As we are all aware, it is very important to fix at least two ball marks on each green. This makes the playing experience much more enjoyable for the following groups. What some may not know is that especially on our new greens it is even more important to fix the ball marks. If a ball mark is not repaired properly, this spot is very susceptible to having Poa Annua invade into that spot. As part of our Poa Annua control, we please ask that ball marks be repaired.
