Course Notes, 8/26/16



After a week of cooler weather, turf has begun to breathe a little easier and recover from July and August's stretch of weather.  Club championship week is in full swing and hopefully most of you have taken advantage of a break in the rain to enjoy your golf course.  

On the greens, rooting depth has increased in the last two weeks to an average of 2 inches, and they are turning color from brown to white, a good sign of a healthy plant.  I have continued to see new shoots pop out of areas that were effected by Pythium Root Rot, which I wrote about here.

While I mentioned that recovery will take some time in these areas, we have taken another proactive step to help aide recovery by hand seeding these areas.  Below are some pictures of how this process works.  Further actions we will be taking include applying a light amount of granular fertilizer next week to help these areas grow in, and following Labor Day, a growth regulator application (normally applied weekly) will be skipped to further promote recovery.

Course Update: Greens and Green Surrounds

By now it should not be a surprise to any of you when I say that there has been a dramatic change in course conditions in the last 4-6 weeks. The extreme heat has finally taken its toll on the greens as well as the turf surrounding greens.  Please indulge me while I make an attempt to explain what is happening in each of these respective areas.

While the stress from the heat on the greens may not be visible on the surface, there are plenty of symptoms visible below the surface. Throughout the spring and early summer we had some fantastic root growth thanks to a strong agronomic program and some great growing conditions.  Unfortunately, once soil temperatures reached 80 degrees and higher, the roots began to die off and will not return until temperatures consistently drop below the 80 degree mark again.  With the record setting high temperatures this summer and lack of rainfall, we saw some unbelievably high soil and canopy (surface) temperatures which severely impacted the health of the greens.  Please see the photos below for root depth comparison photos as well as soil and canopy temperatures.

is not good either!
For those of you wondering why the greens are so soft and why green speeds have been slower even though the weather is showing signs of cooling off, this picture showing the current rooting depth is the reason.  When roots are this shallow, or even non-existent in some cases,  we have to be extremely cautious not to add any additional stresses to the turf that would give it a reason to die off.  We are constantly on the lookout for any signs of wilt and regularly syringing the greens to keep them cool. As you can imagine, it doesn't take long to dry out and for the condition of the greens to head in the wrong direction.  As Mother Nature hopefully begins to think about cooler weather patterns, new roots will be initiated and our regular management practices will return to normal. Ironically enough, we have now entered a rather wet stretch of weather that will help recovery, but with the lack of roots less moisture is being removed from the soil which also helps contribute to softer conditions. We continue to roll on a regular basis, but we are also promoting improved plant health which has led to additional growth. Please keep this in mind as you enjoy your round and stay tuned for an upcoming post on the hidden factors of green speed.

Regarding the poor conditions around several of the greens, we are once again battling our old friend Rough Bluegrass (Poa trivialis). This is now the third straight year of extremely hot weather, and it's no coincidence that this is the third straight year that we are facing poor conditions around the greens (this year being the worst). Under high temperatures, this turf, much like Annual Bluegrass, does not want to survive.  It enters a state of dormancy and will not recover until weather conditions are more favorable.  More often than not, full recovery, if at all, will not occur until the following spring. Because of this, we have elected to begin replacing these areas with Kentucky Bluegrass purchased form a local grower.  This will provide a quick fix to the problem and will also minimize the chances of these conditions returning in the future.

present, only the stolons.  Most of these areas can be rolled
just like a carpet because of poor rooting.

Please know that I am less than thrilled with these conditions however, given what we have been through this year, the overall health of the golf course is quite good.  Sure, we have plenty of black-eyes and are bruised from the fight, but we live to fight another day. Our gloves are still on as we have no plan on giving up and want to finish the year on a very positive note as we head toward the various club championships. Enjoy the remainder of the summer and hope for some cooler weather.

I Know the Benefits, Do You?

It is that magical time of year when the most common phrase heard around the club is: "Just when the golf course looks great again, you are going to destroy it".  The short response to that is Yes, yes we are, but only with the goal of creating healthier turf, and the "destruction" will be short-lived. 
It's aerification time! After an extremely difficult summer, I can think of no better way to help finalize our recovery than by aerifying all major in-play areas.  Many of you probably understand the basics of aerification, but do you truly understand the long term benefits and why there is the need to perform this task multiple times each year?

This photo shows the importance of aerification. The long roots
are taking advantage of the better growing environment in
an aerification hole, while the shorter roots are not
growing in an aerification hole.
 
Everyones first reaction to the benefits of aerification is that it reduces compaction.  While this is true, it most likely is not the most importanat benefit, especially on greens. Creating openings in the soil profile, regardless of whether it is a green, tee, fairway etc. is the primary goal of aerification.  As the name implies, it creates an opening in the soil that will allow for more air (oxygen) to penetrate the soil leading to enhanced root and plant growth.  The holes also lead to an increase in water infiltration.

Another benefit of aerification is the removal of organic matter and thatch. All of our playable areas have very manageable levels of thatch due to our commitment of regular and timely aerification. Do not take this as a sign that we can become relaxed in our approach. If we allow our thatch to begin increasing again, we will be creating a more favorable environment for disease, which, as we saw this summer, we don't need any more of.  Thatch is also capable of holding many times its weight in water.  What does this mean? Softer and wetter conditions. Nobody, including me, wants this.

This is certainly an older photo, but it gives you an idea of how
much soil and thatch is removed. We are now aerifying greens, tees 
and fairways on different weeks to minimize the disruption and
give us ample time to make sure the process isn't rushed.

After summers like the one we had this year, I can't imagine what we would have been faced with if we didn't have the commitment to the cultural practices that we do.  Beginning with spring aerification to the venting of the greens on a regular basis throughout the summer months to the fall aerification that we are now preparing for.  All of these go hand-in-hand and allow my staff and I to provide you with the conditioning that you have come to expect.

As witnessed this season, our program does not always guarantee perfect, disease free conditions all of the time, but it does help set us up for success even during a difficult stretch of weather.

I know that this process is typically not well received and that the timing never seems right, but we must complete this process while the weather is good and while the turf has enough time to recover before the long winter sets in. Since we have purchased two new aerifiers, we can now, with the help of good weather, have all 26 acres of fairways aerified and cleaned-up within three days (last year we were done in two days). Historically, this has been a week long process or more. Remember, the long-term benefits drastically outweight the short-term inconvenience.

Think dimmer switch, not light switch.

After a long and very difficult stretch of weather during most of July and the first part of August, many of the stressed areas on the golf course have begun to heal. When we come to the end of stretches like this (not that we have had one this severe before) it must be understood that we cannot, or will not, rush right back into our normal maintenance practices. Currently, we continue to mow at a slightly higher height of cut on the greens, but a rolling schedule is slowly being introduced since the density on the greens is improving.

The damage that occurred happened quite quickly, but it will take awhile to reach full recovery.  The best analogy I could come up with is a light switch.  We can't just flip a switch and be back to normal.  We have to slowly ramp back up (like a dimmer switch) until we reach normal conditioning. If we rush into recovery, we run a very high risk of taking a step backwards.  Obviously, this is not something we want to see happen.

Cutting Bentgrass sod from our nursery for use on the golf course
After the previous paragraphs, this next statement will probably sound a little hypocritical: I am not very patient when it comes to recovery. With that being said, a number of the larger areas in the fairways that were damaged from the Pythium Blight (see previous posts) are being repaired with sod, as opposed to waiting for seed to germinate.

When recovering from a summer like we have had, the importance of a good nursery is invaluable.  The Bentgrass that is grown on the fairway nursery (see picture) is the same type that is found on our fairways.  Because of this, when it is installed on the golf course, it is a near perfect match and should blend in immediately. We currently have two greens nurseries (established from plugs of the greens on the course), two Bluegrass nurseries and a very large Bentgrass tee/fairway nursery.  Each one of these nurseries is maintained like their corresponding areas on the golf course so that if the need arises, it can be used and have an immediate impact.


On the disease front, we continue to struggle with the disease Summer Patch (Magnaporthe poae). This is not a new occurrence and we have battled with it before. Luckily, it is not as widespread as it was a year ago. Fertility on the greens has been increased and multiple fungicide applications have been made to help with recovery.

An area on #14 green that was affected by Summer Patch, but is now recovering. Notice the Bentgrass moving into the voids where the Annual Bluegrass was prior to infection.

Lastly, as we continue our recovery, I would like to thank the membership for their support during a year that nobody would like to repeat.  Knowing that there was support behind the tough decisions that were made and that there was, and still is, support as we heal and repair damaged areas, made the season a little more tolerable. This is not the end of the golfing season, hopefully just the end of the stressful weather, so get out and enjoy your golf course!

Course Update: Time for Recovery



I hope that everyone was able to make it out to the club this week to enjoy watching some fantastic golf.  I couldn’t be happier with the condition of the golf course and I feel that it put up a pretty good fight for the best golfers in the state.  My staff has worked extremely hard, not just during the tournament, but, in the last day or so to get the rough mown, divots filled and debris picked up all before you get back on the course today (7/15).  I would like to thank each one of them for their long days and dedication to Elcona as well as their desire in wanting to showcase the club during a very important week. With that being said, the course is now ready for a break before we head into Invitational week. 

The winner, Brian Maurer, being interviewed
Looking ahead to the forecast for the weekend and into next week, it appears that we are headed for an extremely warm and humid stretch of weather. Last year, about this same time, we had a similar weather pattern that contributed to an outbreak of Anthracnose on the greens.  Because there is already some slight damage from Anthracnose on a few of the greens, we are going to be extremely cautious as we head into warmer and more humid weather.  Unlike last year, we are currently planning to mow at the same height, but our rolling frequency will be reduced.  We have also skipped an application of our growth regulator in order to promote some additional growth and speed the recovery process after a long week.

At this point, there is no reason to panic.  We are merely taking a proactive approach toward protecting the greens so that we can be ready to showcase the club for the 50th anniversary of the Walter O. Wells Invitational.

On Monday (7/18) the golf course will be closed so that a planned venting and topdressing of the greens can be done.  This has been done once already this year and has paid huge dividends with respect to the overall health and playability of the greens. 

More on venting in a future blog post.  Stay tuned!
