Course Notes, 6/11/17


Talk about feast to famine.  A month ago, we received over 6.5" of rain at the golf course.  We have not had any measurable precipitation since May 28, quite telling by how our non-irrigated areas are starting to look.  A large thank you to those who came out to the Master Improvement Plan educational session last Tuesday, and for those of you interested, we have 2 additional ones this Tuesday, at 5:30 and 7:00 p.m.  Shawn Smith and Steve Forrest from Hills/Forrest will be here to answer any questions about the Master Improvement Plan that you may have.




4" rooting on greens.  A good thing heading into summer!
The summer's first dome of heat has arrived, and is bringing some high humidity values with it.  While rooting is at a tremendous level currently thanks to great growing conditions and a solid agronomic plan, in these cases we have to temporarily play defense in managing the fine playing surfaces so that they can survive until more temperate growing conditions return.  Our sprayers have been quite busy applying plant protectants to help fine turf ward off any potential fungal diseases from developing.  Managing water applications is critical during these stretches, and we have been leaning on the drier side when it comes to irrigation.  It may seem counter-intuitive restricting irrigation during a heat wave, but wetter soils can create a better environment for diseases to develop, while reducing the amount of root density in the turf.  Hand-watering hot spots and syringing greens in the afternoons is also critical for survival.  The USGA has produced a great video on water management, which you can view here.  Our staff will be out and about each afternoon watching conditions, and while we do not intend to disrupt your round, please use caution if a staff member is syringing on the hole you are playing.  This quite necessary procedure only takes a couple of minutes to complete and as soon as they are able, they will vacate the area so that you may resume your round.

Plant protectants applied in anticipation of first heat









If these above normal temperatures and humidity continue, other defensive measures may be necessary to allow the turf to survive until seasonable conditions return.  One example of that would be raising heights of cut slightly (.005").  This allows the plant to generate additional leaf tissue to produce the energy it needs to survive.  While defensive measures can lead to slower conditions, rest assured these measures are done to protect the turf though the tough stretches and allow us to return to normal maintenance when the weather allows us to.

Part of Zimm's Creek is now a lateral water hazard
The other change you may have noticed is a change in hazard marking along the lateral part of Zimm's Creek, right of 15 green.  The Golf/Greens Committee has decided that area is better defined as a lateral water hazard (red), based on the interpretation of the Rules of Golf.  The part of the creek running perpendicular to the green, and the pond will continue to play as a regular (yellow) water hazard.  For a more in-depth explanation of the definitions and how to play the ball if it enters these hazards, here is a link to the Rules of Golf explaining these.

Finally, I have some sad news to pass on.  One of our long time staff members, Rachael Garrett, passed away this past Tuesday.  Rachael served Elcona for 28 years and was a beloved member of our staff.  She enjoyed being out each day here among the members and beautiful scenery, and will be missed greatly.

If you have any questions, feel free to reach out to me at ryan@elconacc.com, or stop me when you see me out on the golf course.  Enjoy the week and stay cool!

Course Notes, 8/20/2016

A brutal stretch of rain, heat and humidity is looking like it is coming to an end.  Within the last week, the golf course has received over 6.5" of rain, and more is pouring down as I write this.  Many areas to the west of Elcona have received double the amounts we have, so I count my blessings that rainfall has not been greater.  I would like to take a moment and explain what is causing what everyone is observing out on the course, mainly on the greens.

Soil conditions now course wide are quite saturated and currently cannot handle even small amounts of water quickly.  Combine these water logged soils with daytime highs in the mid to upper 80's and heat indexes approaching 100 degrees, and it does not take long to create soil temperatures above 85 degrees.  These conditions create prime environments for disease and turf struggles, as roots begin to die off and they do not come back until soil temperatures consistently stay below 80.  Roots and turf that do not die off are quite easily susceptible to fungal diseases.

Pythium effects, 8 green
The brown areas of turf on some of the greens are areas that have succumbed to Pythium Root Rot.  This disease affects mainly the creeping bentgrass in the greens, as the healthy Poa annua surrounding it depicts.  With the weather and extreme soil temperatures we have experienced in the last 6 weeks, extreme environmental stress has finally shown us the symptoms of probable infection that occur during late spring.  We have treated all greens twice with fungicides to combat this pathogen, and a third will be coming this week.  A regularly scheduled venting of the greens is also coming Monday, which will allow us to poke .25" x 5" deep holes into the greens surface to dry out the rootzone and allow it to drain better, as well as promote new rooting and replacing harmful carbon dioxide in the soil with fresh oxygen.  The good news is that I am seeing new plant tissue emerge from many of these brown areas, a sign that the disease is in check and recovery is coming, which will be helped tremendously by the cooler weather coming this week.

Pythium effects, 3 green
Please note that recovery will take some time in these areas.   Any areas that do not recover will be plugged out from our nursery.  We have two large bentgrass/Poa nurseries that were established mainly plugs taken from our greens.  These nurseries are maintained exactly the same as the greens on the golf course and are an invaluable asset to have on hand.


Many of the collar edges and higher trafficked areas around the greens have also succumbed to the extreme stresses and traffic that the last 6 weeks have brought.  Populations of our old friend Poa trivialis (roughstalk bluegrass) that have emerged in the approaches have gone dormant from this weather.  Again, I am seeing new plant tissue emerging from these areas, so recovery is ongoing.

While I am not satisfied by any stretch with these current issues and conditions, the overall health of the golf course is good.  We will continue to be diligent with our maintenance practices to aid recovery and utilize all means available to return normal playing conditions as soon as possible.




 Finally, we lost a quarter of the large Burr Oak near 5 green (affectionately known as "Gus") Saturday morning.  This tree is estimated to be about 250 years old, and there are many cables that have been installed over the years to stabilize and balance its weight.  This morning one of the cables snapped, causing the southeast part of the tree to fall.  It has since been re-cabled and stabilized, but the area will be roped off to cart traffic for the time being.

If you have any questions, or would like to discuss the topics I mentioned above with me, please contact me at ryan@elconacc.com, or call me at my office.  I am more than happy to discuss and explain what is happening on the course with you.

Day 2: 18 Green Renovation

We had great weather today and made some major progress.  Day 2 of our renovation of 18 green involved staking out measurements for the new lower level, removing the rootzone mix on the lower level, and adding native soil to bring the front of the green to its new subgrade.  The rootzone mix is being stored near the cart storage barn until we can add it back to the new subgrade.  As with saving the existing sod, reusing this soil mix ensures that 18's rootzone will be consistent with the other 17 greens on the course.

Our plans tomorrow include compacting the new subgrade material to its final measurement and adding the rootzone mix back to the lower level.  Work will also be done on feathering out the new transitions within the design plans and rototilling the upper rootzone mix to final specifications.

Renovation of #18 green: Day 2


After a long day yesterday of stripping, rolling and temporarily laying the salvaged sod on the practice tee, we were ready for some action.  Significant progress was made with the removal of the existing rootzone material.  This material will also be saved and re-used once the sub-grade of the green is established.  By using the same sod from the original green as well as the original rootzone material, we are coming as close as possible to keeping the new 18th green as consistent as the other 17 greens.  Please click on the photos for a larger view.

Removing original galvanized steel irrigation pipe that was running through the
green.  we actually found the quick coupler that was located in the exact center of
of the green.  This is how the green was originally irrigated.

Progress at the end of Day 2.  It is now getting easier to visualize what
the final product will look like.
