Many have asked me over the last week what the white lines are painted around the greens. Over years of mowing the proper collar width and area change and migrate. Since we will be aerifying next week, it is the perfect time to correct any issues like this. Attached are photos of the lines painted on 2 of our greens. To note, a few collars are being pushed back towards the rough which in turn is causing us to scalp the greens back. These scalped areas will quickly recover, I have no concern over them.
