Concord Country Club: Rooting and Renovation with Holganix

Holganix case study

Located in beautiful Brandywine Valley, Pennsylvania, Concord Country Club is a family and golf-oriented club that boasts a William Flynn-designed 18-hole golf course. Golf Superintendent, Greg D’Antonio, has been nurturing the course at Concord over the past 10 years. 

In 2016, Greg started using HGX PRO Bio 800+ Golf and HGX PRO Blue Sky 21-0-0 on his course after searching for a way to shorten his recovery time after renovation work. Over the past four years, Greg reports he’s seen swifter rooting when sodding or seeding, fertilizer reductions, more consistent foliage growth, and reduced environmental pressures from weather and disease.

Which Holganix products do you use?

“We use a combination of the Bio 800+ Golf and the Blue Sky 21-0-0,” explains Greg.

What results have you seen with Holganix products?

“The root development is what really sold me on Holganix,” explains Greg. Concord Country Club has done a lot of renovation work over the last five years, yet despite the challenge of managing a renovation, Greg’s team needs to get the course back to peak playability as quickly as possible. 

“Using the Holganix products during sodding and seeding really helps me get the turf rooted in quickly, and that turf is better able to handle the foot traffic from golfers,” reports Greg. When he compares a renovation at Concord Country Club with Holganix products to previous renovations without Holganix, Greg reports there is a stark difference. 

Greg also prefers to push the renovations into late fall when it becomes vital to get turf established before winter temperatures stress the turf. “People have been pleasantly surprised by the results we get,” explains Greg. “And, when I have third-party consultants come to the course to review the renovations they are always extremely complimentary of how quickly we get turf rooted in.” 

In addition to seeing results during renovations, Greg reports that he has been able to reduce his nitrogen rates by 50% on fairways and has eliminated the need for granule applications on the roughs. “From a business perspective, it’s important to be as efficient as possible with the budget,” states Greg. “So, the ability to reduce nitrogen without sacrificing playability, plant health, or appearance is critical.” 

Further, Greg reports he has more consistent growth, “without those peaks and valleys.” Plus, Greg explains he’s seen less pressure from environmental stressors like weather and disease. “Even in drought-like times, we’ve maintained good turf density. We’ve also seen fewer outbreaks of disease.”

What is your background as a superintendent?

Greg has been at Concord Country Club for 10 years but has been caring for golf courses for 23 years. He received his degree in Turf Grass Science from Penn State University and is currently attending West Chester University for his MBA. 

“I was naturally drawn to studying turfgrass science at Penn State. I loved that being a superintendent meant being outside, and I also have strong attention to detail. I love the challenge of trying to reach peak perfection at the course”
