Golf Course Update

After four back-to-back winters in a La Niña weather pattern, with numerous heat records and ample sunlight, this year we experienced our first El Niño weather pattern since 2018-2019. This winter turned out to be an extremely strong El Niño weather pattern, resulting in the most difficult winter to manage turfgrass in my 31-years at Olde Florida.

El Niño is a climate interaction linked to warming sea temperatures in the central and east-central Pacific Ocean. The warmer waters cause the jet stream to move south of its typical position. During an El Niño winter, the southern 1/3 to 1/2 of the United States experiences cooler than normal temperatures, increased cloud cover and enhanced precipitation. 

The challenge with above average precipitation in the winter months is; with low evapotranspiration rates the soil remains saturated, decreasing oxygen and limiting root growth. Combined with the extreme cloud cover (the cloudiest December and January in over 83 years) growing grass was very challenging.

My staff and I worked diligently and did things never needed in all of our previous seasons. Among other things, disease pressure required increased fungicide applications on greens, tees and even fairways. As a point of reference, we are currently 40% over the annual fungicide budget, with 6-months remaining in the fiscal year.  Other adjustments made to combat the weather challenges included increased solid-tine aeration, higher heights of cut and reduced mowing.

El Niño's Effect In Florida: Explaining It To Golfers, Boards and Owners

When sunlight finally returned to normal levels in February our hard work this winter was rewarded and we have finished the 2023/2024 winter golf season extremely strong!

Purity of the TifTuf turfgrass, planted as part of the 2021 renovation remains very high. The goal was 99% eradication of the existing grass during the 2021 renovation, and we achieved that. As of the 2023/2024 season, we are still at approximately 97-98% purity. This level will drop slowly each year.   

This summer we will continue similar work that has been performed in previous years. This includes cultural practices such as aerification, vertical mowing and topdressing. Last year we expanded our topdressing of tees and greens to include fairways. All of the fairways received 1/4” of sand. The fairways on holes 2 & 8 (our wettest fairways) received an additional three 1/4” topdressing applications for a total of 1” of sand. It is a significant investment, but it results in firmer, better draining fairways.

For an explanation on why we perform these practices please visit my July 2023 blog entry: "Why Do You Aerify Greens When They Are In Great Condition?"

The cultural practices we perform annually in the summer months greatly assist in winter conditioning. They are also crucial to survive challenging weather patterns.

Drainage, tree trimming and underbrush maintenance are also routine summer projects.  Last summer my staff installed 1,700 linear feet (1/3 of a mile) of subsurface drainage. That brought the total subsurface drainage that my teams have installed in the last 30 years to over 16 miles.

For more on the drainage work we perform please visit my August 2023 blog entry: Drainage...Drainage...Drainage!!!

Golf Cart Usage

I would like to thank the majority of the membership who are driving golf carts responsibly and according to club policy. As a reminder, we ask that all members and guests keep golf carts off turfgrass around tees (exiting the path after the last green and white post) and keep carts outside the green and white posts around putting greens. Your adherence to this policy will benefit your fellow member and provide the highest quality turfgrass for everyone to enjoy.

Vanderbilt Beach Road Extension Update

The Vanderbilt Beach Road Extension project is a 7-mile extension of the existing six lane.  The extension will begin to the west at Collier Boulevard and it will end at 16th St. The county estimated the project will take approximately three years to complete. The project began in the fall of 2022.

Subsurface work on the road work and the new canal excavation continued this season. This has created a few challenges with dust. I am pleased that the contractor hired for the project by Collier County, Sacyr Construction has been extremely responsive when I have reached out for assistance and updates.

In the near future all existing connections (outfall and intake pipes) into the old canal will be extended to the new canal. When completed the existing canal will be filled in. Next season (2024/2025) paving at our end will occur and if they stay on schedule, the project should be complete in the fall of 2025. Unfortunately the 8’ chain link fence and planting on our southern property line will not be complete until the end of the project.

El Niño’s Effect in Florida: Explaining it to Golfers, Boards and Owners

Recently I was asked by the Golf Course Superintendents Association of America (GCSAA) to co-present a webinar that addressed impacts the strong El Niño pattern was having on golf courses. The title of the webinar is, “El Niño’s Effect in Florida: Explaining it to Golfers, Boards and Owners.” A link to an abridged copy of the webinar can be found HERE


I was joined by J. Bryan Unruh, Ph.D.University of Florida. Dr. Unruh is an Associate Center Director and Professor of Turfgrass Science. Unruh focuses on providing real-world solutions for today’s turfgrass manager. His work centers on water quality (nutrient leaching and runoff) and quantity (drought) concerns, pest management, and new turfgrass cultivar development.


Over 200 GCSAA members registered for the webinar. After completion, a link to the webinar was posted on the GCSAA website so it could be shared with golfers, facility board of directors and owners to explain how golf course superintendents deal with weather, and weather extremes such as strong El Niño and La Niño patterns.


December and January were the cloudiest in South Florida in 83 years

How Does Turfgrass Eat?

When humans are hungry we eat. If we didn’t, we wouldn’t survive. 

Have you ever thought about how turfgrass gets food? In the form of a formula it looks like this: 6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2.  You might have learned this in high school botany class. This is the formula for photosynthesis.

All plants (including turfgrass) are called “autotrophs” because they use energy from light to make their own food source. Many people believe plants are provided food when nutrients are applied in the form of fertilizer. While a balanced soil and nutrient applications are necessary, the reality is plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and it is performed by all plants.

There are many steps in photosynthesis, but the last requirement is an important one because it provides the energy to make sugar. The final step is the Sun!

The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make sugar (glucose). After the sugar is produced, it is then broken down into energy that can be used by turfgrass for growth and repair. 

The bottom line is without sun a plant can’t create food and regardless of what inputs we as turfgrass managers provide, or the management we perform, without sun turfgrass doesn’t survive.

Recently I wrote a post El Niño and it's Effect on Turfgrass Management  In the post I provided data that showed December was the cloudiest December in South Florida since 1940. Recently the same data was released for January. The data (below) shows that January was also the cloudiest since 1941. This makes the back to back months the cloudiest in 83 years!


While it has been a challenge, due to various management strategies we have maintained turfgrass cover on all playing surfaces. Without a doubt, it hasn't been an easy task! 

With the Winter Solstice behind us, (Link to blog entry on Winter Solstice) we'll have the opportunity for another minute a day of sunlight, and with the winter we've had, we will take every minute we can!

El Niño and its Effect on Turfgrass Management

After years of back to back La Niña winters in Southwest Florida, we are experiencing our first El Niño weather pattern since 2018-2019. El Niño is a climate interaction linked to warming sea temperatures in the central and east/central Pacific Ocean. The warmer waters cause the jet stream to move south of its typical position. 

During an El Niño winter the southern third to half of the United States experiences cooler than normal temperatures, increased cloud cover and an enhanced chance of precipitation. 

Forecasters for the National Weather Service have said there is a greater than 55% chance of a "strong" El Niño weather pattern and there is even a 35% chance that it ends up being one of the strongest ever, like the ones we saw in 2015-2016 or 1997-1998. 

NOAA Seasonal Precipitation Outlook for January - March 2024


NOAA Seasonal Temperature Outlook for January - March 2024


As a result of back to back La Niña winters, the weather in Southwest Florida the last three winters was exceptional. In a La Niña winter the climatical conditions favor warm-season turfgrass growth. The above average temperatures, lower than average rainfall and bountiful sunshine enable turfgrass to thrive. The weather, combined with management by the agronomy staff produced exceptional conditions at Olde Florida! This also allowed us to be very aggressive with vertical grooming and maintain very low heights of cut on putting surfaces, resulting in exceptionally quick green speeds.

Winter rainfall is dramatically different in El Niño, Neutral and La Niña weather periods

An El Niño winter creates challenges for growing turfgrass (or any crop) in Southwest Florida. Fortunately, as is the goal every year, we entered winter with very healthy turfgrass. This is in large part due to the cultural practices we perform in the summer. Aerification, topdressing and all of the off-season turfgrass management enable us to survive the busy winter golf season, even when the weather is least conducive to warm season turfgrass growth. You can read more on the challenges of growing warm season turfgrass in the winter in my recent blog entry: "All I want for Christmas ... is sunshine!"


South Florida Experienced the Cloudiest December since 1940

This year, as we entered December it became obvious the El Niño forecast was correct and we reacted quickly. Our management in December and January has been drastically different from previous winters!  Due to reduced sunlight and cooler temperatures turfgrass growth quickly and drastically declined in late November. 

Among other things, growth regulation was halted, the height of cut on greens and fairways was increased and mowing frequency reduced. The advantages of both include reduced stress, increased leaf tissue and consequently deeper rooting.  Increased leaf tissue also enhances photosynthesis. Without getting deep into plant physiology, a plant needs sunlight to survive and it's the leaf tissue that absorbs sunlight enabling photosynthesis and subsequent growth. 


Although we raised the height of greens in December, I would point out that the increase was extremely minimal. Our lowest height of cut on greens in the 2023-2024 winter season had been .090". Our current height of cut (on January 4th) is .115". The difference in our lowest to our current height of cut is .025". To give perspective on this slight change, the diameter of a US dime is .053. Consequently, the raise in our height of cut is LESS than one-half the thickness of a dime.  

Disease pressure this winter has also been amplified by low light, cool temperatures and moist/saturated conditions combining to weaken the plant and create a desirable habitat for pathogens. We implemented several practices to elevate this challenge. We began needle tine and air injection practices on the greens. This increases air into the subsurface increasing drainage and soil oxygen, as well as relieving compaction. 

We also significantly increased our applications of plant protectants on tees, greens and even fairways. On greens, all potential soil and leaf diseases were addressed preventatively with systemic fungicides, and when needed correctively with contact fungicides. We also increased the frequency of light rates of foliar fertility on greens to try and encourage growth in this period when the plant is not actively growing from the nitrogen in the soil.

Year in Review: 2023 in Photographs

A new year brings excitement for the future, but it's also a good time to reflect on the past. I find that self reflection provides the opportunity to appreciate the things you experienced and discovered, as well as determine the things that made you happy. I enjoy photography so one way I reflect on the previous year is to sort through photos I took in the last 12 months. These are a few of my favorites.
