For Paul B. Latshaw, Director of Grounds Operations at Muirfield Village Golf Club, it all started in the fall of 2013. “That’s when I first heard about Holganix,” says Paul. “The fact that Holganix began as a compost tea intrigued me.”
Paul started testing Holganix on areas where Muirfield had tree and stump removal and during post aeration treatments, then expanded to greens. By 2014, Paul started using Holganix in just about every aspect of Muirfield’s turf program including: greens, tees, fairways, renovation projects, flowers, trees and shrubs.
Results on greens and tees
“I think one of the biggest benefits of Holganix is root depth and density, especially on greens. It’s way better than anything we’ve seen prior to using Holganix,” says Paul. A lack of surge growth was another asset. “I never saw the huge release of nitrogen from all the bacteria in the soil profile. That’s good because I was able to control my clipping yield.”
Paul started using Holganix on his greens in 2013 with an initial application rate of 14 ounces per 1,000 square feet. Since then he’s applied Holganix monthly during the growing season at a rate of 7 ounces per 1,000 square feet. His greens primarily contain forms of bentgrass with 20% to 30% Poa invasion depending on the green. Looking forward, “we might try to do Holganix on greens on a bi-weekly cycle or a little bit sooner.”
For his bentgrass tees, Paul started with an initial application of 7 ounces per 1,000 square feet and has continued using it at that rate on a monthly schedule. “The Holganix program really helps us out with our plant health on greens and tees,” states Paul.
Results on fairways
“We’ve tried just about every product on fairways when it comes to removing thatch. Holganix is the first product I’ve used that actually has merit and it’s something we continue to monitor,” says Paul. It’s also the “first year we didn’t have an anthracnose break out on fairways,” says Paul. While it’s difficult to say that Holganix is the number one reason for the decrease in anthracnose, Paul affirms that it’s definitely played a role. Overall, when comparing Holganix to check plots, areas treated with Holganix “had more vigor than those not applied with Holganix.”
Paul started using Holganix on a couple of select fairways in the spring of 2013. By July of 2013, Paul was using Holganix on all fairways, “because you could see the difference.” Paul applies Holganix to his predominantly bentgrass fairways at a rate of 7 ounces per 1,000 square feet with his monthly wetting agent program.
Results on renovation projects
“We really started seeing a big rooting benefit with Holganix in 2013.” Between the Memorial and President’s Cup, the club decided to increase a green by 40 yards in length, in addition to adding a tee and two acres of undisturbed turf area. “It ended up being more complex than anticipated… and I was concerned about playability for the President’s Cup.” On August 13, 2013, 45 days before the President’s Cup, sod was installed. “The first thing we did was apply 14 ounces of Holganix Golf.”
By September 13, the renovation looked fantastic. “As far as rooting and establishment, I’ve never been able to get sod established this quickly, especially at such a difficult time of year.” While Paul did have staff hand watering and monitoring the turf at all times, “Holganix really helped. We had no issues going into the President’s Cup.”
Results on greenhouse production: trees, shrubs and flowers
Muirfield Village Golf Club has two, 3,000 square foot greenhouses containing 2,200 hanging baskets and 9,000 plants. Muirfield’s Horticulturist, Tim Hollowell, CGCS started using Holganix in the greenhouses in 2012. During production, Tim makes monthly applications of Holganix to his flowers using Holganix Bloom. He’s seen an increase in drought tolerance, less disease, and an extended bloom time. For example, “We have 1,000 rhododendrons. I lose at least a couple dozen rhododendrons due to phytopthora each year,” claims Tim. “Since using Holganix, I’ve seen huge reductions in the number of lost rhododendrons. They’re much healthier.” Click here to learn more about Tim’s results.
You might think Paul has implemented Holganix in every applicable area of his course, but he is actually considering adding Holganix to roughs and natural grass areas too. Building the soil food web adjacent to the playable course areas only helps maintain the balance within the greens tees and fairways. It’s all an ecosystem, and Holganix keeps it in harmony.
