Today's Green Speed: Alive

This past week's temperatures put the "fire" into the holiday's fireworks!  With the exception of the practice tee, the golf course is comprised entirely of cool-season turf that isn't loving this summer's blowtorch conditions.  What does "cool-season" mean?

As the name implies, these species grow best in cooler climates, not in the blistering heat we've been experiencing.  During the spring and fall, we get root growth, but as the heat increases in the summer, plants lose root mass.  

During the latest heat wave, we heard many people say that after 15 minutes outside, they had to head back into the A/C.  Of course the turf doesn't have that option, and is baking all day, every day.  The challenges to turf health become exacerbated when there is no relief at night.  Low temperatures in the 80s don't allow for any recovery.  

So what changes are we making in our maintenance practices in these extreme situations to protect the course for the long-term, and what can you expect?  

Well, we don't stop mowing and we rarely (if ever) raise the height of cut on the greens--they are currently still being cut daily at 0.100".  However, we do back off on any cultural practices that can cause additional stress such as verticutting and topdressing.  Additionally, we may reduce the number of days per week that we roll the greens.  For greens in some of the more challenging growing conditions, an extra venting, using micro-tines has proven to be helpful in getting them through these weather patterns.  Lastly, if we anticipate temperatures in the triple digits, we may give the greens' sprinklers a spin during the day to temporarily cool off the turf canopy.

Green speeds will typically drop somewhat during mid-summer regardless of what we do.  The plants swell, and similar to how we feel in the heat, the greens may seem sticky.  We treat the greens like elite athletes, closely monitoring their inputs and conditioning protocols.  Pushing for fast greens at this time of year by lowering the height of cut, aggressive grooming, double-mowing, and rolling is ill-advised.  You won't find many athletes going for a PR in 100 degree heat!

And for the record, the greens were 11'3" on July3, and 11' 2" on July 4--we must have set the bar pretty high if players are saying the greens are slow now...

Why today?

Over the years, we occasionally hear comments regarding the timing of our maintenance practices.  This may include questioning why we need to spray "every time" you are playing a round.  While we try our best to avoid interfering with your enjoyment of the course, there are several factors that may impact what, when and why we need to make a plant protectant application (or perform any task) on a regular basis.

The reality is that at this time of year we are likely spraying one of the playing surfaces five days per week.  For example, the greens don't receive any granular fertilizer applications, so depending on the growth rate, we may be applying a nutrient spray weekly.  The primary rough is typically treated monthly, however if we see a need to pivot due to weather conditions, that timing may require a change.

A disease breakthrough in the rough warranted an unscheduled application last week.

With the course's round counts up by approximately 50% over the past several years, we have a challenging combination of increased maintenance needs on the course, along with fewer times to perform these tasks without encountering play.  In order to help with the issue, we have shifted our morning start time back by half an hour in 2026--this is the earliest it has ever been since the course opened.

Feeling Funky

We have been pushing the greens hard the past couple of months, and based on feedback, the results have been appreciated by players.  Of course, just when things appear to be running like clockwork, we get a curveball thrown at us.

What is sometimes referred to as "Poa funk"  appeared on several greens this past week.

While this might have some of the same visual symptoms that you would see with a turf disease, the cause is actually environmental stress and often appears in areas with higher moisture levels.  As you can see above, the aerification holes are green, and less likely to suffer from this funk.

By dotting the margins lightly, we can easily compare how things are trending from day to day.  More often than not, when these spots appear, they do not grow in size.  So we've got that going for us--which is nice...

Quick Fix

Many irrigation repairs are unplanned, which can make them challenging.  This past Thursday, a quick coupler (that we connect a hose to for hand watering) at #1 green broke off, leading to a river running down the approach and a deposit of mud on the front of the green. With this occurring 45 minutes before the first tee time, the team had to quickly jump into action.

While it wasn't the way we like to start the day, it was great to see the repair completed in less than an hour, with only one group having to play the hole as we worked on it. 

This does also highlight the fact that we have an irrigation system that was installed almost 38 years ago.  There is approximately 20 miles of pipe in the system, which is always under 115 PSI, whether sprinklers are running or not.

Bunker Basics

It might be a bit naive to expect that we would ever receive compliments about bunkers.  Realistically, if we aren't hearing complaints, we should probably chalk it up as a win.  What you might not realize, is that in order to achieve this not so lofty goal, it still takes a tremendous amount of time and effort.

Of course raking is a part of the process, but there is a lot more to it than just that.  Bunker surrounds must be mown by hand,  the bunker faces need to be edged, weeded, then the sand packed and rolled.  Additionally, sand depth uniformity is checked periodically, as neither too much nor too little sand is desirable.

Again, all of this takes a lot of labor.  Fortunately, the team is now at full strength and we are catching up on these tasks.

They're back...

It's been several years since it's even been worth mentioning Annual Bluegrass Weevils.  However, they appear to be back in force this year.  While most of their activity on the course won't catch your eye, the approach to #7 green may be the exception, as they had a field day in this area.  This is somewhat unusual given the control treatments that were made in April and May.

Last week we hit the collars with a larvicide to knock them out, so hopefully there won't be any more surprises this season.  One thing is for sure, a cold winter does nothing to set back this insect.

A dreary Memorial Day weekend, but...

Let's face it, this past weekend was probably pretty disappointing for anyone planning outdoor activities.  However, prior to this, it was definitely a good run as far as golf goes with the last "no cart" day being way back on April 2.

A soaked #9 fairway on Memorial Day.

While this was not great weather for spending time at the pool or working on your game, if nothing else, the golf course appreciated this multi-day soaking.  And despite all of this rain, it still looks like we will finish May below average in precipitation--this will be the 10th month in a row.
