Picking the right grass for a Kentucky golf course means winning a battle against the climate, and for modern courses, the champion of that fight is increasingly a specially bred Bermuda grass. These new varieties are nothing like the Bermuda of old, they are engineered for superior playability and survival in the challenging transition zone. This article will walk you through exactly why Bermuda grass is now a top choice for Kentucky, what factors to consider when choosing a variety, and which specific types deliver the best performance for greens, tees, and fairways.
Kentucky’s Climate: The Transition Zone Advantage
If you've played golf across the United States, you know that courses in the north look and feel different from those in the south. Northern courses typically use cool-season grasses like Bentgrass and Kentucky Bluegrass, which thrive in moderate summers but can struggle in high heat. Southern courses rely on warm-season grasses like Bermuda and Zoysia, which love the heat but go dormant and turn brown during cold winters.
Kentucky sits squarely in the middle of these two regions, in an area superintendents call the "transition zone." For decades, this presented a tough problem. The summers are hot and humid enough to badly stress or even kill cool-season grasses, while the winters are often cold enough to cause significant winterkill on traditional warm-season grasses. It forces a compromise that can lead to subpar conditions for a portion of the year, no matter what grass is chosen.
This is where modern Turfgrass breeding has changed the game. Scientists have successfully developed new hybrid Bermuda grass varieties with vastly improved cold tolerance. These grasses can handle Kentucky's hot summers with ease while also possessing the strength to survive freezing winter temperatures. The result is a turf that provides a dense, durable, and consistent playing surface through the heart of the golf season, finally offering a no-compromise solution for the transition zone.
Key Qualities to Look For in a Bermuda Grass Variety
Not all Bermuda grasses are created equal, especially when you're looking for one tough enough for Kentucky. When course managers are deciding on the best fit, they evaluate each variety against a specific set of performance criteria.
_Priority #1:_ Excellent Cold Tolerance
This is the most important factor for any Bermuda grass in Kentucky. Without it, you risk widespread turf loss - known as "winterkill" - after a particularly cold winter. Newer, improved varieties are selected specifically for their ability to withstand lower temperatures for longer periods. Top-tier varieties also offer better spring green-up, meaning they are quicker to come out of dormancy and regain their vibrant green color as temperatures rise, extending the playing season.
Density and Wear Tolerance
Golf courses are high-traffic areas. The turf is stressed constantly by golf carts, shearing from golf spikes, and, of course, countless divots. A good Bermuda variety needs to be dense and aggressive enough to handle this wear and tear. Density helps the ball sit up nicely on the fairway, creating an ideal lie. An aggressive growth habit - meaning the grass spreads quickly via runners (stolons and rhizomes) - allows it to rapidly recover from divots and damage, keeping the playing surface in top shape.
Drought and Heat Resistance
This is Bermuda grass's natural advantage. As a warm-season grass, it excels in the heat and requires significantly less water than cool-season grasses to stay healthy during a hot Kentucky summer. This translates directly into more resilient turf during heatwaves and substantial savings on irrigation costs.
Specific Playing Surface Needs
Putting Greens
Greens require a very specific type of Bermuda known as an "ultradwarf." These varieties have an extremely fine leaf texture and a vertical growth habit, allowing them to be mowed at very low heights (.125 inches or even lower) to create a smooth, true putting surface. They also feature incredible turf density a high shoot density to provide that pure roll every golfer looks for.
Fairways & Tees
For fairways and tees, the focus shifts slightly more towards durability. You want a variety that provides that classic 'ball-sitting-up' lie but can also recover from divots extremely fast. Fine texture is still desirable, but it's balanced with the need for aggressive, resilient growth.
Rough
The rough doesn't need to be as pristine as fairways or tees. Here, a slightly more aggressive and less manicured variety can be used. The goals for the rough are typically excellent durability, lower maintenance requirements, and great color.
Top-Performing Bermuda Grass Cultivars for Kentucky
When selecting turf for a high-end golf course, you're not heading to the local garden center for a bag of seed. The top-performing Bermuda grasses are sterile hybrids, meaning they do not produce viable seed and must be planted vegetatively using either sod (rolls of mature turf) or sprigs (chopped up stems and roots). Here are some of the elite varieties proven to perform in Kentucky's transition zone.
For Fairways, Tees, and Rough
- Latitude 36® Bermuda grass: Widely considered the gold standard for transition zone fairways. Latitude 36 is celebrated for its exceptional cold hardiness, which was proven during extensive testing at universities across the country, including in Oklahoma and Kentucky. It also has a very fine texture, outstanding wear tolerance, and beautiful dark green color. Courses that choose Latitude 36 get an elite playing surface that holds up to traffic and cold.
- NorthBridge® Bermuda grass: Another top contender, NorthBridge is known for having a similar fine texture and great cold tolerance to Latitude 36, but with a slightly more aggressive growth habit. This makes its recovery from injury or divots exceptionally fast, allowing it to heal quickly even under heavy play.
For Putting Greens
- Champion G-12 Bermuda grass: This newer ultradwarf has gained significant popularity on transition zone courses. Developed from the original Champion Dwarf, G-12 was bred to have a better combination of a strong root system, improved heat tolerance and good cold hardiness giving course maintenance crews an easier-to-manage green that still offers a top-tier putting experience.
- TifEagle Bermuda Grass: For a long time, TifEagle was the most popular ultradwarf Bermuda grass on greens around the world. It’s known for its incredibly fine texture and high shoot density, producing a very pure putting surface. While newer varieties might offer slightly better performance in terms of management in the Transition Zone, TifEagle remains a proven and reliable choice with a long track record of success.
A Quick Guide to Establishing Bermuda: The Grow-In
Establishing these grasses is a precise process and almost always done in the summer to take advantage of the heat Bermuda loves. Here is a simplified overview of how it works:
- Soil Prep: The ground is cultivated, graded for proper drainage, and amended based on soil tests to create an ideal seedbed. A starter fertilizer is typically incorporated into the soil.
- Timing: Planting must wait until late spring or early summer when soil temperatures are consistently 65-70°F or higher. Attempting to plant earlier when it’s too cool will result in failure.
- Sprigging: Millions of sprigs (the vegetative plant parts) are broadcast over the prepared soil. They are then lightly disked or rolled to ensure good soil contact.
- Water and Sun: This is the “grow-in” period. The newly planted sprigs require frequent, light watering to stay moist but not saturated. With plenty of summer sun and heat, the sprigs will begin to root and spread, eventually knitting together to form a solid mat of turf.
- Nurturing: Throughout the grow-in, a carefully managed program of fertilization and mowing is implemented to encourage aggressive growth and a dense, healthy stand of turf before fall and winter arrive.
Final Thoughts
Choosing the right Bermuda grass is a strategic decision that balances Kentucky's demanding climate with the high expectations of golfers. By selecting a modern, cold-tolerant variety known for its durability and playability, from respected cultivars like Latitude 36 for fairways to an ultradwarf like Champion G-12 for greens, a course can deliver pristine conditions throughout the heart of the golf season.
