Greens Aerification and Lessons Learned

Well greens aerification is done with, but it doesn't quite feel like fall just yet.  Hopefully this week will be the last of the humid 90° days.  I would really like to be wearing hoodies and seeing this course firm up some more.  I feel that aerification went well and we were able to heal the holes in remarkable time due to some changes in our application recipe. The changes are explained below.

Growth Regulator -

           Throughout the year I use a growth regulator on all bentgrass, course wide in order to reduce clippings and keep ball roll up.  Depending on rate of chemical, rainfall, and temperatures, we can expect to get 10 to 21 days control from 1 application.  I use a lower rate on greens due to the lower height of cut and risk of injury, which will typically get us 7 to 10 days.  The bigger rate is for taller turf on tees and fairways, which keeps the growth at a minimum for up to 21 days.  This window fluctuates all year long due to the weather.  I could get deep into the weeds explaining Growing Degree Days, but I will spare you the boredom.  In order to keep the turf in constant regulation, the following application needs to be made somewhere around 170 to 200 growing degree days (GDD) on greens and 400 to 450 GDD on fairways after the previous app.  We have averaged around 27 GDD per day this year.  If we miss our window, then a huge flush of growth occurs and the place looks shaggy.  I missed the window a couple time this year.  If you cheat the window on the short side, you can injure the plant.  All that being said, we removed the regulator from the green's spray the week before aerification knowing that it would have slowed down recovery.  I heard the rumor that members thought I wasn't mowing greens anymore.  That is not true, they were just growing more throughout the day.

Growth Hormone Product -

            I also added into the spray tank, a product that I have become a big fan of.  It is a 3-way blend of plant growth hormones so I can get the plant to grow more without adding extra fertilizer.  I only use this product during aerification time or on new seedlings.  I sprayed it on the driving range tee and Holy Cow It Works!

So there are 2 things that cause me to lose sleep.

1. The Razorback football team going 2-10 again this year
2. Dying turf

The Hogs have found a QB now so we might get to 5 wins this year haha.

I have lost a little turf on green's surrounds and collars, but I am gaining on the cause and the fix.  Most of these areas just got too wet which led to its demise.  Holes 17, 11, 12, and 13 are the ones that are going to require some different management techniques.  On 17, the middle right collar is toast at the bottom of the valley.  I sent some samples to the University of Missouri for disease analysis.  There was some and we have sprayed for it, but the main cause was black layer that has formed due to this area being too wet and not draining properly. I have added a photo of the plug I took. This layer is only in the valley and prevents oxygen and water from reaching the rootzone. You can see the clean sand channel made from our aerification and new healthy roots are growing in those channels.  We are going to perform our drill and fill process on this area to break this layer up even more.

As for 11,12, and 13, they fall victim to minimal air flow and morning sunlight.  There will be a few less trees around these greens come spring.  The pattern of death around these greens seem to be similar and really makes me question the integrity of the green's drainage system.  I feel like water filters through the green, down to the gravel layer and then just sits there up against the native soil wall of the green cavity.  If this area is not properly drained then it will cause wet wilt and disease in the heat of the summer, especially if the green is closed in by trees. Since there are no maps, I plan on building my own drainage maps using my 3 foot probe to feel for drain line.....yes this stinks. There should be what they call a "smile drain" at the low end of every green which will keep water from building up against the cavity wall.  If we don't find one, then we will have to install one on these holes.  The good thing is that if the forecast holds true, then these spots will heal up nicely in a short amount of time, but that doesn't mean the problem is fixed.  

As far as the rest of the course, I am extremely pleased.  There was a point about 3-4 weeks ago when the course got pretty wet.  I apologize for this as firm is always my goal.  I believe that the sun angle and intensity changed as fall approched and I didn't react quick enough.  Even though we still had plenty of hot weather, our water table couldn't take anymore moisture and we got soft.  I had been lessening my irrigation output, but it didn't seem to help.  It just took me some extra courage to shut the whole thing off completely.  I believe that we have firmed up nicely once again now and that is the game plan from here on out.  I will keep you all informed on my drainage findings and plan in order to fix these issues. 

As always, please feel free to stop me on the course and ask me anything.

New Bunker Rakes

I would like to write up a small post thanking the Staley Farms MGA for the purchase of a 25ct. box of new bunker rakes.  That shows a good sense of pride that they would take funds out of their organization in order to better the golf course.  That also brought my attention to how poor shape our rake situation truly was.  So I also bought a box of rakes.  I switched to a brand of rake that I prefer that I hope will hold up better than the others.  Now I know that when a rough mower hits a rake handle, it doesn't matter who made it, its going to destroy the handle.  However, on our older rakes I noticed the teeth were breaking off like I had never seen before.  The 50 new rakes were able to get me through #9 fairway and from there on, I culled the best of the old rakes for the rest of the golf course.  I'm big on consistency, so over the winter I will purchase more of these newer rakes so that they will be the same throughout the entire course.  So along with speaking to my rough mowers, I have also placed stickers on each rake handle as I am sure you have seen.  The stickers say," Place Rake in Bunker".  The chance of a rough mower hitting the rakes will drastically be reduced if my bunker crew and each golfer will place the rake on the inside edge of the bunker after use.  I have included a picture of an example of placement.  I have also spoke with my bunker crew about the proper placement. Lets hope this will prolong the life of these new rakes. 

Deep Tining and Dying Weeds

Hello everybody and welcome to August.  Seasonal help is heading back to school and we are inching closer and closer to the start of Razorback football season!  I know, I know we aren't very good and there is this whole thing about we live in the state of Missouri, but it at least brings cooler weather to us all.

Today I want to share a picture and some videos from a couple tasks that were completed in the end of July.  I finally wrapped up Deep Tining tees tops which is just the beginning of creating a smoother, more consistent playing surface.  With this machine I was able to pop solid, 6-8" deep holes in all the tees to improve rooting and drainage.  I definitely found a couple tees that need serious water adjustments as you will see in the first video.  The front roller of the aerifier was acting as a squeege as it worked across a few tees.  Finding this is going to help us all moving forward as I will be aware of these areas in the future.  Also in the future, all tees will be verticut, topdressed, and core aerified which will bring us flatter and smoother surfaces.  Here is a video of me deep tining the blue tee on hole 12 and then a second one of the action of the machine.

The following picture shows some crabgrass and nutsedge feeling the affects of the herbicide that we applied to all tees after the aerifying.  We used a three way combo of products in order to kill crabgrass, yellow nutsedge, and goosegrass.  If you have noticed some weeds turning white on the the driving range tee, that is the goosegrass' reaction to one of the chemicals.  All tees will need a second application this upcoming week to truly knock out the crab and goose.  The nutsedge will be done just after 1 app.  We seem to have had crabgrass breakthrough on tees and there could be many reasons why.  Rainfall can play a big part in the breakdown of the pre-emergent, and we had plenty of that this spring.  Divots taken will also create holes in the chemical barrier which will then allow for weeds to germinate.  I believe I will try to split my application next year into 2 and see if we have better success.  

One other small note. We have begun mowing the native down.  It will take a while to finish this project, but I am hoping that we can spray a broadleaf herbicide behind the mow and control all the weeds now that they will be susceptible.  This should create a clean look as the grass grows for the remainder of the season.  We will mow it again once we are most of the way through fall. 

Well that is about it for this entry.  Please continue to stop us and ask questions whenever you'd like.  Hope you have a good time out on the course and thank you for all the kind words and support we have been receiving.

Summer is Coming

Well now that Stampede is in the rear view mirror we can all take a breath.  From what I could tell everyone had a great time.  I feel like the course responded well to the break in weather and should have been playing fast with the drop in humidity.  My team did exceptional and put in some long days to prepare the course for the event and I can't thank them enough for that. 

It looks like the upcoming 5-7 days will be bringing us some extreme heat with no rain in sight.  The fairways are starting to show signs of drought stress even though I have been watering them every night.  This morning I began applying a wetting agent to select fairways in order to hold in moisture, and I will finish tomorrow morning.  This will make the water I put out at night a lot more efficient, and with no rain in the forecast, we NEED efficient water.  This, in turn, has a chance to make the fairways a little softer in these areas which I know is not desirable.  If the result is unacceptable in my eyes then I have a different product that I can turn to.  My goal will always be to provide a golf course that I would want to play on myself, but my number 1 must have will always be living turf.

With the heat that is about to set in, I feel it is a great time to bring up the subject of ball mark repair.  The greens are now under a lot more stress and would really benefit from a higher percentage of correctly repaired ball marks.  I have added a link to a video produced by the USGA on the proper technique.  Please take a look and implement when you play your next round.  Poor #3 and #12 are getting annihilated.  I know that scalped plugs have been causing a lot of blemishes on the greens as well, and I believe that I have gotten to the bottom of that issue so those hopefully will be a thing of the past as well.

Try and stay cool and hydrated out there these next couple of months.  As always, stop me or Grant on the course anytime if you have any questions or concerns.

Putting Green Drill and Fill

As many of you have seen, Grant and I were doing a project on the upper putting green in the month of May.  We created a template out of a sheet of plywood and drilled holes in a portion of the green with a 12" long x 1" wide auger bit.  You could call it "a very aggressive aerification".  We were mimicking a process called Drill and Fill, but spending a mere percentage of the cost.  The area of the green we worked on was the driest part of the entire golf course due to the high clay and pea gravel content of that green's root-zone.  We removed as much material as we could with the auger bit, and then funneled in a new, clean material to help retain moisture and nutrients.  The product we used is a porous, ceramic granule that is commonly used in greens construction and aerifications.  We have already seen a positive change in the moisture levels of that area and I have added a video that shows just how much water those channels take now compared to the surrounding area.  Now if we could just tear off the second story of the clubhouse to alleviate the shade issue ha ha ha.

This is the process we are mimicking:

The Natives

In the month of June I finally found some time to begin spraying the native areas on the course.  So far I have completed the front nine and most of 18.  I am using 2 different types of broadleaf herbicides as well as a pre-emergant, and spray enhancer.  Goodness gracious that Milkweed is one tough cookie!  I know that my timing is late as far as controlling all the broadleaf weeds, but I am making an impact I believe.  Snowfall, ground moisture, and my start date all played a role in that, and going forward it is my plan to get the entire course pre-emerged much earlier in the year.  I also plan to attack the natives come fall and winter.  Every tree out there needs to be limbed up and freed of suckers.  I know this will make a big impact on the overall aesthetics of the course for the years to come.  We plan to mow all native areas once Stampede is completed, and then once again in the fall.   

 So there is this month's peek into my head.  Please continue to stop me and ask questions as you see me on the course.  I am really enjoying my time here at Staley Farms and lets try to keep Mother Nature on our side. 

Staley Farms Assistant Golf Course Superintendent: Grant Sherwood

I would like to introduce the blogosphere to Staley Farm's new Assistant Superintendent, Grant Sherwood.  Grant is already proving himself as a vital asset to our team and golf course though he has only been here for a month.

Being a native of Platte City, MO, Grant attended many years of summer golf camps at Shiloh Springs Golf Course.  This led to becoming a member of their course maintenance team and a passion for turfgrass management.  Grant took this passion to the University of Missouri where he completed his degree in Plant Science-Turfgrass Management.  He took advantage of internships at TPC Southwind, Trump National Bedminster, and Austin Country Club as well as volunteering at several PGA events.  Straight out of college, Grant accepted a job as Assistant Superintendent at Trinity Forest Golf Club in Dallas, TX where his team hosted the AT&T Byron Nelson.  After Trinity, he followed his passion for bentgrass to an Assistant position at Austin Country Club.  Side note..........wanting to grow bentgrass in Texas is nuts!!  A good, confident kind of nuts though.  This April Grant accepted the Assistant Superintendent position here at Staley Farms, a course that he has always held in high regard.  He is excited to be a part of the team and the pursuit for constant improvement. 

Verticutting Greens

Hello everybody, and welcome to my first blog entry.  Today I wanted to throw some information out there about the benefits of verticutting our putting greens.  This is a cultural practice that I plan to implement in the spring and fall each year.  Our team performed this task this past monday before mother nature opened the flood gates. The process uses many thin vertical blades to cut grooves into the surface of the green and then a light sand topdressing is applied to fill the grooves.  The cutting action removes thatch as well as a small amount of leaf tissue which allows better water, nutrient, and air infiltration.  Another benefit is a smoother surface which leads to a truer ball roll.  This is produced because the grain of the grass is reduced. This process adds stress to the bentgrass which is why I will only do this in spring and fall when I know the turf can recover well. Below I have added a picture of our practice green after the verticutting process.

In other news, my Assistant Golf Course Superintendent has started and is going to be a huge asset for Staley Farms and myself.  His name is Grant Sherwood and I will be adding his bio on this blog shortly.  

Mother Nature has told me that there will be no mowing this week and she is threatening me about next week being the same.  Staley has received near 4" of rainfall in the past 4 days.  We have been able to squeeze in greens mowing and that is about it.  So we have worked on some details like sprinkler and cart path edging. Hopefully this trend will change soon or we will be dealing with a large clipping mess the next time we do get to mow.  Until next time, hit em long and straight.
