#18 Cart Path Project

This week, the grounds staff put the finishing touches on the cart path expansion/curb project on #18 green.  This has been a much talked about and anticipated project and I am very pleased with how it turned out.  I would be remiss if I didn't mention and thank the City of Owasso Public Works Streets Department.  They lent a big hand by forming and pouring not only the curb, but the cart path as well!  We couldn't have done a project of this scale without their help.

All the signs and rope have been pulled and the cart path is fully accessible now.  Please use caution when stepping on fresh sod as it may shift under foot.

Here are a few pictures of the project:

Fairway Expansions

You may notice over the next few weeks certain areas in the rough near fairway edges will look scalped.  These are areas that we've selected to lower to fairway height.  Lowering the height of cut on these area should allow more landing area for tee shots and also give more room for laying up on certain holes.  The picture below is aerial image of the lower half of #11 fairway.  The green shaded areas show the existing layout of the fairway with the changes marked in yellow.  While adding this area to the fairway will give golfers a better chance to hit the fairway, it also brings the hills in the area more into play.

Over the next few weeks, we are also planning on making some slight changes to the fairways on #2, #15 and #18.  Stay tuned!

Thatch Control in Greens



Earlier this week the grounds staff completed a mini-tine aeration on the greens.  I call the process mini because often when the superintendent says the "A" word, golfers get concerned, and I wanted to convey the minimal effect the process will have on the playability of the greens during the project.  The small diameter of these tines allows for minimal disruption of the surface while still benefiting the turf.  As you can see from the picture above, quite a bit of organic material was removed from the greens.  Once the cores were pulled, they were blown off the putting surface and a heavy application of sand was added.  Once the sand was brushed in and rolled, the surface is very playable.  The finished product is shown in the picture below.

Each year, during the summer, the Bentgrass on our greens tends to accumulate excessive amounts of thatch.  Excessive thatch leads to a softer, less true surface that is more prone to ball marks, imperfections and disease pressure.  This shallow, mini-tine aeration has become another tool for our team to use to maintain firm conditions.  The tines do a great job of physically removing some of the thatch, while brushing the topdressing sand into the holes further dilutes the thatch in the top inch of the soil.  Reducing organic matter by replacing it with sand will allow us to maintain a consistently smoother, firmer surface.


Cart Path Extension at #18 Green


For many years, the area along the cart path at #18 green has been an issue.  Not only is it an eye sore, but years of shade and compaction from cart traffic have caused the Bermuda to thin.  The exposed soil eroded away and exposed the sandstone rocks beneath, creating a rocky mess.  As you can see from the picture on the right, this isn't a good last impression.  The other issue we have is the staff at Bailey Ranch has difficulty getting through this area while people are parked at the green due to a combination of the creek on the left side and the rocky uneven edge along the path.  The only option is to drive in the surround near the green which isn't ideal.

The plan to address this issue is to expand the current cart path from 6 feet to 12 feet and add curbing.  Adding the extra width will give golfers a safe place to park while on the green and will allow staff members through more easily.  As you finish your round, you'll notice the area along the cart path on #18 has been dug out in preparation for concrete.  The next steps will be to add a 2" layer of rock as a base, install concrete forms, and then pour the concrete.  Our friends in the Streets Division at the City of Owasso Public Works Department have graciously agreed to help us with this project as the scope of concrete work is beyond what us "grass growers" can handle.  With this in mind, we are somewhat at the mercy of their schedule as to when they can come complete the work.  The last time we spoke, they indicated they will try to pour the path some time in the next few weeks.

We ask for your patience and understanding while we work to make these improvements to the area.

Summer Cultivation of Bermuda




Although summer hasn't officially begun yet, the hot weather pattern has already set in and in response, the Bermuda throughout the golf course has begun to grow aggressively.  Once Bermuda begins to grow aggressively, it is time to begin cultural practices such as core aeration and slicing.  These practices alleviate compaction from cart traffic and maintenance equipment, improve soil oxygen and allow for deeper rooting.

Last Tuesday the staff began both solid-tine slicing fairways and core aerating tees.  As stated above, both of these practices will help alleviate compaction and help irrigation penetrate into the soil.  However, solid-tining does not remove any excessive thatch that might have accumulated.  We currently do not have the proper equipment to pull a core on fairways so this is the next best thing.  Once the fairway is sliced, it is mowed and all debris is blown into the rough.  The surface that remains is very playable.  The brown turf immediately around each slice mark is temporary and the turf will recover in a week or so.


The staff was also busy pulling a core on tees.  This process inherently creates more of a mess and requires more staff to clean up and get ready for play.  As you can see from the picture on the right, quite a bit of soil and thatch is brought up to the surface.  Once all the cores have been pulled, a drag mat is used to separate the soil from the thatch.  The soil reincorporates into the turf while the thatch is easily blown off using backpack blowers.  This process, although messy and inconvenient, is vital to the long term healthy of our Bermuda tees.  Without this process, our tees would be thin, discolored and would not meet the expectations of our golfers.









Cart Traffic Control


It's been about four months since we started painting red cart traffic lines in front of greens complexes, and I am encouraged to see so many people helping us keep carts away from greens.  To be honest, I wasn't sure how successful painting lines on the ground would be, but so far it seems to be a big help.  Signs are easier to see while you are playing but they have some down side.  They aren't cheap to purchase and they often get damaged and need replacing.  They also need to be moved by the mowing crew.  Painting the lines is convenient because it doesn't interfere with routine maintenance practices such as mowing.

Our intention for the lines is to keep compaction to a minimum and maintain the best turf quality in our greens complexes.  The grounds staff appreciates your cooperation with this program and look forward to seeing you on the course!

DryJect on Greens




This past Thursday, Robert Main with Turfgrass Solutions was on site to conduct another DryJect application to the greens.  This is the second consecutive year that we've asked Robert to come out to complete the process on the greens.  Last year, I wrote about how the machine works and the benefits that can be expected.  For those interested, that information can be found here.  One of the biggest benefits of the process is how playable the greens are immediately afterwards.  Typically after a core aeration, the greens are not very playable for a week or so.  The DryJect process actually makes the greens firmer, instead of softer, which gives the grounds department the ability to keep them faster and smoother than a traditional aeration.  The dime-sized marks that are left behind will heal in within the next 7-10 days.  As always, we appreciate your patience while we recover from the project.  If you have any questions about this, or any other topic, feel free to contact me.  Thank you.

Thatch Removal on Greens




Memorial Day weekend has come and gone.  The weather was perfect all weekend and the golf course was packed with hundreds of people enjoying themselves.  Based on the feedback I recieved over the weekend from golfers, the condition of the greens surpassed expectations.  It was nice to be validated and that all the hard work the staff has put into the golf course over the past few weeks has been noticed.  With the busy holiday weekend behind us, our focus switches to cultural practices on greens to ensure they stay firm and healthy through the summer months.

With this in mind, the grounds staff is performing a core aeration on greens.  Don't be alarmed, the tines we are using are very small and the debris created is easily cleaned up.  Once the green has been cored, a thin layer of sand is incorporated into the holes.  As you can see from the picture at the bottom right, the surface is very playable immediately after the process.

This coring physically removes the troublesome thatch and allows the topdressing sand someplace to go.  The improved oxygen content and reduction in surface compaction should allow the Bentgrass to be as healthy as possible leading into another hot Oklahoma summer.

Sod Work on Misc. Collars



This week, the grounds staff added new sod to a few miscellanous areas in the green surrounds on #2, #3, #10, #12 and #13.  A few of these areas came out of winter a little too thin and some of these areas were not level and needed redone.  One spot in particular, the area behind #3 green, had numerous sunken spots from years of gopher damage.  

Similar to previous sod projects, these areas will be marked ground under repair and we ask that everyone stay off the sod for the next few weeks.  Once the sod is rooted in, the soil underneath will stabilize and the sod will be ready for foot traffic.  After the sod gets established and starts to grow, the staff will begin lowering the height of cut down to it's eventual .4" cutting height.
