For those who don't know what grain is when referring when talking about grass, grain is referring to the tendency of the leaves of the grass to grow in a specific direction. The grain is what gives golf courses striping, or different color patterns in the grass. There are old wive's tales about grass growing towards water or the setting sun, but that's all not true. The truth is, there's no known reason why a grass tends to grow / or lean a certain direction. What is known is that grain is a natural phenomenon and it has to be managed.
Here is a picture of some grain on our Celebration Bermuda grass fairways.
All of the grass in the above picture is Celebration, it has just developed some severe grain. The way we manage the grain during the active growing season is through heavy vertical mowings and frequent grooming. Now that the weather is warming up and will continue to warm up, I can begin to work on managing the grain. Excessive grain control through the cold winter months can lead to thinning turf and bare ground so I do not do a lot of grain control through the winter months.
So rest assured that the golf course isn't being plagued with the return of all the different types of Bermuda grass we had prior to the renovation. What you are seeing is just the Celebration grass growing strong and doing its thing. The Celebration's strong growth habit is the exact reason why it was chosen for the renovation.
