June 2023 GCM Update

Summer has officially begun at Copperleaf! We have fortunately been receiving steady rains to help fill up our lakes and provide the Golf Course with some much needed moisture.

The turfgrass on the Golf Course is in excellent health as we begin to put plans in place for our major cultural practices scheduled to occur during the three-week July closure. 

The recent summer rains have balanced out our aesthetics and
filled up our lakes.

Our annual Curfew soil fumigant application was successfully completed during our June, three-day closure. Curfew is a nematicide applied to eradicate parasitic nematodes in turf. Nematodes are microscopic roundworms that feed on plant tissues. Each year, this product is applied to control nematode populations to ensure that our turfgrass is healthy and performs to our high standards. The slits from the machines have left temporary scars, as expected, and should be healed in the next week or two. We recently applied a bulk fertilizer application to the entire golf course which will expedite the recovery process.

The Curfew application is completed by injecting the product
5-7" into the soil. 

Temporary linear scars can be observed for 2-3 weeks
following the application. 

With the warmer temperatures and active turfgrass growth, we have been routinely vertical mowing (verticutting) our putting surfaces. Verticutting is accomplished by utilizing a mower with thin blades that cut vertically into the green. This practice is completed to remove excessive leaf growth, improve surface smoothness and promote upright turfgrass growth. 

Our Summer Annual flowers were installed earlier this month. Red and Green Coleus have been planted and are growing in nicely. The red and green color contrast will offer enhanced aesthetics around our key areas of the entrance and clubhouse over the next several months. 

We have recently started the process of preparing to install turfgrass to a large area in between holes #16 and #17. The Greens and Grounds Committee has supported the idea to eliminate a large section of pinestraw and native grasses. In the past, this bed was nearly 400 yards long consisting of native grasses, palm trees, olive trees, and other native plants. Unfortunately, this extremely large area was very popular for golf balls, in addition to consuming a great amount of our time and resources in both trimming and weed control. During our July closure, we will harvest sprigs from our fairways during the verticutting process, and then plant this area with Celebration bermudagrass. We are confident that the pinestraw bed reduction will be aesthetically pleasing and much easier to play from, with a secondary benefit of helping pace of play.

During the aerification process, we will use sprigs generated from
our fairways to plant this area with Celebration Bermudagrass,
matching our existing turfgrass.

Ornamental grasses, native plants, and pinestraw were removed in
a large section of the bed located between holes #16 and #17.

A view of the project from #17. The existing palms and trees
will continue to offer separation between these two holes,
but playability and aesthetics will both be enhanced.

May 2023 GCM Update

While we are now in the rainy season in southern Florida, we are missing the...rain. It is seemingly raining everywhere but Copperleaf, but I remain optimistic that will come very soon. As of today, the lake levels are the lowest they have been in my nearly 2 years at Copperleaf. We are continuing to selectively irrigate dry areas through the day, but our supply is quickly diminishing. Fingers crossed, we will soon receive the much needed rain to fill up our lakes and balance out the turfgrass aesthetics.

Our new butterfly garden continues to thrive with several species of butterflies having found this new location. With its early success, we are likely going to be expanding the garden on both sides to provide additional habitat and enhance the aesthetics around this area. 

Our first Wednesday closure of the year included a small-tine aerification on the putting greens. Small, 1/4" coring tines were used to open up the soil profile in order to reduce compaction, promote oxygen exchange and encourage new root growth. The greens were topdressed prior to aerifying in order to fill the holes and incorporate sand into the soil profile.

Following aerification, the sand was brushed in and rolled for smoothness

During this one-day closure, we also had a contractor on property to conduct our annual root pruning of the golf course. Trees compete with turfgrass for both water and nutrients. The root pruning is a one-day process with a tractor-mounted pruning system that makes its way around the golf course pruning roots around large trees. The machine that is used is very efficient, with minimal surface disruption and virtually no cleanup necessary. It severs roots up to 6" in diameter and slices to a depth of 10" into the soil. This process prevents tree root encroachment into the turfgrass, ultimately eliminating the loss of water and nutrients. 

Tree root pruning is an annual process that promotes turfgrass health without causing harm to the trees

Our annual Curfew application is scheduled during our June 6th - 8th closure. Curfew is a soil fumigant and is extremely effective in eradicating plant-parasitic nematodes. Nematodes are microscopic roundworms that feed on living plant tissue. These extremely destructive pests can potentially kill very large areas of turf. During this application, Curfew is injected into the soil as a liquid. It then volatilizes and moves through the soil, eradicating the unwanted pests. Following the application, the injection lines or "slits" in the turf will be visible throughout the golf course for several weeks. A fertilizer application is scheduled soon after the application to expidite the recovery process and help heal the temporary scars. 

Lastly, we have formally achieved our recertification as a Certified Audubon Cooperative Sanctuary. Copperleaf initially earned this designation in 2006, with a recertification requirement every three years. Over the past 17 years, Copperleaf has continued to demonstrate a commitment to environmental sustainability through enhancing wildlife habitat and protecting natural resources.

April 2023 GCM Update

The CMGA Men's Invitational was a tremendous success this year, and capped off a wonderful season of golf at Copperleaf. As the temperatures continue to increase and the rains begin to fall, we shift our turfgrass focus from general maintenence to cultural practices. This includes verticutting, topdressing, aerification and all of the beneficial practices that provide us with fantastic year-round playing conditions. The rate of growth tremendously increases this time of the year, not only on the golf course turfgrass, but landscape material as well. This requires a shorter interval of time between mowings and trimmings, greatly increasing our work intensity.

Prior to April 12th, we had accumulated a grand total of 0.23 inches of rain for 2023 - well below average. The lakes were extremely low and the golf course was in desperate need of rainfall. Between April 12th and April 17th we were fortunate enough to receive a total of 2 inches of rainfall which saturated the soil profile and provided us with a nice flush. The turfgrass on the golf course now has a much more uniform appearance and the lakes have filled up with enough water to get us through the rainy season. 

We are currently in the process of identifying tee markers to use for our yellow, forward tees. You may notice some different options on holes #1, #2, and #3 as we gather feedback and ultimately decide on the best long-term solution to effectively identify this teeing ground. 

As mentioned in the March update, we are currently in the process of completing our recertification for our Aubudon Cooperative Sanctuary designation. This process includes case studies, backup documentation, application logs, scouting reports and other ways to demonstrate our high standard of environmental stewardship at Copperleaf. We have recently completed the installation of our butterfly garden, which is located between holes #3 and #4, to the right of the bridge before #4 tee. We filled this area with a variety of pollinating plants such as milkweed, lantana, sage, firespike, firebush, sweet almond, powderpuff, passion vine, blue daze, tibochina, hibiscus and jasmine. The butterfly population has already increased in this area, and we are hopeful that this area provides a suitable habitat for years to come.

Next week, we will be adding pinestraw to key areas around greens and tees. This application is scheduled every spring and will enhance aesthetics in addition to providing erosion and weed control. 

Lastly, I wanted to share an infographic developed by the USGA and GCSAA to serve as a reminder to always do your best to leave the golf course in better shape than you found it. The Golf Course Maintenance team works very hard to provide high quality playing conditions, and we greatly appreciate your help in practicing proper course etiquette.
