The United States is home to thousands of golf courses. Regardless of the time of year, many of these golf courses have lush, green grass. (This is especially impressive considering how difficult it is to keep even a small yard green all year round.)
Golf courses use a variety of techniques to maintain the health of their grass. Read my blog at https://darrellkindley.wordpress.com/2019/03/18/how-a-golf-course-maintains-their-green-grass/ for tips and tricks used by maintenance pros on golf course grass.
It can be great information to have for small talk on the green, or you can use it to help your lawn at home!
