife design and rolling. I won't go into the details but firm greens tend to be faster and "soft greens" tend to be slower. Of course something most golfers overlook is the design of a green. Sloping greens give the perception of being faster. Flatter greens are deemed slower when one compares our greens to lets say Blackhawk's. In fact our Stimpmeter readings are very similar to theirs (news flash: superintendents communicate with each other all the time). Unfair yes, but perception becomes reality in our world.
What I need to strive for are healthy, consistent and fair greens at our course. I'm getting a little off topic but I just want to stress how many factors can affect greens speed on a day to day basis. In addition to all of our maintenance factors the weather can cause speed changes as well. Case in point. We had the greens rolling true and very fast (by USGA standards) on the weekend. Too fast for regular play, great for tournament play. The fast speeds being attainable in the future by altering our maintenance practices. We didn't roll on the following Monday (you cannot roll everyday) and they slowed down slightly. We planned to brush, cut and roll on Tuesday but heavy rains arrived and so the greens were not touched until today (Wednesday). We could only cut them as they were too soft to brush and roll without potentially causing damage. Are the greens even slower than Monday? Yes. They went from 11.5 to 9.5. Exactly what I expected.
For the remainder of the summer and part of September we will strive to maintain the greens between 10 and 11. The Club Championship and The Member Guest will see speeds similar to The Martell, all conditions being equal.
I encourage everyone to visit the USGA Greens Section (Google it) and read up on the history and the proper use of the Stimpmeter (and what in fact a stimp number means). You will also see the USGA's Stimpmeter numbers for slow, medium and fast greens speeds for both regular and tournament play. I use it as a rough guide. So here we have arrived at the following: using 14 blade reels matched with a super thin bedknife on our Toro 21" walk behind mowers to cut greens daily, setting the mowing height at .110 inches and rolling 3 to 4 times/week we can attain a stimp reading of 10.5. Remember that weather and our practices such as verticutting (will actually slow down the greens) and light topdressing (will actually speed up the greens) can change everything.

Please give me your feedback. I will do what I can to satisfy your wishes (within sound agronomic practices and not beyond normal turf stress levels.
One more point. I know its been wet but its way better than 3 years of near drought conditions!
