Among the grasses, the width of the leaves is very thin, the texture of the grass is delicate, and the density is very high.
It can be said to be the 'top variety' most suitable for use on greens.
It has a much faster growth rate and has faster regeneration ability than other grasses.
The cutting height can be reduced to the minimum, which is very good for the ball's fast rolling speed.
As a result, it is most suitable for high green putting quality spheres.

Green representative variety
Among the grasses, the width of the leaves is very thin, the texture of the grass is delicate, and the density is very high. When I see customers visiting the golf course with golf clubs in hand in the hot summer like these days, I think that these people are really serious about golf. In this heat, can coming to the golf course to exercise instead of going to the cool sea or mountains be a way to avoid the heat? The answer is “yes.”
When grass under the scorching sun receives sunlight, the grass leaves reflect about 10% of the light, lose about 40% as heat of vaporization through transpiration, and use about 5% for photosynthesis, so only about 45% is converted into heat energy and causes the heat radiation that we feel hot. In other words, when you come to a golf course, you only feel about 45% of the heat you feel in the city, but if a tee shot goes smoothly and a mountain breeze blows at that time, there is no better summer vacation than this.
Then, does the grass that cools golf course customers also feel the heat? Since grass is a living, breathing organism, it naturally reacts sensitively to temperature changes. In particular, the grass (bent grass) that forms the greens is a plant that was originally native to the Mediterranean region of Europe. It was later brought to the United States and bred as grass for golf course greens, but its growing environment is similar to its original home, the Mediterranean climate (average daytime temperature of 10-15℃, high humidity, and relatively cool at night). Therefore, it would be very difficult for this bent grass that immigrated to Korea to adapt to our weather, which fluctuates around 30℃. Furthermore, the stress of having to cut the leaves by about 4mm every day is enormous.
It can be said to be the 'top variety' most suitable for use on greens.
It has a much faster growth rate and has faster regeneration ability than other grasses.
The cutting height can be reduced to the minimum, which is very good for the ball's fast rolling speed.
As a result, it is most suitable for high green putting quality spheres.
Difficult management
Korean grass, bentgrass
Korean grass is mostly used in large areas such as golf courses, soccer fields, and baseball fields, and it remains green when the temperature rises above 5 degrees.
Because it grows quickly, the grass needs to be mowed frequently, and it is susceptible to pests and diseases, so it is a hassle to maintain it frequently.
In particular, creeping bentgrass is considered one of the most difficult to maintain of all grass species.
Because it is the lowest-cut and densest grass, it is used only in limited areas such as golf course greens and tennis greens, which are special sports facilities.
It grows very quickly and has high resilience, but in hot and humid climates, growth is poor and there is a high risk of disease.
In particular, our country has distinct changes in the four seasons, and it is very difficult to manage during the summer drought with high humidity and long periods of direct sunlight, such as the summer rainy season.
Even in winter, when the temperature continues to drop below 5 degrees Celsius, and when growth has stopped and there is constant pressure from visitors, management cannot be lax.
Green and fringe
The edge or border of the green, or more precisely the boundary between the green and the fairway, is called the plunge.

There are many expressions that are used comparatively.
Like the green, the plunge is also an important management area of the green.
It usually forms the green border with a size of about 30 to 50 cm. It is planted with Kentucky bluegrass, a grass about 10 mm longer than the green.
If you forecast the green at 2.7mm to 4.0mm per day, you should also forecast the plunge about once a week.
