Greens “watering”…

Surface temperature taken on a green at 1pm.

It is finally that time of year again where maintenance is becoming routine. We have reached a point in our maintenance schedule that has allowed us to get caught up with many areas on the two courses. While you will definitely see some projects that are ongoing; both courses have reached a maintenance level. This is all thanks to the extreme effort that our staff has put in over the last two months!

Over the next few weeks as the temperatures become consistently warm, you will notice staff members syringing the greens with hoses. Yes, we do have sprinklers and yes, we do water at night. However, overhead water can sometimes cause more harm than benefit. When temperatures get hot, and even more importantly the humidity increases, overhead is too much water and plays a significant role in disease pressure. Another downside to overhead water is that it isn’t able to really focus on the tiny little micro climates all over the greens. The hoses allow us to carefully monitor the moisture level and surface temperature level. We are proactively monitoring soil moisture with our TDR 100 moisture meters and constantly surveying the greens. We are not actually watering the greens, but simply cooling the surface atmosphere right above the plant. This practice, although labor intensive, ensures firmer, faster greens and less disease pressure. You will also notice us changing cups frequently throughout the afternoon. This is another proactive solution to minimizing foot traffic and turf stress. Please watch this short USGA video on hose watering:

The staff does not spend any longer than 3 minutes on a green surface. If you happen to be waiting to hit your approach, please wait just a few seconds longer to avoid hitting into them. They are paying attention to you, but they are diligently working to keep the green surfaces alive and playing well. Thank you for your understanding and patience. See you on the course!

The first significant Fall frost…

Frost delay is a term that will become common as the season starts nearing to an end.  These delays can sometimes be brief, but can also last as long as 3-4 hours depending on how quick and warm the atmosphere gets.  Frost is something that can be very damaging to grass especially when it is driven on or it sees a lot of traffic.  Frost forms even when temperatures are not necessarily at 32F.  If the sky is clear at night or early in the morning, a process called radiational cooling takes place.  This is when the earth loses heat and moisture trying to balance the earth’s energy.  Through evapotranspiration, the plant also loses moisture to the atmosphere.  If the temperature is cool enough, the cells inside the plant tissue start to freeze.  If the plant is walked or driven on, the cells can burst and potentially kill the plant.  This is why black tracks are typically seen in late Fall going across a fairway, tee, or even sometimes, a green.  Thanks to the GCSAA for this published article.  Please click on the link for more information, GCSAA Frost Delay Announcement

I understand that frost delays can be very frustrating, especially if you typically play early in the morning.  However, I ask for your patience and cooperation during these delays. It is definitely for the health and playability of the turf. We also ask for your cooperation in obeying the signs on both practice greens. I understand that walking is still allowed on the courses during a frost, but the practice greens typically see almost 50x the amount of traffic than regular greens. Practicing on these greens during a frost delay could result in severe turf injury or even death. We aggressively monitor the conditions and allow carts and traffic to resume on the turf as quickly as possible. Thanks for your understanding! See you on the course!

Lower Practice green under a frost delay. Please stay off until the sign is removed. Thank you!
