USGA Specification Greens at Olde Florida Golf Club

In 1992 we constructed the greens at Olde Florida Golf Club to specifications established by the United States Golf Association (USGA). Although we resurfaced the greens in 2000 to a new grass variety, TifEagle, the original subsurface was not changed.

Hurricane Irma Still Creating Challenges at Olde Florida

Last week, with the assistance of an outside contractor, we removed several dozen dead pine trees at Olde Florida. The pine trees died as a result of damage sustained from Hurricane Irma. When Irma moved through Southwest Florida on the evening of Sunday, September 10th, her powerful winds broke off numerous large branches, snapped trunks and shifted trees, disturbing the root system. 

When a pine tree receives severe physical damage it becomes extremely susceptible to pine bark beetles and borers. The insects usually enter the tree at eye level and above, and once they infect the tree, tiny holes, dribbles of sap or little dried mounds of sap can be seen on the bark.

The pine bark beetles and borers rapidly attack weakened trees killing them. When this happens, it is best to remove the infested tree(s) quickly so the insects do not move to nearby trees. The dead trees can also pose a safety hazard for golfers. 

Once the insects attack a tree there is nothing that can be done, but on healthy trees, bark sprays with an insecticide can reduce the incidence of attack. My staff has, and will continue making bark sprays on specimen pine trees that border our golf holes. Unfortunately, we will probably lose a few more trees at Olde Florida, but I am hopeful that the worst is behind us. 

Darren J. Davis, Candidate for President of the Golf Course Superintendents Association of America

It has been an honor and a privilege to serve on the Golf Course Superintendents Association of America (GCSAA) Board of Directors since 2012.

Since 1926, with a focus on golf course management, GCSAA has been the industry's top professional association. It provides education, information and representation to its nearly 18,000 members in more than 72 countries. 

Today, I find myself humbled at the thought of becoming the 82nd President of the GCSAA. The following is a link to my Candidate video and a Questionnaire  that provides some background information. 

The mission of GCSAA is to serve its members, advance the profession and enhance the enjoyment, growth and vitality of the game. I embrace this mission and I look forward to continuing my service to GCSAA members, promoting the profession, and with help from our allied associations, help grow the game of golf.  

The Shortest Day of the Year .... and Why it Matters

Today, December 21, is the winter solstice and that means it’s the shortest day of the year for those living in the northern hemisphere. Technically speaking, the winter solstice is when the sun is directly over the Tropic of Capricorn, or 23.5 south latitude. Non-technically speaking, it's the day when the sun rises and sets to our south at the lowest angle, and it marks the first day of winter.

Because the earth orbits around the sun on a tilted axis, between September and March the entire northern hemisphere gets less exposure to sunlight. Because of our location, it’s not a coincidence that these months coincide with the seasonal influx of residents to Southwest Florida and the play at Olde Florida Golf Club is at its peak.

In basic terms, for turfgrass to thrive it needs sunlight, the correct amount of water, adequate fertilizer and a good soil structure. Of these needs, the one that is least in our control is sunlight, which is why an understanding of the earths rotation and the winter solstice is vital.

Also influenced by the angle of the sun are air and soil temperature. Bermudagrass, the turfgrass that comprises the playing surfaces at Olde Florida, is a warm season turfgrass. That means it grows best when the average daily temperatures are above  75°F.  In addition, soil temperature, as influenced by air temperature is also important to the growth of bermudagrass. Soil temperatures above 65°F are required for significant growth, and the optimum soil temperature for root growth is around 80°F.

Since the duration and intensity of the sun's rays (and air and soil temperature) is out of our control, it is extremely important to have plant health peaking on this day and do everything in our control to maintain plant health for the next 60 days. By March 1, the nighttime temperatures have increased, the sun is high enough in the sky and  the days are long enough that sunlight essentially becomes a non-factor.

Hole 9 (pictured above) is the southernmost hole at Olde Florida Golf Club. The hole plays from east to west, so the sun rises to the southeast of  the tee and it sets to the southwest of the green.  On the day after the winter solstice, the angle of the sun will continue to shift slowly to the north until the sun rises to the east of the back 9 holes at Olde Florida. 

 

Turning Boards

During the winter golf season, the greens at Olde Florida Golf Club are single cut, single cut and rolled or double cut every morning in advance of play. The approaches to the greens, and the chipping areas around the greens are also cut several times a week. In addition, the traffic on and off the greens from golfers increases dramatically in the winter months. Consequently, extra care is important to maintain healthy turfgrass on the 48" collar that surrounds the putting surfaces.

To help reduce the wear on the collars, the golf course operations staff utilize turning boards from November to March. This is the time of year that the grass is growing the least, and the traffic from golfers and the mechanical stress from maintenance equipment is at its highest.

The turning boards we use at Olde Florida are made of high density polyethylene and measure 24" by 96". There are handles cut into each to help with the transport and movement of the turning boards. When cutting greens or approaches, each operator has at least four boards in their possession. When the green is being mowed, two or three boards are placed at each end of the green. The operator moves the boards after six to eight turns of the greens mower. The photos below depict the process.

Even with the turning boards in place, the collar and greens perimeters receive significant wear during the winter golf season. To help reduce compaction and encourage growth the collar and greens perimeters also receive periodic supplemental fertilization, hand watering and solid tine aeration or water injection aeration during the winter golf season.  

Hurricane Irma Update, Golf Course Reopens

Two weeks ago yesterday, Hurricane Irma devastated Southwest Florida. Much of the region is still in recovery mode and will not be back to "normal" for many months. However, I am pleased to report that Olde Florida Golf Club will be open for play tomorrow morning, September 25.

The club was previously scheduled to be closed for golf course cultural practices last week (September 18 - 25). If you have read my September 14 or September 20 blog entry you are aware that no aerification, vertical mowing or other routine maintenance tasks took place last week. My staff was focused solely on recovery efforts.

By the end of the day, all of the lakes will be at "control" level   

Below are some "before and after" cleanup drone flyovers of hole 12, 16 and 17. There is still work to be done, but "tree line to tree line" we are in VERY good condition.

The final step in the cleanup efforts is to remove silt from the floor of the bunkers and level the sand to a consistent depth. That will occur before tomorrow morning. Over the next few weeks, additional sand will also be added to replace what was lost from the winds of Hurricane Irma and the torrential rains we received this summer in Southwest Florida. Sand will be added to achieve a consistent 5" depth in all of the bunkers.

Year to date Olde Florida Golf Club has received 83.89" of rain. The majority of this occurred this summer. In June we received 22.56", in July 17.23", 17.58" fell in August and so far in September we have had 17.15"

See you soon!

Hurricane Irma Recovery

As detailed in my September 14 blog entry (click here) the eye of Hurricane Irma crossed over Olde Florida Golf Club on the evening of Sunday, September 10 causing significant wind damage and flooding. While there is still a great deal of work that needs to take place, I am extremely pleased with the significant progress that has been made to return the golf course and all facilities to pre-Irma condition.

Due to the extensive flooding on the golf course, and the inability of my staff to get to many of the holes on the golf course on the days following the storm, our initial efforts focused on removing trees, limbs and debris from the incoming road and clubhouse. This is a link to a video of one of the many oak trees that were uprooted by Irma and needed to be cut in pieces with a chain saw and dispersed with our Vermeer chipper (click here).

When staff was able to return to work, Tom and his personnel had the primary focus of removing plywood from the clubhouse windows and doors. After this was complete, his staff assisted mine in the cleanup around clubhouse by raking and removing the smaller debris from the landscape areas.

As the water receded, beginning with the driest holes, my staff went hole by hole to remove trees and other debris on the turfgrass. The greens took first priority. Fortunately, no trees fell directly on any of the greens and only minor damage occurred to the putting surfaces.

Debris removal from turfgrass took priority over other areas. The turfgrass took precedence in order to minimize turfgrass damage or death from lack of sunlight. Due to the hard work of my staff, the lack of additional heavy rainfall following Irma and the quick drop in the lake levels, I am very optimistic that we will have minimal turfgrass loss.

Cleaning perimeters, landscape areas between golf holes, and things such as removing this palm tree, which Irma lodged in an oak tree between hole 10 and 18, will occur as time allows.

Many of the Olde Florida staff were without power for well over a week after the storm making life very challenging. With any challenge the opportunity for a positive reaction exists. Olde Florida has always had a "TEAM" approach (Together Everyone Accomplishes More). This was certainly the case in the aftermath of Hurricane Irma. When Tom didn't need his staff in and around the clubhouse, they assisted my crew on the golf course. In addition, Tom and I decided having a group lunch each day in the grill room would enhance the "team" concept and show deserved appreciation to the entire Olde Florida team.

I hope that you are having a great summer and your Naples residences did not incur extensive damage. I am looking forward to another awesome winter golf season!
