We'd like to wish all our members and guests a Greate Holiday Season, and best wishes for the New Year!

The winter solstice occurs tomorrow, Tuesday, December 21, at 11:28 pm EST. The solstice marks the moment that the earth’s northern hemisphere is tilted back it furthest point from the sun, and the southern hemisphere is tilted is furthest point closest to the sun, - it is the shortest day in the north and the longest day in the south!

Beginning at 11:29 pm EST, the days will start to lengthen here as the earth begins to tilt opposite, and we will begin the transition towards spring!

Prior to the solstice, there will be a lunar eclipse which will begin Tuesday morning at 2:41 am, and will last approximately 3.5 hours. This is a very rare event – that a lunar eclipse occurs on solstice day!

Although it may not seem that solstices and golf go together, they are very much intertwined, as all plant life is dependent upon day light length...

Last Wednesday and Thursday Chris and I attended the New Jersey Turf Conference held in Atlantic City. We attended presentations on turf biology and disease, managing turf stresses, disease suppression and control, soils, and water management. The speakers included Dr. Bruce Clarke of Rutgers University, Dr. Peter Dernoeden of the University of Maryland and Dr. Bruce Martin of Clemson University. We also attended a seminar to get updated on pesticides and pesticide safety which was conducted by representatives of the NJDEP.

During breaks, Chris and I had plenty of opportunity to talk with other Superintendents and turf professionals about how we faced the weather challenges of last summer. We all talked about what worked and what didn’t. In the end, the consensus was that it was the hottest and toughest summer that any have seen, which wasn’t that much surprising…. But sharing our experiences with others was, and will always be, another way to learn.

As with any career, one can never learn enough, which is why Chris and I attend events such as this. Everything we learn gives us another tool to help you have the best conditions that we can offer.

It’s early December and the weather has made a decided turn toward cold! Just like all of you with residential sprinkler systems, here at the golf course we also need to get the water out of our pipes before heavy freeze causes damage. Our process for blowing out the irrigation system is similar to yours or your landscaper’s, but on a much larger scale.
We begin the week before our rented air compressors arrive, and let the system “gravity drain” for a day or two. We open some of the higher elevated valves to let air in the pipes, which in turn lets water drain into some of the ponds around the course. When water is no longer flowing out of our pipes we close all of our valves, attach the compressors to the main pipe outside of the pump house, and begin pumping compressed air into the irrigation system. We re-open the pond fills and let the air push out as much water as possible. Next, starting closest to the pump house and working away from it, we open every hose connection and run every sprinkler until nothing but air exits.
We literally have miles of pipe to empty, and 800 or so sprinkler heads and quick coupling valves that need to be emptied. Though we only make use of the compressors for two or three days, it takes about a week to complete our blowout. The goal is not to get every drop of water out of the system, but to get enough out so that if a deep freeze occurs, the pipes and sprinklers will remain undamaged. We have a pretty good process going and rarely do we see damage caused by ice. The process can be tedious, but it saves us an awful lot of trouble when we recharge the system the following spring!

One of the joys of the fall season, other than cooler temperatures, is witnessing the change of foliage on the golf course from green to yellow to orange and sometimes to red. Cooler temperatures are often accredited with this beautiful transformation, but another, more significant factor is at work here. The process by which trees shed their leaves is complex, but the reason for this occurrence can basically be attributed to shorter days, or reduced sunlight.
If you remember your high school biology, leaves are green because they contain chlorophyll. Chlorophyll is a green pigment which helps plants carry out photosynthesis. As days become shorter and the amount of available sunlight decreases, trees no longer have the need to produce or keep so much chlorophyll in their leaves. When days get shorter trees use a hormone called ethylene to start withdrawing chlorophyll from their leaves. A second group of pigments, carotenoids, get left behind. Carotenoids are yellow pigments which are present year-round, but are usually hidden by chlorophyll. So, as chlorophyll is taken out of the leaves, they take on the yellowed appearance of carotenoids.
Not all leaves stop at yellow. Some turn orange, or even red. This additional coloring is the result of the presence of yet a third group of pigments called anthocyanins. This set of pigments serves a couple of purposes. First, while the tree is busy removing chlorophyll and other hormones and nutrients from its leaves, it is pretty vulnerable to damage from the sun. Anthocyanins act as a type of sunscreen, allowing the tree to get ready for winter without taking too much damage. Anthocyanins are more often found in trees that prefer colder climates, furthering the belief that they act as protection from the sun. It is also believed that yellow leaves attract aphids, so trees have adapted to prevent this attack by turning their leaves red.
So there you have it! A hormonal response to shorter days gives us one of the most spectacular natural events that occur. Enjoy it while it lasts, miss it while it’s gone, and rest easy knowing we’ll see it again!

Did you ever wonder why I take the bales of straw used for fall clubhouse decorations and place them along the shores of our irrigation pond on #12?

Barley straw, as it decomposes, releases certain compounds that inhibit the growth of algae. It does not kill algae that is already present, but prevents new algae cells from forming, which is why its best to get it in the water before algae becomes an existing problem.

The breakdown of the straw also nourishes populations of “good” bacteria that help keep the water clean by eating up excess nutrients and pollutants.

Barley straw does not work in all instances – success depends on the pH of the water and the presence of dissolved oxygen. Luckily, our water pH is close to perfect, and we place the bales along the shores because the wave action there oxygenates the water.

They might look a bit out of place, but these bales help keep our irrigation water clean, and are a great alternative to risky aquatic herbicides which would negatively impact the turf that receives this water as irrigation.

As the weather continues to offer us cooler temperatures, frost delays become more common. Frost occurs when ice forms on the outside and inside of the turf plant. Ice on the outside is what we see, but the ice on the inside – frozen plant cells – is our worry. Pressure applied to frozen cells damages and breaks the cell membrane. Later, when the cell thaws, the cell fluids leak out, causing death of the cell. Unfortunately, in most cases, all the cells of the plant’s above ground parts are killed this way, and the plant cannot recover.

Sometimes it’s hard to be patient, especially when you’ve waited all week to get a round in, but it's one of those things that we cannot control or change. Maybe take the time during a delay to enjoy another cup of coffee, have breakfast, and talk with your friends…it might just make your day a bit better after all!

The USGA has a great animated explanation of frost delays in the link below.
