The A B C's of green speed

We have had an amazing stretch of weather in the last few weeks. Continuing "the year of firsts" theme I do not recall a stretch of constant wind, no rain and almost zero dew for such a long period of time. It helped create some fantastic playing conditions and also made the course look more like it does in August than May. I received a lot of great comments about the course and the greens in particular.I also received a few questions as well so I thought I would explain the basics of green speed here.

What causes friction? Obviously height of cut is on the top of the list.



 The most influential factor governing ball roll is friction. The more friction there is the slower the ball will travel and the faster it will stop rolling. What causes friction? Obviously height of cut is on the top of the list. Try putting on the fairway then the tee then on a green. The longer the grass the more surface area for the ball to contact and create friction. There is a point of diminishing returns however when greens are lowered beyond what the turf type you are growing can handle. A key factor for consistency throughout the day has been the use of plant growth regulators PGR's. It is common for greens turf to be regulated throughout the season. There are many benefits to using PGR's such as reduced water use, thicker stand,  but the main reason is for a reduced clipping yield. If the turf is not growing that much than the height of cut in the morning is similar to the height in the afternoon and so they should putt relatively the same. Assuming most greens are pretty close to the same height I would say moisture is the biggest player on putting greens for creating friction. Not only moisture on the surface or in the ground but also in the air. As the humidity rises in the summer the ball travels less due to the friction of all that moisture in the air. The same is true for putting. The weather conditions we had were absolutely perfect for ball roll. Low humidity, dry surface, and wind all helped create a firm playing surface. Add to that regulated growth and the greens were firm and fast all on their own.

Our greens have their most speed in the Fall when conditions mimic the ones we had recently. 


One procedure that has become popular again in golf course maintenance is rolling. Rolling helps to speed ball roll by flattening the grass blades so less surface area to cause friction. Courses that chase speed will roll often, sometimes even daily. Green speed should be set to match the budget, grass type, ability of players, and the contours of the putting greens. When green speed exceeds the contours of a green the balls roll off the surface which then slows play as golfers take 3,4 or more putts to hole out. This will also cause certain hole locations to be deemed unfair and limit the number of usable spaces. Our greens have their most speed in the Fall when conditions mimic the ones we had recently. My goal is to have healthy turf which provides a smooth consistent ball roll with a speed that is not deemed slow by current standards but also will not limit the areas in which we can place a cup. I also do not want the speed of greens to be a hindrance to pace of play. Based on the comments I receive we accomplish these goals. It is fun to have perfect weather to provide faster conditions naturally even if only for a short time.

Thank A Golf Course Superintendent Campaign



There is not a lot to update everyone on as we progress into the season. We continue to clean up the course. We added sand to bunkers. Seeded divots on tees for the first time. Took delivery of more sand as we prepare for Aerifying greens Monday, May 4th. The course is shaping up as temperatures continue to promote growth. The Tee up NE auction appeared to be a success from what I saw of the final bids. Mink went for over $300 so someone received the message and Thank You.
Speaking of thank-you's the video above came across my desk so I thought I would share it. The players here at Mink Meadows do not need the encouragement and the Members are some of the best I have ever had the pleasure to work with. There is a contest going on for golfers who participate, however and who does not like prizes?

Greening up! First Mowings


As a quick update things are progressing nicely. The saying is you cannot cheat the calendar so all though we had a slow start by a certain date everything is back to normal. The trees are budding, The osprey's are back, The turkeys too and the grass is starting to grow. Fairway Fred is back at it with the first mowing this week. We mowed tees also this week for the first time. The winter damaged areas on 3 green and the practice green do not look that much different and only time will tell whether they actually recover fully. The plugs I pulled out and grew in my office for a week were put back into the nursery and look pretty good so I am still optimistic.

New irrigation system computer upgrade
I spent a portion of last weekend driving to VT to help my son Josh pack up and move his belongings to a storage unit in New Haven CT. He has left Nectars night club in Burlington for a post as the stage manager of the former Paradise Theater which is being revamped and called College Street Music Hall http://collegestreetmusichall.com/concerts/. It is right across from the Shubert Theater. He has also secured a part time job back in the golf business at Race Brook CC. Now if he could only find a place to live his mother could start sleeping again. In the move he had an old monitor that I was able to procure. With the new irrigation software we installed a map feature. The new software is area based so having the map is a great way to re-train your brain away from the old number based system.
I have looked at the Tee-up NE auction and there are certainly some DEALS to be had. It ends Monday so check it out and help support turf research in New England.
