One of the biggest questions that I get year round is, "What are we going to do about all of the ballmarks on the greens?". The simple answer is that each golfer is responsible for fixing their own ballmark. Now, realistically that's not going to happen, but I do encourage everyone at the club to fix theirs plus one more. I started having the greens mowers take ballmark repair tools with them each morning so they could walk the entire green fixing marks before they mowed. I have been very happy with the results of this process. The problem is that we only have the staff to do this in the peak months of the season. So, please remember to fix your ballmarks. The video below is an example of how to properly repair a ballmark.
Notice the guy in the video was using a golf tee. You don't have to have a divot repair tool to fix the ballmarks (I use my pocket knife). Also, he just pulls the surface turf back to the center of the mark, he does not lift the center, this is textbook repair practice.
If your out there playing and you see someone in your group not fixing their ballmarks, ask them kindly if they have a tool, know how to, or just to please fix them. Thanks for your help.
