Verticuting Greens

Vertical mowing, or "Verticuting" is a cultural practice used on golf courses for a number of reasons. The first is to sever lateral growth and promote an upright growth habit in the grass. Bentgrass that lies parallel to the putting surface creates "grain." Johnny Miller used to rail against this grain during television broadcasts of PGA tour events. As an aside, the courses the professionals play on do not have grain on the greens. Most of the time his comments Grass that stands upright will promote a faster, truer green. It also improves the quality of cut for the mowers. Depending on how deep the mowers are set, it can also remove a large amount of thatch and organic matter. It is a practice that I would like to implement three or four times a year.

Here is Jim verticutting #3 green at Leslie Park.



Here is the putting surface after vertical mowing. Not the organic matter and thatch.


After the mowing, we blow off the organic matter and thatch that is brought to the surface. We then spread a very light layer of sand over the green and brush it in. This brushing also has the benefit of standing up some of the blades of grass that the machine cut but did not lift. Then we mow the green. After a few days, you will not see the lines any more, but you will hopefully notice a smoother ball roll.

Thanks once again for an interesting look into how you maintain our greens and the course.

What I hope you will do sometime this summer is take some photos after a heavy rain downpour. It would be interesting to see how the new drainage on the back nine works.
